The correct answer is the following.
Drag the names of the prevailing winds to the areas where they form in the Northern Hemisphere.
On the top, polar wind. In the middle, westerlies, on the bottom, trade winds.
The polar wind is the wind that comes from the North Pole, specifically, from the polar regions of the magnetosphere of the planet. Polar wind results from the interaction of the atmosphere of the earth and the Solar wind. The prevailing winds in the middle latitudes that come from the west to the east are called westerlies. The opposite, from east to west, are called trade winds. Some scientists call them easterlies, in opposition to the westerlies.
