What kind of plum rain does the south of the Yangtze River belong to?

Meiyu in Jiangnan area belongs to frontal rain type.

The summer monsoon blows from the ocean to the land, bringing rich water vapor. In winter, the wind blows from the inland high pressure area to the ocean, and its path moves from the high pressure area to the low pressure area. Summer monsoon and winter monsoon form a front when they meet in the middle and lower reaches of the Yangtze River, which leads to continuous rainy weather in this area.

The rainy season is characterized by continuous rainfall, high temperature and high humidity. This season's rainfall is usually more than other seasons and lasts longer. Because of the high humidity, people feel sultry and clothes are not easy to dry. At the same time, due to the long rainy weather, the air pressure is low, and sometimes there will be some slightly polluted weather, such as smog.

In the rainy season, the weather changes in Jiangnan are very complicated. Although the temperature is high this season, sometimes the temperature drops suddenly and the weather is extremely complicated. In addition, due to the long rainy weather, the humidity in the air is also high, which is easy to lead to some meteorological disasters, such as heavy rain and floods.

Type of rain:

1. Convective rain: Convective rain is rain caused by high ground temperature, which forms updraft, brings water vapor into the cloud and condenses into water droplets in the cloud. Convective rain usually occurs in the afternoon or evening in summer, with short rainfall time and high rainfall intensity.

2. Typhoon rainstorm: Typhoon rainstorm refers to the rainfall brought by typhoon. Typhoon is a tropical cyclone, which will bring violent storms during its movement. The rainfall intensity of typhoon rain is very strong, sometimes accompanied by strong winds, lightning and other weather phenomena.

3. Topographic precipitation: Topographic precipitation is rainfall caused by topographic obstacles, such as mountains and hills, where the airflow is forced to rise. The rainfall intensity in topographic precipitation depends on the height and shape of topographic obstacles, as well as the strength and stability of airflow.

4. Freezing rain: Freezing rain is a special form of precipitation, which usually occurs in winter. When the temperature is lower than 0℃, rainwater freezes on the ground or the surface of objects, forming ice crystals or ice layers. Freezing rain usually does not form water droplets, but falls to the ground like ice particles. Freezing rain will have a serious impact on traffic and communication lines.
