Atmospheric motion of quasi-static front in South China

The atmospheric motion of the quasi-static front in South China is as follows:

The quasi-static front in South China is one of the common weather systems in South China in spring, and its atmospheric movement has the following characteristics:

Frontal formation: The quasi-static front in South China is mainly influenced by warm and humid airflow in the southwest and cold air in the southeast. Frontal is formed in South China, usually located in the first line of Guizhou, Hunan, Jiangxi and Guangdong.

Frontal movement: The frontal movement of the quasi-static front in South China is regular, generally moving northward, but the movement speed is slow and it is easy to stay in a certain area.

Atmospheric motion: Near the quasi-static front of South China, the atmospheric motion is more complicated. Generally speaking, cold air goes south to the north of the front, and warm and humid air flows north to the south, and the two meet to form the front. Near the front, the weather is changeable, and there are often rainy, windy, cooling, smog and other weather phenomena.

The influence of front on the weather: the quasi-static front in South China has a great influence on the weather in South China in spring. When the frontal position is south, rainy and humid weather is easy to appear in the south, and the temperature is low; When the front is northward, the southern region is prone to sunny and dry weather, and the temperature is relatively high.

Formation mechanism: the formation mechanism of quasi-static front in South China is complex, involving the influence of many factors such as thermal difference between land and sea and topography. Generally speaking, the interaction between southwest warm and humid airflow and southeast cold air is one of the main reasons.

Weather forecast: Due to the uncertainty of the movement and influence of the quasi-static front in South China, more detailed meteorological observation and numerical simulation techniques are needed for the weather forecast of the quasi-static front in South China. In meteorological forecast, it is often necessary to comprehensively consider the pressure, temperature, humidity, wind speed and other factors to predict the position and moving trend of the front.

In a word, the quasi-static front in South China is one of the common weather systems in South China in spring, and its atmospheric movement is complex and uncertain. It is of great significance to study it deeply to improve the accuracy and refinement of weather forecast.
