Tornadoes are violent rotating columns of air that extend from thunderstorms to the ground. The strongest tornadoes can have wind speeds over 300 mph, destroying buildings, uprooting trees, and hurling vehicles long distances. On average, 1000 tornadoes are reported in the United States each year. Tornadoes come in different types including waterspout tornadoes over water, dust devil tornadoes that don't connect to clouds, and supercell tornadoes which are the largest and most dangerous, sometimes being over a mile wide and lasting for hours. While the exact formation of tornadoes is not fully understood, they typically form from rotating thunderstorm clouds called supercells.

Sumatras
Sumatra squalls are lines of thunderstorms that develop over Sumatra and the Malacca Straits between March and November each year during the southwest monsoon season. They typically move east towards Singapore and peninsular Malaysia in the early morning hours, bringing sudden strong gusty winds and heavy rain lasting 1-2 hours. Maximum wind gusts of 93 km/h have been recorded with these squalls. They form at night due to conditions like the diurnal wind variation, katabatic winds from nearby highlands, adiabatic cooling, high humidity and convection over the Straits of Malacca.
Tornadoes
Tornadoes are violent rotating columns of air that extend from thunderstorms to the ground, with some capable of wind speeds over 300 mph. They typically form when warm, moist air meets cool, dry air, creating instability and a change in wind direction and speed that causes horizontal spinning to become vertical. Most strong tornadoes develop within the rotating air extending through the storm. On average, around 1000 tornadoes occur each year in the USA, lasting only a few minutes most often between 3-9pm, with three out of four occurring in the USA. A water spout is essentially a tornado that forms over water.
Tornadoes
Tornadoes form from severe thunderstorms called supercells. As wind swirls into the storm, a funnel forms that spins faster and faster, sucking more air and objects into its extremely low pressure area. Tornadoes can destroy houses, throw objects high into the sky, and rip apart everything in their paths as they touch down across parts of the central US, especially in an area called Tornado Alley. Different types of tornadoes include supercell tornadoes, dust devils, firewhirls, gustnadoes, landspouts, and waterspouts.
Tornadoes
A tornado is a funnel-shaped cloud that sometimes touches the ground, destroying everything in its path. Tornadoes form from powerful thunderstorms called supercell clouds and can have wind speeds over 400 mph. They most commonly occur during the spring and summer months in parts of the United States.
Tornadoes
Tornadoes are rotating columns of air attached to thunderstorms that can reach the ground. They occur most frequently in the central US between March and August. Tornado wind speeds can exceed 300 mph and they can be over a mile wide. The damage and strength of tornadoes is measured using the Fujita scale, ranging from F0 to F5. Over the past 70 years in the US, tornadoes have caused over $25 billion in damage and injured or killed over 80,000 people.

This document summarizes information about tornadoes, including:
1. Tornadoes are violently rotating columns of air that extend from thunderstorms to the ground.
2. There are four main types of tornadoes: waterspouts, gustnados, multi-vortex tornadoes, and landspouts.
3. Tornadoes most frequently occur in the United States and can cause extensive damage, such as the 1999 Salt Lake City tornado that caused over $170 million in damage.
Tornados
A tornado is a violently rotating funnel-shaped cloud extending from a thunderstorm to the ground, with wind speeds exceeding 200 mph. The deadliest tornado on record was the 1925 Tri-State Tornado, which killed 695 people and traveled over 300 miles. The largest tornado was the 2013 El Reno, Oklahoma EF-5 tornado, which was analyzed using Doppler radar. Tornadoes form when cold air drops and warm air rises in a thunderstorm, causing the warm air to twist into a funnel cloud.

