The document discusses the layers of the Earth's atmosphere and how global winds are formed. It notes that the atmosphere has four layers, with weather occurring primarily in the lowest layer called the troposphere. It then explains that air rises in warm regions near the equator where pressure is low, and descends in cold areas like the poles where pressure is high, driving global wind patterns from areas of high pressure to low pressure. However, winds are deflected by the Coriolis force and actually blow clockwise out of high pressure areas and anti-clockwise into low pressure areas. Stronger winds occur with a larger pressure difference between high and low pressure areas.

The Intertropical Convergence Zone (ITCZ) is an area encircling the Earth near the equator where the trade winds of the northern and southern hemispheres meet. The ITCZ forms a belt of clouds and thunderstorms driven by solar heating. It marks the ascending branch of the Hadley cell and brings wet weather, while the descending branch causes dry conditions at the horse latitudes. The location of the ITCZ varies seasonally as it follows the sun's zenith point over land and shifts more subtly over oceans according to sea surface temperature distribution.
Natural disasters by Melvin Muscat, 3.04
Hurricanes are tropical storms characterized by strong winds and heavy rain that form over warm ocean waters. Tornadoes are rotating columns of air that extend from the base of thunderstorms to the ground. Volcanoes form at boundaries where tectonic plates meet or separate, allowing magma and gases to escape the Earth's crust. Tsunamis are a series of powerful ocean waves caused by earthquakes, landslides, or volcanic eruptions that can cause devastating damage to coastal areas.
AIR MASSES AND FRONT
The document discusses air masses and fronts. It defines air masses as large bodies of air with uniform properties that form over land or water surfaces. There are four main types of air masses classified by their region of formation: maritime/continental and polar/tropical. Fronts are boundaries between unlike air masses. There are three main types of fronts: cold fronts, where cold air overtakes warm air; warm fronts, where warm air overtakes cold air; and occluded fronts, where a warm air mass is overtaken by two cooler air masses.
6.3 circulation cells
The document discusses the three main air circulation cells on Earth:
1) Hadley cells near the equator where hot air rises and spreads toward the subtropics, bringing high humidity, clouds, and rain with no winter.
2) Ferrel cells between 30-60 degrees latitude with distinct seasons and broadleaf/evergreen forests.
3) Polar cells where icy cold air descends and meets warmer mid-latitude air, suppressing precipitation and creating tundra and taiga biomes near the poles.
Weather
Global air circulation patterns are held to Earth's surface by gravity and heated by the planet. The Coriolis effect causes apparent deflections in moving air as seen from Earth's rotating frame of reference. Air pressure decreases with altitude due to the weight of air above, and wind occurs as air moves from high to low pressure areas. Air masses develop distinct characteristics over different surfaces and temperatures, influencing weather patterns as high or low pressure systems move across regions. Warm and cold fronts form at boundaries between air masses with differing temperatures and humidity levels.
Winds and Wind System
this presentation is all about different kinds of winds and wind system.. hope this will help you a lot in your studies :)
Winds grade 7
The document discusses three main factors that influence winds: winds, air pressure, and wind currents. It describes how air pressure is caused by the weight of air above a location, with low pressure areas having less atmospheric mass and high pressure areas having more mass. It also explains the global wind patterns caused by uneven heating between the equator and poles and over land and water, which creates the polar easterlies, westerlies, and trade winds wind belts in each hemisphere.
Geography; Jet Streams and Ocean Currents
Jet streams and ocean currents were discussed. Jet streams are fast flowing air currents found near the transition between the troposphere and stratosphere, and are caused by the planet's rotation and atmospheric heating. The main jet streams on Earth flow west to east. Ocean currents are directed movements of ocean water generated by various forces, and can flow for great distances, influencing climate patterns. Examples given were the Gulf Stream making Northwest Europe warmer, and the Humboldt Current cooling Peru.

Global circulation patterns of atmosphere
The global circulation of the atmosphere involves three main circulation cells in each hemisphere - the Hadley cell, Ferrel cell, and polar cell - that help transport heat from the equator to the poles. The Hadley cell extends from the equator to 30 degrees latitude and involves warm, moist air rising at the equator and sinking at 30 degrees, powering the trade winds. Between 30-60 degrees is the Ferrel cell, where prevailing westerly winds occur. The polar cell extends from 60 degrees to the poles and involves cold air sinking over high latitudes. Disruptions to these cells, like during El Niño, can significantly impact regional climates and agriculture.
