World Climate

The climate of our planet is exceptionally various. There are many factors which mould it. For example the distance from the equator (the latitude), elevation above sea level, relief, nearness or remoteness of the seas and oceans, as well as many other factors. As much as bigger is the distance from the equator, so much the angle of sunbeam falling is acuter. This mean, that the bigger latitudes receive more insignificant warmth. As direction from the equator to the poles, we can follow equatorial, subequatorial, tropical, subtropical, temperate, subarctic and polar (arctic) climate zone.

Besides the enumerate climate zones, there is one more that is specific with it’s change of the temperature not in direction north – south, but in altitude. Every one of these zones can be very different.

On the other hand the most attractive areas get into the subtropical climate zones, because it is considered to be the most pleasant, healthy and bearable.

The relief, indicate strong influence on the climate. It could play the part of barrier into the moving of large masses of air, if there are high mountain ranges.

In case of flat relief we can sea the formation of climatic corridor, what afford the opportunity for freely moving of the large masses of air.

In depending on the temperature of the ocean stream we can distinguish warm and cold currents. In nearness to the warm currents the climate is more humid in comparison with the lands in nearness to the cold streams.

In the case of cold currents is conversely – less vapours and insignificant precipitations. This is one of the main reasons for the formation of deserts namely in closeness of cold sea and ocean streams.
