What wind is blowing? It will be wet.

When the wind blows to the south, the air becomes wet.

It is because the south of our country is an ocean, and the south wind is mixed with water vapor blowing from the sea, so it will be wet. Generally speaking, it refers to the southeast wind. Specifically, it means that the south wind blows in summer, but the north wind blows in winter. This is the meteorological feature of the northern hemisphere.

Because: hot air is lighter than cold air, and the heat will rise. In the range of the earth (including the atmosphere), the center of the earth is the hottest, and the farther away from the center of the earth, the lower the temperature, so the higher and colder it is, the hot air rises and the cold air sinks, which will produce air convection up and down.

On the earth's surface, the area perpendicular to the sunlight has the highest temperature and the fastest rising speed of airflow. As the air in this area rises, the surrounding air will be replenished from all directions, which forms the monsoon. When the sun is located in the northern hemisphere, the air in the southern hemisphere will be replenished to the northern hemisphere, which is the south wind in summer; When the sun is in the southern hemisphere, the air in the northern hemisphere supplements the past to the southern hemisphere, which is the north wind in winter. The southern hemisphere is mainly ocean, so the south wind is wet and warm, and there are many snowy mountains in the northern hemisphere, so the north wind is cold and dry.

The seasons in the northern hemisphere are opposite to those in the southern hemisphere. For example, the winter in China in the northern hemisphere is the summer in Australia in the southern hemisphere.