General Circulation of the Atmosphere
Air Circulation models, three model cells, planetary & local wind are shown here with flexible example.
Global winds
Global winds are large air currents that circle the Earth and move air masses across long distances. They include the jet stream over North America, which flows from west to east between warm and cold air masses, and eight major wind types defined by their direction and location. Pictures show the global circulation patterns including the Hadley cells where air rises at the equator and sinks at 30 degrees latitude while rotating east or west.
CLIMATIC REGIONS
The document defines climatic regions as large areas that have similar climates. It describes five main climatic regions: the equatorial region near the equator which is very hot; the tropical region between the Tropics of Cancer and Capricorn; the desert region outside the tropics from 20-30 degrees latitude; the temperate region between the tropics and polar circles in both hemispheres; and the polar regions north of the Arctic Circle which have short summers and long winters.

Air Masses, Global Winds, and Fronts
This document discusses key concepts in meteorology including:
1. Meteorology is the study of atmospheric phenomena like weather and climate. Different types of atmospheric "meteors" include clouds, rain, fog, and rainbows.
2. Weather describes current atmospheric conditions while climate refers to long-term average conditions in an area.
3. Air masses form over large areas and take on the characteristics of those regions, like continental polar (cP) air masses which are cold and dry.
4. Global wind systems like the trade winds and prevailing westerlies circulate air globally due to the Coriolis effect from Earth's rotation. Fronts form where different air masses collide.
2019 tg atmosphere2 atmospheric circulation
The document discusses atmospheric circulation and weather systems. It explains that uneven heating of the Earth's surface causes pressure differences in the atmosphere which drive wind patterns. Key factors that determine winds include temperature, pressure, humidity, and the forces of pressure gradient, friction, and the Coriolis effect from the Earth's rotation. It describes global wind systems like the Hadley, Ferrel, and polar cells that comprise the general circulation. It also covers local winds, air masses, fronts, and storm systems like cyclones, thunderstorms, and tornadoes.
Cyclone and its types
Cyclones form due to rising warm air that cools and condenses to form clouds. If the air starts spinning horizontally over tropical oceans, it can develop into a tropical depression, storm, and eventually a hurricane or typhoon depending on location and wind speeds. Cyclones cause heavy rainfall, landslides, damage to infrastructure and homes, disruption to ecosystems and agriculture, and harm to human and animal life. Coastal areas need to prepare shelters and strengthen infrastructure to mitigate cyclonic damage.
Earth surface wind system ppt.
The document provides an overview of atmospheric circulation patterns and surface wind systems. It discusses three categories of atmospheric motion: primary, secondary, and tertiary circulation. Primary circulation includes the planetary wind system of trade winds, westerlies, and easterlies. The earth's surface wind system consists of four patterns - doldrums, trade wind belts, prevailing westerlies, and polar easterlies. Doldrums are located around the equator in low pressure. Trade winds originate from subtropical high pressure zones. Prevailing westerlies are located between 30 and 60 degrees latitude. Polar easterlies move out of polar high pressure towards subpolar low pressure.
Air pressure and wind system
This document defines key weather-related terms and describes various wind patterns and storms. It explains that wind is caused by differences in air pressure and can be measured using an anemometer. Monsoon winds are seasonal winds that bring rain from the sea to land. Thunderstorms often lead to cyclones and tornadoes, which are severe storms that can cause extensive damage. Sea breezes and land breezes are local wind patterns influenced by differing air temperatures over land and sea.
Fronts
Fronts are boundaries between two air masses of differing characteristics. There are four main types of fronts: cold fronts, warm fronts, occluded fronts, and stationary fronts. Cold fronts are steep boundaries where cold air overrides warm air, bringing precipitation. Warm fronts are more gradual, with light, continuous precipitation as warm air rises over cold air. Occluded fronts occur when a cold front catches up to a warm front. Stationary fronts have little or no movement as the air masses are parallel.