What is a tornado?
A tornado is a rotating column of air that extends from a thunderstorm to the ground. Most tornadoes have wind speeds between 40-110 mph but the strongest can exceed 300 mph. Tornadoes form from thunderstorms called supercells that contain rotating updrafts. As rain drags down rotating air, a funnel cloud may form and touch down as a tornado. Tornadoes grow strongest as they receive warm air but then weaken as surrounding winds cut off the supply, causing the tornado to dissipate.
Tornadoes!
Tornadoes form after clouds darken and a funnel forms within minutes. Strong tornadoes can reach over 300 mph and suck up anything in their path, dropping debris after the tornado passes. While smaller tornadoes, known as sisters of tornadoes, are less powerful than main tornadoes they can still be dangerous and carry objects like cars. Tornadoes are rated on the Fujita scale from F1 to F5 based on damage caused, with F5 being the most severe and destructive.

Tornado formation and occurrence are explained detailing how mesocyclones form and funnel clouds develop. Hurricanes are introduced covering their profile, formation from tropical disturbances, and decay when they move over land or cooler waters.
Severe Weather
Tornadoes form from strong storm clouds called supercells. There are different types of tornadoes such as waterspouts, land spouts, and multiple vortex tornadoes. A tornado is formed when warm and cold air meet, moving in different directions at different speeds, creating a wall cloud that can spawn a tornado spinning at 35 mph or more. Tornadoes most commonly occur in Tornado Alley in the Great Plains of the US, where over 500 tornadoes are reported each year. The deadliest tornado in US history was the 1925 Tri-State Tornado, which killed 695 people as it traveled through Missouri, Illinois, and Indiana.
Tornado
Tornados are violently destructive columns of air that form over land in the shape of a funnel. They typically have wind speeds between 64-177 km/h and stretch over 75m across. Different types of tornados include supercell tornados, landspouts, firewhirls, gustnados, and waterspouts. Tornadoes form when warm moist air collides with cold dry air, creating a whirling wind that draws air into its center to form a funnel. Weather services issue tornado watches when conditions are right for tornadoes and tornado warnings when a tornado has been sighted on radar or visually. Tornados can cause significant damage and loss of life.

Thunderstorms
This is about thunderstorms and how to be safe in such situation and also about thunderstorms detection.
Natural Disasters
A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. They form where warm moist air meets cold dry air and can reach wind speeds over 300 mph. Most tornadoes last less than 10 minutes and cause extreme damage due to their high winds.
TORNADOS
Tornadoes are violently rotating columns of air that form during severe thunderstorms. They develop when warm, low-pressure air rises rapidly and condenses into a funnel cloud. Tornadoes are classified based on where they form - over land or water. The most powerful tornadoes can have winds over 300 mph and paths of destruction miles long, while smaller "gustnadoes" form from downdrafts. Tornadoes develop within thunderstorms and follow the path of the storm, appearing to "hop" as the vortex is disturbed and reforms along the way. They are rated based on the original Fujita Scale which classified tornado damage and estimated wind speeds.
Tornadoes
Tornadoes are relatively small, localized low-pressure areas associated with powerful thunderstorms under cumulonimbus clouds. They typically have a diameter of 820 feet and whirling winds of 150 mph. Most tornadoes rotate counterclockwise in the northern hemisphere. Tornadoes form when a vortex touches the ground and cloud base. They most commonly occur with fast-moving cold fronts in the central US, drawing warm, moist air from the Gulf of Mexico north and west. While damage from tornadoes can be severe, meteorologists are improving forecasting and detection methods like Doppler radar to better predict and track tornadoes.
Tornado disaster management
A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. There are several types of tornadoes, including waterspouts that form over water, gustnadoes that are short-lived and do not connect to the cloud base, and multi-vortex tornadoes that have multiple rotating vortices around the main vortex. Landspouts are similar to waterspouts but form over land. Tornadoes occur most frequently in the central United States, known as Tornado Alley. The Enhanced Fujita Scale is used to rate tornado strength based on wind speeds and damage caused.
Thunderstorms
Thunderstorms are storms that produce lightning and thunder. They form from single or clusters of cumulonimbus clouds and can affect small or large areas. There are different types of thunderstorms including air-mass and severe thunderstorms. Thunderstorms go through various stages of development from cumulus to mature to dissipating. Microbursts are strong localized downdrafts under thunderstorms that can cause damage. Lightning forms due to separation of charges within thunderclouds and can be dangerous, so safety precautions should be taken during storms.
Thunderstorms
Thunderstorms form from moisture, unstable air that rises rapidly, and lift from factors like fronts or mountains. Thunder is caused by lightning opening a small channel in the air, which then collapses back, creating the sound we hear. While thunderstorms produce noise and light, it is the heavy rain and wind that can damage homes and property, potentially leaving people without shelter or food.
Thunderstorms
This document discusses thunderstorms and tornadoes. It begins by defining a thunderstorm and outlining the typical stages of thunderstorm development: the cumulus stage dominated by updrafts, the mature stage with both updrafts and downdrafts, and the dissipating stage dominated by downdrafts. It then contrasts air mass thunderstorms and severe thunderstorms, noting that severe storms are longer-lived due to wind shear tilting the updraft. Finally, it describes supercell thunderstorms which can spawn tornadoes due to their rotating mesocyclone updraft structure.
AP Style - Weather
A warning means a storm has been detected, like a severe thunderstorm warning. A watch means conditions are right for a storm, such as a tornado watch when conditions exist but a tornado hasn't touched down. A tsunami is a giant wave caused by underwater disturbances, unlike a tidal wave which is incorrectly used as a synonym and not caused by underwater events. Tropical storms have winds from 39-73 mph, hurricanes have winds over 74 mph and are the same as typhoons, and high winds refer to winds over 39 mph expected to last over an hour.

