Can anyone explain me what are prevailing winds?

the prevailing winds are the direction the wind blows most of the time and during most of the year. This has a significance on e.g. the shoreline geography and weather patterns.
The equator is a warm place. Air rises then condenses and it rains. Here is where you find the equatorial rain forests.
The poles are cold places. The air sinks, giving place to high pressures.
If it was not for the earth rotation and the Coriolis effect, air would then move to and from the equator and the poles. But the Coriolis effect deflects the air to the right in the northern hemisphere. The air that rises over the equator builds then two belts of high pressure at roughly latitudes 30 N and 30 S.
Between those and the polar regions, two front of air masses of different temperature exist at roughly latitudes 60 N and 60 S. Warmer air climbs over colder one and that creates again two belts of low pressures.
Knowing that, in the northern hemisphere, the air turns clockwise around a high pressure, and counter-clockwise around a low one, you have roughly the prevailing winds around the globe.
Along the northern polar front, you'll find the Westerlies and that is what the answer above refers to.
