This is a powerpoint that I had made for my computers in education class. My major is integrated science, so I thought a unit overview slideshow would fit.

    • Thunderstorms
    • What Makes a Thunderstorm?
      • Moisture : cloud formation & rain
      • Unstable air : relatively warm air rises rapidly
      • Lifting : from sea breezes and mountain interaction
    • Three Types of Thunderstorms
      • Air Mass
        • Result of localized convection in an unstable air mass
      • Frontal
        • Form right along or just ahead of a cold front
      • Orographic
        • This type of storm is the result of air that is forced upward by a mountain
    • Thunderstorm Facts
      • Every thunderstorm produces lightning
      • Heavy rain can lead to flash flooding
      • Strong winds, hail, and tornadoes may be associated with thunderstorms
    • Important Terms for Thunderstorms
      • A Severe Thunderstorm Watch can be issued by the National Weather Service station
        • This type of storm has winds of at least 58 mph or hail at least ¾ inch in diameter
      • A Severe Thunderstorm Warning is issued when a severe thunderstorm has actually been observed
    • Thunderstorm Safety Tips
      • Go inside and stay away from windows, doors, and porches
      • Stay away from trees and out of boats
      • Avoid plumbing fixtures and contact with electrical fixtures
      • Stay off the phone!
    • Tornadoes
    • What is a Tornado?
      • A tornado is a violently rotating column of air extending between, and in contact with, a cloud and the surface of the earth
      • Tornadoes can come one at a time or in clusters
      • They can also vary in size, length, width, direction of travel, and speed
    • How Do You Measure a Tornado?
      • Since February 1, 2008 tornadoes have been measured based on the Enhanced Fujita Scale (EF)
      • This scale helps determine the speed of a tornado from weakest to strongest
    • The Enhanced Fujita Scale
      • EF 0 65 to 85 MPH
      • EF 1 86 to 110 MPH
      • EF 2 111 to 135 MPH
      • EF 3 136 to 165 MPH
      • EF 4 166 to 200 MPH
      • EF 5 Over 200 MPH
    • When and Where Do Tornadoes Occur?
      • Tornadoes can occur in any state and any time of year
      • They typically occur from March to August
      • The most common tornadoes are in “Tornado Alley”
      • “ Tornado Alley” - Arkansas, Iowa, Kansas, Louisiana, Minnesota, North Dakota, Ohio, Oklahoma, South Dakota, and Texas
    • Important Terms for Tornadoes
      • Tornado Watch: weather conditions are likely for tornadoes to form in our area
      • Tornado Warning: A tornado has been sighted in our area
    • Tornado Safety Tips
      • Seek shelter immediately when a tornado warning is issued
        • Underground shelter is best
        • If not available, find an inside room, hallway, or closet on the lowest floor and away from windows
      • Listen to the radio or watch TV for updates on the storm
    • Hurricanes
    • What is a Hurricane?
      • A hurricane is an intense tropical weather system that has a well-defined circulation and sustained winds of 74 MPH or higher
    • How Do Hurricanes Form?
      • They form when they gather heat and energy through contact with warm ocean waters
      • Water evaporates from the water and the moisture produces a storm
      • They can also form when a wind pattern occurs near the surface of the ocean and spirals inward
    • Storms Associated with Hurricanes
      • Tropical Depression
        • An organized of clouds and thunderstorms at low level circulation with winds at a maximum of 39 mph
      • Tropical Storm
        • An organized system of strong thunderstorms with winds between 39 to 73 mph
    • When and Where Do Hurricanes Occur?
      • Hurricanes can occur during any time of the year
      • Hurricane season is from June 1 st to November 30 th
      • They can form in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the eastern Pacific Ocean
    • How Do You Measure a Hurricane?
      • Hurricanes are measured by their speed and it is split into categories
      • The categories range from one to five, with one being the weakest and five being the strongest
      • The classification of hurricane systems is called the Safir-Simpson Hurricane Scale
    • Safir-Simpson Hurricane Scale
      • Category One 74 to 95 MPH
      • Category Two 96 to 110 MPH
      • Category Three 111 to 130 MPH
      • Category Four 131 to 155 MPH
      • Category Five Winds greater then 155 MPH
      • Note: Hurricanes of Category Three or above are considered major hurricanes.
    • Why Do Hurricanes Have Names?
      • Hurricanes are named to help identify and keep track of storms as they move across the ocean
      • Atlantic hurricanes might have Spanish, French, or English names since they come in contact with the borders
      • Hurricanes are named alphabetically by the National Weather Service
    • Why Do Hurricanes Have Names? (2/2)
      • In 1953, the National Weather Service began using female names
      • In 1979, they began to use both men and women’s names
    • Important Hurricane Terms
      • A Hurricane Watch occurs when a hurricane is possible within 36 hours
        • The storm is being tracked to predict where it may hit
      • A Hurricane Warning is issued when it the storm is expected to hit within 24 hours
        • Evacuation may be needed
    • Hurricane Safety Tips
      • Know if the location you are in is a safe zone or whether evacuation may be needed
      • Protect windows and glass with plywood
      • Turn off utilities
      • Have a supply kit including first aid, water, canned goods, battery powered radio, blankets, etc.
      • After evacuation, do not return until it has been declared safe