2019 tg atmosphere4 koppen
The document summarizes the Köppen climate classification system. It was developed in 1918 by Wladimir Köppen and is still widely used today. The system categorizes climates into five main groups (A, B, C, D, E) based on annual and monthly temperature and precipitation averages. Each group is further divided into climate types based on seasonal precipitation and temperature characteristics. The document provides detailed descriptions of the climate zones including tropical humid, dry, warm temperate, cold, and polar climates. It also notes vertical climate zonation with elevation in mountainous areas.
NATURAL DISASTERS
The document discusses several natural disasters including earthquakes, hurricanes, landslides, tornados, tsunamis, drought, volcanoes. It provides key details about the causes and characteristics of each type of disaster such as earthquakes being caused by shifting tectonic plates, hurricanes forming over warm ocean waters and rotating counterclockwise in the northern hemisphere, landslides occurring on steep slopes due to factors like rain or earthquakes, and volcanoes erupting when underground pressure becomes too great.
Notes - Air Masses, Fronts, Global Winds
Meteorology is the study of atmospheric phenomena including weather and climate. Weather refers to current atmospheric conditions while climate describes average conditions over time for a particular region. Air masses form over large areas and take on characteristics of that region, later influencing other areas as the air mass moves horizontally. Global wind patterns called zones transport air masses. Weather systems form as air masses with different properties interact, such as through fronts which occur at boundaries between air masses.
How Cyclones Are Formed
Cyclones form from thunderstorms over warm ocean waters above 26.5°C, which provide the necessary heat and moisture energy. They weaken rapidly over land or colder waters that lack these ingredients. There are two main types of cyclones - cold-core cyclones that form due to upper-level troughs, and warm-core cyclones that initially depend on storm-relative upper-level highs to strengthen. The six types of cyclones are polar, polar low, extra tropical, subtropical, tropical, and mesoscale.
Air mass
An air mass is a large body of air with similar temperature and moisture properties that can cover hundreds of thousands of square miles. Air masses originate over land or water source regions and take on the characteristics of the surface below over time. There are four main types of air masses defined by their source region in tropical or polar latitudes and whether that region is over land or water. When polar air meets warmer air over the United States, it causes the formation of the polar jet stream, a narrow belt of strong winds near the top of the troposphere that influences weather patterns and temperatures in the US.
Air masses (summary)
This document discusses air masses, which are large bodies of air that share similar temperature and moisture characteristics. Air masses originate over source regions and are classified based on the latitude and surface type of the source region. The weather experienced in an area depends on the characteristics of the prevailing air mass. The main air masses that affect North America are continental and maritime polar and tropical air masses.
Air masses and its types
This document discusses air masses and their types. It defines an air mass as a large body of air with similar temperature and humidity that forms in stable source regions. There are two main types of air masses - continental and maritime. Continental air masses originate over landmasses and are usually dry, while maritime air masses originate over large bodies of water and are usually moist. Specific continental air masses include tropical (cT), mid-latitude (cM), and polar (cP). Maritime air masses include tropical (mT), mid-latitude (mM), and polar (mP). Each air mass has distinct characteristics depending on its source region and how it interacts with terrain as it moves across regions.
Natural Disasters Topic 10 (Cyclones)
Cyclones are rotating storms characterized by inward spiraling winds surrounding a center of low pressure. They form over warm ocean waters when air rises and condenses. Due to the Coriolis effect, cyclones in the Northern Hemisphere rotate clockwise and counterclockwise in the Southern Hemisphere. Cyclones can have devastating effects through high winds, heavy rain, storm surges, flooding, and tornadoes. They are classified based on wind speed scales like the Saffir-Simpson scale. Regional names like hurricanes and typhoons are used depending on ocean basins.

Winds Air Masses Fronts
Uneven heating of the atmosphere causes warm air to rise and cool air to sink, generating wind as air moves from high to low pressure areas. The Coriolis effect causes objects in the northern hemisphere to be deflected to the right and objects in the southern hemisphere to be deflected to the left as the Earth rotates. Global wind patterns include trade winds near the equator, prevailing westerlies at mid-latitudes, and polar easterlies near the poles. Jet streams are fast winds in the upper atmosphere that can help or hinder airplane travel. Air masses originate over land or water and bring the characteristic weather of their source region when they move over new areas. Different types of fronts form boundaries between air masses
Airmass
An air mass is a large body of air with similar temperature and humidity characteristics that forms in stable source regions such as the subtropics or polar regions. There are five main air masses that affect Europe: tropical maritime (mild and moist), tropical continental (warm and dry), polar maritime (cool and moist), polar continental (cold and dry), and arctic maritime (cold and moist). Each air mass originates over a different source region and brings distinct weather conditions depending on its temperature and moisture content.
