The main performances of Meiyu front on the weather map are as follows

Meiyufeng's performances on the weather map mainly include:

Meiyu front refers to the front formed by the intersection of warm and humid airflow in the south and dry and cold airflow in the north. Cyclone convection at the intersection of cold and warm air is very active, which is prone to heavy precipitation. Therefore, on the weather map, the Meiyu front often appears as a clear diagonal line, marking the location where the north-south airflow meets. In addition, Meiyu front will also produce obviously different meteorological processes, such as thunderstorms, showers and strong winds. Therefore, it is necessary to monitor and warn in time.

Mei Yufeng's performance also includes:

Meiyu front is an important sign of climate change in summer, which generally appears from mid-June to early July. Due to the hot and humid climate in the south and the dry climate in the north, the Meiyu front formed by them often stays in the south, leading to continuous rainy weather and the risk of flooding. Therefore, it is necessary to strengthen the monitoring and prevention of Meiyu front.

On the cause of Meiyu front:

Meiyu front is formed by the intersection of weak cold air in the north and warm and humid air in the south in Jianghuai area. In this process, two kinds of air produce convection at the intersection, which leads to large-scale precipitation.

When the cold air in the north moves to the south, it will meet the warm and humid air in the south, and then the two will interact. The air in front of the cold air is gradually influenced by the hot and humid air in the south, and the warm and humid air will also be suppressed by the cold air, which will make it rise to form clouds and then form precipitation.

In addition, the movement of the Pacific subtropical high will also affect the formation of Meiyu front. When the Pacific subtropical high moves southward, the warm and humid air flow in the south will be strengthened, which can further strengthen the formation of Meiyu front.

Generally speaking, the formation of Meiyu front is the result of many climatic factors, and all factors need to be considered comprehensively to predict the activity and influence of Meiyu front.

On the weather map, the moving speed of Meiyu front is generally slower than that of cold and warm fronts, accompanied by obvious precipitation process. Therefore, the rainfall area and rainfall intensity can be predicted in time through the weather map. Generally speaking, the appearance of Meiyu front is of great significance to the climate change in the north and south and the summer rainfall, so it is necessary to monitor and forecast in time to ensure the safety of people's lives and property.
