Trade winds and countertrade

In this case, air flow would move at a specific direction: from the equator, the heated masses heading to the pole. And from the pole, already cooled air would move toward the equator. The weather would be more monotonous: the rains fell in the same place, the winds were blowing in the same direction. Furthermore, our planet rotates continuously. On top of this rotation warm currents from the equator do not start to move north and northeast, and about thirty degrees north and south are strictly from west to east. For this reason, in the vicinity of this latitude accumulate large air masses. Part of the air falls to the earth's surface. Here he captures and streams, which move from the poles to the equator. Thus the image of constant winds, trade winds. In the northern hemisphere they move from northeast to southwest. The British called the trade winds trade winds as they blow all year round in the same direction. In the days of sailing fleet seamen all over the world, knowing the constant trade winds, enjoy them while swimming in tropical latitudes. . But there is also a counter-trade. These air currents are a continuation of the trade winds, which reached the equator, rise up and turn toward the pole. Trade winds and counter-trade constitute a kind of aircraft wheel on which is supported by continuous air circulation between the equator and tropics. The work of this "machine" is continuously supported by the sun. If the excess heat of the sun over the equator has ceased to exist - would cease to exist by trade winds and countertrade.