Land and sea breeze
During the day, the sea breeze blows from the sea to land as the air over the land warms up faster than the air over the water. At night, the land breeze blows from land to sea as the land cools down faster than the water due to the water's higher specific heat capacity, causing the air over the water to become warmer and less dense than the air over the land. The document defines and describes the sea breeze and land breeze patterns that occur daily as a result of the differing ways land and water absorb and release heat.
Settlement and urban growth
The document discusses the location and growth of settlements. It describes how early settlements were located based on factors like access to water, defensive positioning, and natural resources. It then explains how settlements evolve over time and take on different functions. The main functions of settlements discussed are administrative, defensive, mining, industrial, tourist, educational, religious, residential, port, market town, and route center. Larger settlements tend to be multi-functional. The document also introduces models of urban land use, including the Burgess and Hoyt models which describe concentric zones of land use radiating from the central business district.
Settlement Patterns
Settlement patterns can take various forms including dispersed, linear, and nucleated. Dispersed settlements involve scattered houses over a large rural area, often in hilly or flat lands. Linear settlements see grouped houses along roads, railways, coasts or rivers to benefit from transportation. Nucleated settlements center around a focal point like a road intersection, with houses clustered around this nucleus, potentially growing into market towns or urban centers over time.

Weather patterns in the phillipines
Weather patterns in the Philippines are influenced by factors like temperature, humidity, wind, pressure, and air masses. Two main air masses pass over the Philippines - a warm, humid air mass from April to October that brings rain and typhoons, and a cool, dry air mass from November to February that brings the dry season. The country is also affected by prevailing winds like the southwest and northeast monsoons. Different types of fronts can cause changes in weather as warm and cold air masses meet.
9th Grade Chapter 2 Lesson 4
The document discusses global patterns of atmospheric circulation. Uneven heating of the Earth's surface causes convection currents that drive major air movements. Rising warm air creates low pressure systems, while sinking cool air creates high pressure systems. The Coriolis effect causes winds to curve due to the Earth's rotation, creating large wind circulation cells and wind zones like the trade winds and prevailing westerlies in each hemisphere. Local winds like monsoons and sea breezes are also driven by uneven land and sea heating.

Air masses and fronts
- Air masses are large bodies of air with uniform temperature and moisture characteristics that form over source regions. The main types are continental polar (CP), maritime polar (MP), continental tropical (CT), and maritime tropical (MT).
- Fronts occur at boundaries between converging air masses. The main types are cold fronts, warm fronts, stationary fronts, and occluded fronts. Cold fronts bring strong winds and thunderstorms while warm fronts bring gentle rain.
- Frontogenesis is the formation of fronts while frontolysis is the dissipation of fronts. Mid-latitude cyclones form due to frontogenesis between air masses.
Air Masses and Fronts
Maritime tropical air masses form over warm waters and bring warm, moist air into parts of the United States. Continental polar air masses form over snow-covered northern Canada and bring cold, dry air into central and eastern portions of the country. When warm and cold air masses meet, fronts are formed. Cold fronts have steep slopes that can produce heavy precipitation like thunderstorms and hail, while warm fronts have more gentle slopes and cause lighter, longer-lasting precipitation from nimbostratus clouds. Occluded fronts occur when a cold front catches up to a warm front.
Chapter 2 Weather Su09
This document summarizes information about hurricanes, weather, climate, and atmospheric conditions. It discusses Hurricane Bertha in 1996 that caused damage in the Caribbean and eastern US. It then provides an overview of typical weather phenomena and how extreme events occasionally emerge. It describes how weather is recorded and climate is characterized. It explains that the troposphere is the lowest layer of the atmosphere. It discusses objectives to understand the lower atmosphere and how weather affects climate. It outlines factors that influence air temperature like solar radiation, water vapor, cloud cover, surface type, elevation, and air movement.
