In which climatic zone of Eurasia there are especially many climatic regions? What is the reason for such a variety?

It is quite possible to guess that in moderation. Because this climatic zone is the largest in area, stretches along the whole of Eurasia and is a wide strip. The diversity of climatic zones is seriously affected by the complexity of the relief and the winds blowing from as many as three oceans: the Atlantic, Pacific and Arctic.

The Atlantic Ocean noticeably affects the climate of Western Europe, where it is cool in summer, and in winter there is no such frost as in Russia. The composition of the western transport of air masses includes the air flowing down the outskirts of the Azores anticyclone. There, along the polar and arctic fronts, cyclones migrate, which arise in the Icelandic depression. When air from the Atlantic moves eastward, it dries up and becomes continental. And in the Far East, in temperate latitudes, winters are dry and cold, and summers are humid and warm, because the climate there is monsoon.
