Wind Currents Are Generated Due to Uneven Heating Flashcards
1) What are Wind Currents?
A current of air, sometimes of considerable forces, moving generally horizontally from areas of high pressure to low pressure.
How or which the way wind blows or lies.
Hottest region?
Equator
1)
Regions close to the equator get maximum heat from the Sun. The air in these region gets warm. The warm air rises, cooler air moves.
2)
These winds blow towards equator from north to south.
3)
At the poles (about 60 degrees), the air is colder than that at latitudes
4)
Wind circulation is set up from the poles to warmer latitudes.
\1) EASTERLIES-POLES TOWARD EQUATOR
2) WESTERLIES - WEST TO NORTH TOWARDS EQUATOR
Uneven heating of land and water
In summer, near the equator the land warms up faster and most of the time the temperature of the land is higher than that of water in the oceans
1) The air over the land get heated and rises. This causes the wind to flow from the Oceans towards Lands. This is called as MONSOON WINDS.
HERE COLD AIR IS TAKING PLACE
MY
2) In winter, the direction of the wind flow gets reversed, it flows from land to the ocean.
WARM AIR GOES TO OCEAN
COLD AIR - LAND.
3) THE MONSOON WINDS CARRY WATER AND RAIN.
WHAT ARE TRADE WINDS
steady winds blowing from east to west above and below the equator Winds 1) Permanent 2) Monsoon 3) Trade