Climate
Climate is defined as the long-term weather patterns of a particular region, averaged over a period of 30 years. It is influenced by several factors including solar radiation, latitude, elevation, wind, ocean currents, and the amount of precipitation an area receives. Together these factors help determine the temperature and moisture levels of different parts of the world, which then influence the types of climates and ecosystems that exist in each region. As climate change causes rising global temperatures, many species are experiencing shifts in their natural ranges and changes to the timing of seasonal life cycles in order to adapt to the altering environmental conditions.
The Restless Atmosphere
The document discusses how the atmosphere and winds are created. It explains that the sun unevenly heats the Earth's surface, causing air to rise in some areas and fall in others. This difference in air pressure creates winds that blow from high to low pressure areas. It also describes how latitude affects temperature, with areas near the equator being warmer, and how the Earth's rotation causes air currents to bend into circular storm patterns.
FRONTS AND AIR MASSES.pptx
This document discusses air masses and weather fronts. It defines air masses as large volumes of air that form over source regions with uniform temperature and humidity. Air masses are classified by their region of origin and whether they form over land or water. Weather fronts mark the boundaries between air masses and can cause large temperature variations. The most common fronts are cold fronts, where cold air advances under warm air; warm fronts, where warm air rises over cold air; and stationary fronts, where fronts slow or remain in the same area for long periods. Occluded fronts occur when a cold front catches up to a warm front.
Wind [autosaved]
This document provides information about winds and the factors that influence them. It discusses:
- What causes wind including differences in air pressure from uneven heating of the atmosphere. Warm air rises creating low pressure areas and cool air sinks creating high pressure areas.
- The primary, secondary, and tertiary global wind systems. The primary circulation includes the trade winds and westerlies. Secondary winds include monsoons and cyclones/anticyclones. Tertiary winds are local winds.
- Features of different wind types like the doldrums, trade winds, westerlies, and polar easterlies. It also discusses monsoons, land/sea breezes, and valley winds.
Winds
The document discusses different types of winds and how they are caused. It explains that temperature variations between different regions of the Earth due to uneven heating from the sun lead to differences in air pressure and the formation of wind. Winds blow in three main circulation cells in each hemisphere - Hadley, Ferrel, and polar cells - helping to transport heat from the equator to poles. Primary winds include trade winds and westerlies that blow throughout the year between latitudes. Secondary winds change seasonally, like land and sea breezes. Local winds are influenced by local geographic features. Aeolian processes refer to how wind erosion, transportation, and deposition can shape the Earth's surface over time.
Geography chapter air class 7 notes
The document summarizes key aspects of air and the atmosphere. It describes the composition of the atmosphere, which is mostly nitrogen and oxygen. It also notes that the atmosphere is divided into five layers - the troposphere, stratosphere, mesosphere, thermosphere and exosphere. The first layer, the troposphere, extends from the Earth's surface to around 13 km and contains the air we breathe. Weather occurs within the troposphere, while climate refers to average weather conditions over a longer period of time. The document also discusses air pressure, winds, moisture, clouds, precipitation and the different types of rainfall.
Weather ms ppt 1997
Weather is the current state of the atmosphere. It can be gentle or fierce, bringing life or death. Various cultures have different names for weather phenomena like wind. Weather results from uneven heating of the Earth's surface, which causes warm air to rise and cold air to sink, driving global wind patterns. Local winds are caused by differences in land and sea temperatures. Air pressure, temperature, humidity, and wind speed all factor into weather conditions. Clouds form when water vapor condenses, and different cloud types signal upcoming weather. Weather maps depict fronts where air masses meet, indicating precipitation and storms.

Wind
- 1. Wind John Harris - Head of Geography - Radley College - UK [email_address] http://geography.radley.org.uk
- 3. The earth’s weather takes place in the lowest level called the Troposphere
- 4. Air rises over warm areas and sinks over cold areas Air rises in warm regions where pressure is low (convection) eg the tropics Air descends in cold areas where pressure is high (subsidence) eg the poles
- 5. Global winds Wind is the movement of air from regions of high pressure to regions of low pressure
- 6. Winds deflect! Winds do not blow directly from high to low pressure …. they get deflected by the Coriolis force
- 8. Wind speed! The bigger the difference in pressure (pressure gradient) the stronger the wind
