Regarding this, what causes trade winds?

The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree "belt." The sinking air triggers the calm trade winds and little precipitation, completing the cycle.

Also Know, what happens to the trade winds during La Nina? During La Niña conditions, the easterly trade winds near the equator get even stronger than they usually are. Stronger winds push surface water into the western Pacific. Meanwhile, cool water from deeper in the ocean rises up in the eastern Pacific.

Also to know is, how does global warming affect trade winds?

They are driven by warm air rising along the equator and the rotation of the Earth. Another piece of research suggests that when the trade winds are strong they drive more heat into the deep Pacific ocean, which brings cooler water to the surface and has a cooling effect to global surface temperatures.

How does El Nino affect winds?

El Niño is the periodic warming of water in the Pacific Ocean every few years. El Niño also affects wind shear, which is when air currents at a lower altitude blow in a different direction from winds higher in the atmosphere. Strong wind shear makes it harder for hurricanes to form.
