Why is it windy in spring?

It is windy in spring because the temperature changes greatly. When the sun shines on the earth's surface, due to the latitude difference, the heating degree varies from place to place, so there is a difference between cold and warm. Cold and warm air meet to form strong convective weather. In cold places, the air is heavy and the pressure is high; In warm places, the air is light, the air pressure is low, and the air flows from high pressure places to low pressure places, so there are often strong winds.

Why does the strong wind come in spring?

Running water, air and iron wind

According to the climatic data, the maximum monthly average wind speed in China appears from February to April in spring.

Warm and cold alternate, and the atmosphere is active.

We can think of air as flowing water. In fact, air is blown from a place with high pressure to a place with low pressure. This horizontal movement of air is wind. Spring is the adjustment period of atmospheric circulation. Whether in the south or the north, the weather system is active and the atmosphere moves frequently, so there will be more winds. If the air pressure difference is large at this time, there will be windy weather.

Radiation Enhancement and Latitude Difference

Due to the latitude difference, the heating degree in the north and south is different. After the vernal equinox, the sun shines directly in the northern hemisphere, and the solar radiation reaching the surface increases. In the south, the ground heats up quickly and the atmosphere expands when heated. At high latitudes, however, the solar radiation is less, and the ground temperature rises slowly, which leads to the pressure gradient force between the north and the south becoming larger and prone to northerly winds.
