What is the difference between the formation conditions of persistent rainstorm and strong convective weather?
In the same way, the hot air near the ground rises under the buoyancy, forming a rising hot and humid airflow. When it rises to a certain height, the water vapor contained in the air will condense into water droplets due to the temperature drop. When water droplets fall, they are picked up by stronger updraft, and so on. Small water droplets begin to accumulate and integrate into large water droplets until the upper air cannot support their weight, and finally they fall into the rain. This is why thunderstorms in summer are not as rainy as spring rains in Mao Mao, and the water drops are bigger.
Of course, the physical process of the formation of various severe convective weather is not exactly the same, which is closely related to the influence of dynamic and thermal effects of the underlying surface. Moreover, strong convective weather is based on large-scale weather systems, which affects or determines the generation, development and movement of small and medium-scale weather systems. For example, during the Meiyu period, a wide range of cold and warm air meet to form a Meiyu front rain belt, which will produce heavy rain in some areas if it is matched with favorable conditions such as topography.
