Why is it windy in spring?

This has to start with the formation of the wind. 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. In cold places, the air is heavy and the pressure is high; In warm places, the air is light and the air pressure is low. Air flows from high pressure to low pressure. This airflow is the wind. Spring is the transitional season between severe winter and midsummer. The cold and warm air is very active, so there are often strong winds.

The north wind appears most frequently in spring. This is because the cold air in the north is still very strong in spring and keeps going south, while the ground is heating up quickly because of the increasingly intense solar radiation. As a result, a relatively strong cold air sinks and warm air rises. Because the high-altitude wind is usually much stronger than the ground wind, the enhancement of up-and-down convection increases the ground wind speed and forms a strong north wind.

Wind is a natural phenomenon caused by air flow, which is caused by solar radiation heat. Sunlight shines on the earth's surface, causing the surface temperature to rise, and the surface air to expand and become lighter and lighter. After the hot air rises, the cold air with low temperature flows in horizontally, and the rising air falls down because it gradually cools and becomes heavier. Because the surface temperature is high, it will heat up the air, and this airflow will produce wind.

Scientifically speaking, wind often refers to the horizontal motion component of air, including direction and size, that is, wind direction and wind speed; But for flight, it also includes vertical motion components, so-called vertical or ascending and descending airflow. Strong winds can move objects and their directions (mass of matter). The wind is very fast.