The document discusses tornadoes and provides information about their formation, location, and characteristics. Tornadoes form from warm moist air interacting with cold air masses. They most commonly occur in the central US, known as Tornado Alley. Tornadoes are still not fully understood as their behavior can be unpredictable, sometimes dissipating suddenly or combining with other tornadoes. The document also provides historical facts about significant tornadoes and discusses what can be done to improve warnings and shelter from these dangerous storms.
Thunderstorms -Basics
Thunderstorms are most likely to occur in the spring and summer months and during the afternoon and evening hours, but they can occur year-round and at all hours. Thunderstorms frequently occur in the late afternoon and at night in the Plains states. This module highlights the basics of thunderstorms.

Weather Phenomena by Ali Hussain
This document discusses three weather phenomena: tornadoes, lightning, and hurricanes. It provides information on how each forms and its potential impacts. Tornadoes form from rotating thunderstorms and can have winds over 250 mph, destroying buildings and flinging cars. Lightning forms in charged storm clouds and can damage electronics even from a distance. Hurricanes originate over warm ocean waters and have potential to be the most dangerous, causing widespread property damage, storm surges, and loss of life from high winds and flooding.

A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. Tornadoes form from thunderstorms when warm, moist air collides with cool, dry air, causing instability. The typical tornado is 15 miles wide and lasts 30 minutes. Tornado Alley in the central US has the highest risk of tornadoes. Tornadoes are most common between March and June and between 3-9pm. They can be classified by wind speed and damage on the Fujita scale from F0 to F5. Waterspouts are weak tornadoes that form over water.
Tornadoes & hurricanes
Tornadoes and hurricanes are powerful storms that form from specific weather conditions. Tornadoes are rotating columns of air that extend from thunderstorms to the ground, with wind speeds up to 300 mph. They form when warm and cold air masses meet and create instability. Hurricanes are large storms up to 600 miles wide with strong inward spiraling winds between 75-200 mph that gather heat from warm ocean waters and can cause damage when making landfall. Both storms can be predicted to some degree with watches and warnings issued ahead of their arrival to provide time to take shelter.

A tornado is a violently rotating column of air extending from a thunderstorm to the ground. Tornadoes most commonly form in the central and southern US, known as Tornado Alley, where warm, moist air from the Gulf of Mexico collides with cool, dry air from Canada. The typical tornado is 15 miles wide, lasts 30 minutes, and rotates at wind speeds between 40-318 mph, causing damage ranging from broken tree branches to complete destruction depending on its strength on the Fujita scale.

