- Global wind patterns: Winds are named by the direction from which they blow. The globe is encircled by six major wind belts, three in each hemisphere.From pole to equator, they are the polar easterlies, the westerlies, and the trade winds. All six belts move north in the northern summer and south in the northern winter.cean Gyre: The fact that the westerlies and trade winds blow in opposite directions and that the continents prevent water from circling the globe contributes to the formation of circular ocean currents, clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.

What are flora and fauna? Global winds are dependent largely on the large difference in temperature between polar and tropical regions. Global warming heats the poles faster than the tropics, thus redu … cing the temperature difference. Exactly how global winds would change as a result is hard to predict.

What are the trade winds? The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree belt. As the wind blows to about five degrees north and south of the equator, both air and ocean currents come to a halt in a band of hot, dry air. This 10-degree belt around Earth's midsection is called the Inter-Tropical Convergence Zone, more commonly known as the doldrums. Intense solar heat in the doldrums warms and moistens the trade winds, thrusting air upwards into the atmosphere like a hot air balloon. As the air rises, it cools, causing persistent bands of showers and storms ...

- Since the Earth has little forces that tend to slow the spin, the winds of the jet stream provide enough force against the atmosphere of the Earth that the Earth will continue to spin, thus creates the balance for the earth through gyroscopial force.

- A prevailling wind is defined as a wind that blows predominantly from a single general direction.(). Global Wind Patterns are important because they distribute and circulate heat from the equatorial regions to the polar regions by convection. Think of these winds as the Earth's heating and air conditioning system. Notice these winds become deflected and appear to curve as a result of the Coriolis Effect.

Earth Science for Kids Global winds are created by both the spin of the Earth (Coriolis effect) and the differences in temperature between the equator and the polar areas. These winds are often grouped together as trade winds, easterlies, and westerlies. Trade winds - Trade winds occur near the equator and flow from either the north or south towards the equator.

- Solar heating of the atmosphere, differential heating of water and land masses, rotation of the Earth and the Coriolis effect it causes are the sources of global wind patterns.

Weather systems & patterns Air masses. These global wind patterns drive large bodies of air called air masses. Air masses are thousands of feet thick and extend across large areas of the Earth. The location over which an air mass forms will determine its characteristics. For example, air over the tropical ocean becomes exceptionally hot and humid.

- As the trade winds blow warm surface waters away from the west coast of continents, cold, nutrient-rich water is drawn to the surface. © 2011 Nature Education All rights reserved. Just as Earth's rotation creates the prevailing winds, it creates surface currents within the oceans. Under the influence of the trade winds, surface waters near the equator flow from east to west.

What Causes Global Winds? While local wind patterns appear to change from day to day at times, there is a global pattern of winds called the general circulation. The surface winds that move across the hemispheres are split up into three different wind belts.

wind As warm, moist air rises along the equator, surface air moves in to take its place, creating the trade winds. Some of the air that descends at the two tropics moves away from the equator, creating the westerlies. The eastward and westward movement of these wind patterns is caused by the Earth's clockwise rotation.

The Coriolis Force & Global Wind Systems The Environmental Literacy Council. The Coriolis Force & Global Wind Systems. The air in the Earth’s atmosphere moves from high pressure to low pressure. On a rotating body such as the Earth, the air turns to the right—counterclockwise—in the Northern Hemisphere and to the left—clockwise—in the Southern Hemisphere.

- While the Earth's rotation plays a role in wind and ocean currents, it is a somewhat indirect one. The primary factor that affects the formation of winds is differences in atmospheric pressure, caused by differences in incoming solar radiation (insolation).

- Major wind systems, the trade winds, monsoons. Major wind systems. The incident solar radiation, the distribution of the continents and the oceans, the rotation of the Earth and the land elevation all affect the climate. Most of the solar radiation falls in the Equatorial region.

Local Winds Good examples of local winds are sea breezes and land breezes, and mountain and valley breezes. Local winds cover very short distances. Global Winds. Global winds are really large air masses that are created mainly as a result of the earth’s rotation, the shape of the earth and the sun’s heating power.

- Global Wind Patterns wind belts of the general circulation. The global wind pattern is also known as the general circulation and the surface winds of each hemisphere are divided into three wind belts: 1  Polar Easterlies: From 60-90 degrees latitude. 2  Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies).

Atmospheric Forces Atmospheric Forces. Principle. Wind speed and direction respond to pressure gradient forces that exist between high and low pressure areas. In the Northern Hemisphere and because of the rotation of the earth, winds circulate in a clockwise fashion around areas of high pressure and in a counter-clockwise manner around regions of lower pressure.

Trade winds The trade winds are the prevailing pattern of easterly surface winds found in the tropics, within the lower portion of the Earth's atmosphere, in the lower section of the troposphere near the Earth's equator.rade winds originate more from the direction of the poles (northeast in the Northern Hemisphere, southeast in the Southern Hemisphere) during the cold season, and are stronger in the winter than the summer.

Trade Winds Trade Winds. Trade winds were introduced in Chapter 1 (Global weather patterns) as the equatorward blowing part of the Hadley cell. Because many cruising boats spend a lot of time in the trade wind region, some more detailed information is given in this chapter.

General Circulation of the Atmosphere General Circulation of the Atmosphere body. The circulation of wind in the atmosphere is driven by the rotation of the earth and the incoming energy from the sun. Wind circulates in each hemisphere in three distinct cells which help transport energy and heat from the equator to the poles.The winds are driven by the energy from the sun at the surface as warm air rises and colder air sinks.he warm surface conditions result in locally low pressure. The warm air rises at the equator producing clouds and causing instability in the atmosphere. This instability causes thunderstorms to develop and release large amounts of latent heat.

- The greenhouse effect is the trapping of heat by gases in the atmosphere. ▶ Earth’s curvature causes different latitudes to receive less or more intense solar energy. The unequal distribution of the sun’s heat on Earth’s surface results in three main climate zones: polar, temperate, and tropical.▶ Unequal heating of Earth’s surface also causes winds and ocean currents. Winds and currents move heat and moisture through the biosphere. Weather and Climate 1.HAT I KNOW SAMPLE ANSWER: The global climate is affected by how much sunlight reaches Earth. SAMPLE ANSWER: The global climate is shaped by many factors, including solar energy, latitude, and the transport of heat by winds and ocean currents. SAMPLE ANSWER: Some organisms are predators. Others are prey.
