The wind changes direction twice a year.

Winds that change their direction twice a year are monsoons. This property of these winds is explained by the change of seasons on the ground. In summer, the mainland heats up much faster than the ocean. An area of ​​low pressure is created over the mainland, and air currents are directed from the ocean to land. Summer monsoons rush from the ocean to land, they carry cool air. Winter monsoons, on the contrary. The ocean keeps warm for a very long time, and the mainland quickly cools. Air currents rush from the mainland to the ocean, into an area of ​​low pressure.
Therefore, in regions where monsoons are frequent (for example, the south of the Far East), dry and frosty winters and warm, but very rainy summers.
