Diagram Of Trade Winds. A diagram illustrating columbus first route to the new world in red and the trade winds he used to get there in black. The air completes the cycle and flows back towards the equator as the trade winds.
Secondary winds occur in many locations throughout the world. Trade winds westerlies and easterlies are different types of primary wind. But the coriolis effect diverts to the right hand side any large fluid displacement in the northern hemisphere and that creates a belt of high pressures at rough.
Secondary winds are winds that change their direction in different seasons.
The easterly trade winds are driven by a surface pressure pattern of higher pressure in the eastern pacific and lower pressure in the west. Trade winds these are permanent winds flowing from east to west. These are extremely steady winds blowing from sub tropical high pressure areas 30n and s towards the equatorial low pressure belt. Secondary winds are also known as seasonal winds and periodic winds.
