The polar (arctic) climate zone occupies the ice caps of the planet. The temperatures are negative all year round. In the South hemisphere this climate zone occupies the all territory of Antarctica and in the North hemisphere occupies the Arctic ocean. The conditions of life are exceptionally hard. Because of this reason, these areas are unpopulated. For example in Antarctica people can be found only in the research bases, but they don’t live there all year around.
The subarctic area is transition climate zone between the temperate and polar climate zone. It occupies the area around and beyond the Arctic Circle. This climate zone is wide spread almost only in the North hemisphere because of the missing of mainland, in these latitudes, in the South hemisphere. The ocean in this area in the South hemisphere, strongly modify the subarctic climate.
The temperate climate zone occupies large territories of our planet, mainly in the North hemisphere. It occupies big parts of North America (USA and Canada), Europe and Asia. In the South hemisphere it has limited spreading. It can be found in the southern most parts of South America, Tasmania and the South island of New Zealand. In the conditions of temperate climate we can see, that there are four different seasons – winter, spring, summer and autumn.
Subtropical climate is the most bearable for the people. It occupies the territories between the 30-th and 40-th parallel, but as very other rules and this has its exception. Usually the subtropical climate zone has long, dry and hot summer, short, mild and wet winter and very short transition seasons (spring and autumn). During the summer months this climate zone is influenced by tropical air masses. Through the winter months is absolutely possible the formation of snow cover.
