Air Currents
Vocabulary:
-
Trade Winds: Trade winds are steady winds that flow from east to west between 30 degrees north latitude and 20 degrees south latitude.
Westerlies: Westerlies are steady winds that flow from west to east between latitudes 30 degrees north and 60 degrees north, and 30 degrees south and 60 degrees south.
Polar Easterlies: The polar easterlies are cold winds that blow from the east to the west near the North Pole and the South Pole.
-
Sea Breeze: Sea Breeze is the wind that blows from the sea to the land due to local temperature and pressure differences.
Land Breeze: Land Breeze is a wind that blows from the land to the sea due to local temperatures and pressure differences.

Local Winds
Sea and Land Breezes
Sea and land breezes normally occur always at an ocean shore. A sea breeze is wind that blows from the sea to the land due to local temperature and pressure differences. Land warms faster then water in sunny days; that makes cold winds in the ocean, and warm wind in the land which have different pressures. Later on, they create a a cool wind that blows from the sea onto land. Land breeze is exactly the same but at night. Land cools of more quickly then ocean at night. This will later create a land breeze that blows from the land towards the water.
Global Wind Belts
Global Wind Belts is how the wind moves on earth. Apparently, convection cells of air move from the equator to other areas. The warmer air from the equator goes to the top of the troposphere and then when its cooled it goes back to the equator. That creates a convection cell.
The Coriolis Effect
The coriolis effect is when earth's rotation causes moving air and water to appear to move to the right in the nnorthern hemisphere and to the left in the southern hemisphere. This effect and high and low pressure in the air create wind patterns, called prevailing winds.
Prevailing Winds
The Coriolis effect apparently creates trade winds, they are steady winds that flow from east to west, which are massive in size. When they reach at about 30 degrees north and south, the air cools and falls into the water. Then doldrums start to appear which are dangerous for humans in boats. There are also polar easterlies which are cold winds that blow from the east to the west near the North Pole and the South Pole.
Jet Streams
Jet streams are narrow bands of high winds that are near the top of the troposphere. These winds are gigantic and are very influential in weather because they carry cold and warm winds to other places like the tropics.