Hurricanes are large, spiraling tropical storms that can have wind speeds over 160 mph. They form over warm ocean waters and are known as cyclones or typhoons in other parts of the world. Tornadoes form from thunderstorms when wind direction changes and wind speed increases with height, tilting rotating air vertically. About 1,000 tornadoes occur in the US each year resulting in around 80 deaths and 1,500 injuries.

Marlon ramtahal's presentation on tornadoes
Tornadoes are violently rotating columns of air that extend from thunderstorms to the ground. They can range from weak to incredibly destructive depending on the Fujita scale rating. To stay safe during a tornado, seek shelter in an interior room on the lowest floor of a building and avoid windows until the tornado passes. Tornadoes are most common in the central US region known as Tornado Alley but can occur anywhere under the right conditions.
Thunderstorms
Thunderstorms are formed by cumulonimbus clouds and are characterized by lightning and thunder. They develop when certain atmospheric conditions are met, such as unstable lapse rates and sufficient water vapor. Thunderstorms can be triggered by different mechanisms like surface heating, frontal lifting, orographic lifting, and convergence. There are different types of thunderstorms including single cell, multicell, and supercells. Thunderstorms pose various hazards to aviation like turbulence, icing, hail, wind shear, lightning, tornadoes, and microbursts. Pilots can detect and avoid thunderstorms using weather radar and visual sighting, and recommended distances of avoidance depend on aircraft altitude.

Ashley ray blizzards
A blizzard is a winter storm with winds over 56 km/h, heavy snowfall, and low visibility lasting more than 3 hours. Blizzards occur when cold air interacts with regions of low and high atmospheric pressure, bringing heavy snow and strong winds that can cause whiteout conditions, sickness, damage from falling trees and power lines, and dangers from hypothermia or frostbite. The Blizzard of 1888 was one of the worst blizzards in U.S. history, dumping over 40 inches of snow with winds over 45 mph across many Northeastern states and claiming over 400 lives.
TORNADOES
Tornados are funnel-shaped clouds that touch the ground, can reach speeds up to 300 mph, and come in strength categories from F1 to F7. They form when winds at different heights blow in different directions and speeds, resulting in a funnel cloud that can demolish homes and throw people and animals miles away, causing injury or death.

