Before and after Grain Rain

What happened to the weather around Grain Rain? After the solar term in Grain Rain, the rainfall increased and the humidity in the air gradually increased. In southern China, poplars are in full bloom, willows are falling, cuckoos are crying at night, peonies are blooming, and cherries are ripe. Natural scenery informs people that it is late spring. Grain Rain is in the late spring, which means that spring is coming to an end and summer is coming. The large-scale invasion of cold air into the south is rare, but the cold air activities affecting the north will not stop.

Grain Rain is the most windy solar term in many places in the north, so it is often the most prone to dust. April is the month with the highest frequency of sandstorm weather in China, the temperature is obviously higher than that in March, and the soil is dry and loose. The air layer is unstable, the upper wind drops, and the frontal cyclone is active, which is easy to cause strong winds and dusty weather.

For the south, there is generally no shortage of rain in Grain Rain, especially in South China. Once cold air meets warm and humid air, it often forms long-term rainy weather and frequent convective weather. Remind Jiangnan, South China and other places to pay special attention to local disastrous weather such as thunderstorms, hail, strong winds and tornadoes. At present, South China has entered the pre-flood season, so it is necessary to pay attention to short-term heavy rainfall, strong convection and other weather.
