Wind and rain usually appear together. What's the connection between them?

Wind and rain occur at the same time, usually more obvious in summer. Sometimes it's sunny in the morning, and suddenly there is a strong wind in the afternoon, and then it will rain heavily. This kind of weather is generally called. Strong convective weather? The main reason is the strong vertical movement of air. At this time, the atmosphere is in an unstable state, and small water droplets will gradually become raindrops, and then the high-altitude airflow can no longer support the weight of water droplets, and finally become rain.

1. The formation of wind is mainly the result of air flow. When a cloud blocks the sun, the land below will be affected. At this point, the air will start to cool, resulting in a change in pressure. The area of the cloud is not big enough to cover all the sun. At this time, another piece of land and the covered land formed two different areas: high pressure and low pressure. When air flows from high pressure to low pressure, wind is formed. When the air moves strongly vertically, the wind will drive the small water droplets to change, and the slowly condensed small water droplets will become large water droplets.

2, the formation of rain The ground constantly absorbs the heat of the sun, which will lead to an increase in the overall temperature and a decrease in density. When the density is low, the atmosphere becomes unstable, and objects with low density will start to move upward. Like oil and water, oil tends to float on it. The rising wet airflow will make the small water droplets start to condense into water droplets. Once the airflow can't bear the weight of water droplets, water droplets begin to fall. Eventually, strong convective weather will be formed, and strong winds with showers will bring a little coolness to the hot summer. However, this kind of weather, the area is often very small, maybe about ten kilometers, or even smaller.

3. It usually appears in summer. This kind of weather is more common in summer, such as spring and autumn, and it appears less. The main reason is that the temperature is too high in summer, which will make the land absorb enough heat and reduce the density rapidly. In this way, the vertical rising speed of air will be accelerated, forming strong convective weather. In spring and autumn, the land can't absorb too high temperature, so it forms less times.