Tornadoes form when warm, humid air meets cooler air, causing the warm air to rise rapidly and begin to spin. The document discusses two famous tornadoes - the 1899 tornado in New Richmond, Wisconsin that was 3,000 feet long and 1,000 feet wide and killed 26 people from different families, and tornadoes can vary in size and duration, with some being more destructive than others by lifting cars, damaging property over 50 miles, and causing rain.
Hurricanes
Hurricanes are intense, rotating oceanic storms that form over warm tropical waters and can have very strong winds up to 60 mph. They require warm ocean waters, atmospheric moisture from evaporation, and wind patterns near the surface to form. Famous Hurricane Hugo in 1989 was a category 5 hurricane with 140 mph winds that caused extensive damage as it traveled from the Virgin Islands to South Carolina over two weeks, destroying homes, cars, crops, and killing many people and animals. Hurricanes can cause major damage through strong winds, heavy rain, and flooding that can take weeks or months to clean up.
Hurricanes
Hurricanes are low pressure tropical storms that form over warm ocean waters with winds of 74 mph or higher. They can be categorized from weak to strong and cause significant damage by destroying crops, buildings, and killing people and animals through high winds, flash floods, and contaminated water. Hurricane Hugo formed in September 1989 and caused $10 billion in damages as a powerful Category 5 hurricane when it hit South Carolina.
Blizzard
A blizzard forms when warm, moist air clashes with cold air, causing a thunderstorm that produces snow and high winds. Blizzards can be dangerous due to low visibility, freezing temperatures, and strong winds that cause damage and endanger lives. The worst blizzard on record was the Great Blizzard of 1888, which killed over 400 people and spanned March 11-14. A severe blizzard has temperatures below 10 degrees Fahrenheit, winds over 45 mph, visibility below 1/4 mile, and lasts at least 3 hours, with potential snowfall of 12.5 inches in 24 hours.
Blizzards
A blizzard is a snowstorm with winds over 56 km/h and temperatures below -10°C that lasts for at least 3 hours. Blizzards form when snowstorms collide with warm air and begin twisting, and they can accumulate over 3 feet of snow and cause damage like cracking roads and burying cars, which sometimes results in loss of life. Key factors for blizzards include wind speeds up to 35 mph and heavy snowfall that reduces visibility.
Tornadoes
Tornadoes form from storm clouds when hot and cold air mixes, creating a rapidly whirling funnel cloud that can touch down and cause extensive damage by ripping apart buildings, trees, cars, and homes with strong winds that vary in speed and direction with altitude. Tornadoes are rated on the Fujita scale from F1 to F5 based on the severity of damage caused, with an F5 being the most destructive.
tornados
Tornadoes are rapidly spinning funnel clouds that reach from thunderstorm clouds to the ground, causing mass destruction with winds that can send cars flying and destroy homes and buildings. They form when hot and cold air masses collide and start circulating intensely, with the force eventually producing a funnel. Some of the most destructive tornadoes include the 1953 Flint Beecher tornado in Michigan, which killed over 100 people and injured 900 with 100 mph winds that destroyed 20 homes.
Tornadoes presentation
The document summarizes tornadoes, describing their funnel shape and varying colors depending on debris. Tornadoes form from rotating thunderstorms when cold and warm air masses collide. They can rip apart buildings, uproot trees, lift animals, and destroy entire cities within minutes. Wind speeds often exceed 300 miles per hour and tornadoes cause rain, hail, and sleet. Some notable tornadoes include the 1953 Waco, Texas tornado that was a third of a mile wide and destroyed 23 miles of land.

