Wind Currents Large-scale wind systems of the atmosphere, such as the westerlies, doldrums, polar easterlies, and trade winds
●
Westerlies- The (Prevailing)Westerlies are the weather movements that happen in the Northern Hemisphere and are responsible for the weather in U.S and Canada
●
Doldrums-A belt of calm and light variable winds near the Equator is called Doldrums. It is also known as low pressure zone, where winds disappear for number of days or weeks.
●
Polar Easterlies-The polar easterlies are the dry, cold prevailing winds that blow from the high-pressure areas of the polar highs at the north and south poles towards the low-pressure areas of the polar fronts between 60 and 90 degrees north and south
●
Trade Winds- Winds that blow steadily from east to west and toward the equator. he trade winds are caused by hot air rising at the equator, with cool air moving in to take its place from the north and from the south.
