17 Learning goal: How the of through the Earth s atmosphere, the Earth s, absorption and radiation of create patterns and Effect of Air pressure on Global winds Polar Easterlies (From 90 O to 60 O North/South) - Polar Easterlies can be found at the north and south poles and they are cold and dry because of where it is located, which is at high latitudes. This type of wind system forms when cool air, at the poles, and then s to the equator. in s of and to

18 Learning goal: How the of through the Earth s atmosphere, the Earth s, absorption and radiation of create patterns and Effect of Air pressure on Global winds Prevailing Westerlies (From 0 O to 60 O North/South) located in the 0-60 degrees latitude in the northern and southern hemispheres. They blow from South West in the Northern hemisphere and South East in the Southern. Sometimes called the "Roaring Forties" because the particularly strong westerly winds in the band between 0 and 50 degrees southern latitude. European ships making their return trip from North and South America would use the prevailing westerlies to put the wind at their back as they sailed back to Europe. in s of and to

19 Learning goal: How the of through the Earth s atmosphere, the Earth s, absorption and radiation of create patterns and Effect of Air pressure on Global winds Horse Latitudes (From 0 O to 5 O North/South) - Horse latitudes are a region where there is weak winds because of high pressure and decreasing dry air. The origin of the name Horse latitudes is that ships that needed wind power couldn't move on the calm water and the sailors threw the horses and cattle over the ship to save on provisions. in s of and to

21 Learning goal: How the of through the Earth s atmosphere, the Earth s, absorption and radiation of create patterns and Effect of Air pressure on Global winds Easterly Trade winds (From 5 O to 0 O North/South) - Easterly Trade winds move from North East in the Northern hemisphere and South East in the Southern. These form as air from the equator rises, it gets warmer and when it cools down, it comes back down to the equator. Trade winds get its name from its capability of blowing trade ships across the ocean, very quickly. By the 8th century the importance of the trade winds to England's merchant fleet for crossing the Atlantic Ocean had led to the name 'trade' or "(foreign) commerce" in s of and to

22 Learning goal: How the of through the Earth s atmosphere, the Earth s, absorption and radiation of create patterns and Effect of Air pressure on Global winds Intertropical Convergence Zone (From 5 O north to 5 O South) - The Intertropical Convergence Zone is also known as Equatorial Convergence Zone or the Intertropical Front. It forms when southeast and northeast trade winds converge in a low pressure zone, near the equator. It usually appears as a band of clouds and comes with thunderstorms, which are short but produce extreme amounts of rain. in s of and to

23 Learning goal: How the of through the Earth s atmosphere, the Earth s, absorption and radiation of create patterns and Effect of Air pressure on Global winds Doldrums (5 O north and south of the equator) - Doldrums are just outside of the Intertropical Convergence Zone. The name Doldrums originated from some sailor who noticed the stillness in the rising air and called it the "doldrums", which means depression or despondency. in s of and to