Hurricane
A hurricane floods towns and cities, demolishes buildings, destroys crops, kills people and animals, and causes thousands of dollars in damage as it moves counterclockwise. It forms over warm ocean waters as thunderstorms wrap around the center, gaining heat and wind speeds up to 130 miles per hour with intense rain and humidity. Hurricane Katrina was one of the deadliest and costliest hurricanes, hitting New Orleans in 2005 and flooding the entire city.
Weather
Rain forms when water evaporates into clouds, condenses into droplets, and precipitates down as rain. Hurricanes are strong winds formed by heat at the equator that can erode rocks and dirt to form hills and mountains. Both rain and hurricanes weather rocks through erosion, moving sediment and contributing to landscape changes over time.
Severe Weather
Hurricanes are large tropical storms with heavy winds that form over warm ocean waters. They require warm ocean temperatures of at least 79 degrees Fahrenheit, moisture from the sea evaporating into the warm air, and wind patterns near the ocean's surface that pull winds inward. Hurricanes can last up to 8 days and become very destructive at higher categories, with Category 5 being the strongest designation for a hurricane with sustained winds over 155 mph. Hurricane Katrina, a Category 5 storm, caused massive damage of over $100 million and loss of over 1,800 lives when it struck New Orleans in August 2005.
Hurricanes
A hurricane is a large, swirling storm that forms over warm ocean waters near the equator. It features high winds and heavy rain that can cause catastrophic damage. When viewed from above, a hurricane looks like a large white vortex with a clear eye at the center. Hurricanes develop from rising warm, moist air that causes surrounding air to swirl inward and feed the growing storm. As they make landfall, hurricanes can rip off roofs, destroy homes and property, and lead to flooding and loss of life.
Hurricanes
A document discusses how hurricanes form over warm ocean waters and need storm energy, how hurricanes are steered by wind currents, and details of Hurricane Katrina which hit New Orleans in 2005, caused 1836 deaths, and caused widespread flooding and infrastructure damage through broken bridges and destroyed homes.
Severe Storms
Hurricane Hugo hit Puerto Rico in the morning of September 17th, 1989 and then made landfall in South Carolina around midnight, causing significant damage as it moved through the state. Hurricanes form over warm ocean waters and contain heavy rain, strong winds that can reach 74-200 mph, and an eye of calm weather at the center. They start as tropical storms that grow stronger as heat and moisture rise within the storm system.
Hurricane Hugo
Hurricane Hugo was a powerful hurricane that hit South Carolina and other areas in 1889, destroying homes and buildings with its strong winds and heavy rain. The document describes how hurricanes form from tropical storms and develop a distinctive spiral shape with an inner eye of calm. Hurricane Hugo had maximum sustained winds of 160 miles per hour, making it a very fast and destructive storm, as recalled by the author's mother who experienced its impact in South Carolina.
Hurricanes
Hurricanes are one of nature's most destructive forces. They can cause enormous damage through wind, flooding from storm surges and heavy rain, and other hazards like mudslides. Hurricane winds can reach speeds of up to 200 miles per hour. Hurricanes form over warm ocean waters through a process where moist air rises, condenses into clouds and releases latent heat. Hurricane Katrina made landfall in Mississippi and Louisiana in August 2005, causing extensive damage and loss of life from high winds and catastrophic flooding.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Tornado
- 1. Tornadoes… All about tornadoes and how they are formed. By: Amber Skinner
- 2. A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees. Damage paths can be in excess of one mile wide to 50 miles long. In an average year, 1000 tornadoes are reported nationwide. http://www.weatherwizkids.com/weather-tornado.htm This is a quote from weatherwizkids.com What Is Tornado
- 3. There are many types of tornadoes some of them are…. A Waterspout tornado A Dust Devil tornado Gustnadoes A supercell tornado And a landspout tornado Types of Tornadoes
- 4. A waterspout tornado is a column of spinning wind that forms downward from a cumulus cloud down to any body of water. The winds in a waterspout can reach a spinning point of 200 mph. Waterspout Tornadoes
- 5. They are swirls that go up and fizzle out in the clean air and they are not connected to the clouds while spinning. Dust Devil Tornadoes
- 6. Gustnadoes are very weak vortices that aren’t connected to the cloud base. And according to science are not actually tornadoes. They are commonly confused with a tornado and it takes a very good spotter to see the difference. Gustnadoes
- 7. A supercell tornado is the biggest and by far the strongest and most dangerous. They spin under a thunderstorm and their winds can get up to 300 mph. They can be at the very least one mile wide and last for hours and hours. Supercell Tornadoes
- 8. A landspout tornado is a narrow vortex that forms over land under several columns of cumulus clouds. Winds can reach up to 140 mph and only last for several minutes. But it is powerful. Landspout Tornadoes
- 10. At this point in time, formation of tornadoes are not fully understood by scientists. They usually form by a thunderstorm cloud called supercell. Although it isn’t true many people believe that tornadoes are not actually tornadoes unless there is a visible funnel cloud. How Tornadoes are Formed
- 11. They are the most violent storm. In an average year around 800 tornadoes are reported world wide….. An average tornado reaches up to 250 mph or more and can travel around 30 miles before stopping… One time there was a tornado that picked up a motel sign and carried it from Oklahoma to Arkansas. Facts About Tornadoes
- 12. What Tornadoes Look Like?
- 13. Destroy Buildings Can rip a house apart Can turn cows into a bomb [spins so fast that the cow pops…] Can throw a person above the clouds Rip apart anything in it’s path. What Does a Tornado do??????
- 14. The average wind speed is 112 mph. All kinds of precipitation Weather Factors
- 15. Name/nickname: Black Friday Tornado Date: July 31st 1987 Time: 2:59 pm Year: 1987 Location: Edmonton, Aberta, Canada Damage: 300 homes and $330 million in property damage. Deaths/Injuries: killed 27 and injured more than 300 people Storm Story http://en.wikipedia.org/wiki/Edmonton_Tornado
