In general, there are two types of winds. Those that are
local and those that go long distance over the earth. The winds on the seashore
are simple of local winds. During that daytime, the land gets heated , the air
above it rises, and cool wind take its place from the sea. At night, the land
is cooler then the sea, the hotter air above the sea rises up, and the cool
winds from the land take it palace. Thus, this is continue sly process. The
hottest place on the earth are around the equator. The air above is rises and
at certain latitudes, it gets cooled and comes down. The winds blowing towards
the equator are the trade winds and those blowing toward the poles are called
the westerly.
