Why do typhoons prefer Guangdong?

Every year, South China can't escape the fate of typhoon patronage, especially in Guangdong. So, why do typhoons prefer to land in Guangdong? What controls the route of the typhoon? Why Guangdong? There are many factors that affect the typhoon path. Let's answer why there are so many typhoons in Guangdong by analyzing the factors that affect the typhoon path.

The subtropical high covering the south of China is very strong. What is the relationship between typhoon and subtropical high? Probably: the arm can't twist the thigh. Typhoon can only be pushed westward by subtropical high. The southwest monsoon provides the typhoon with a northward movement. This is easy to understand. When the wind blows the leaves, which direction does the leaves drift with the wind? You know, only tropical oceans are places where typhoons are generated. The sea surface temperature there is very high, so that the lower air can fully accept the water from the sea surface.

It is also the place with the richest water vapor on the earth, which is the main driving force for the formation and development of typhoons. Without this motivation, the typhoon will dissipate even if it is formed. There is a certain distance from the equator, and the deflection force generated by the earth's rotation plays a certain role, which is conducive to the development of cyclone circulation and the strengthening of airflow convergence. Under these conditions, as long as there is a suitable trigger mechanism. When divergent air currents appear at high altitude or the trade winds in the northern and southern hemispheres meet slightly north of the equator, typhoons will form and strengthen in some tropical waters.

According to statistics, in tropical oceans, typhoons often occur in areas where the sea surface temperature exceeds 26-27℃. The subtropical high is located in the subtropical zone, which is one of the main weather systems that affect the summer weather in Chinese mainland. The moving path of typhoon is often affected by it, just like "the leaves are driven by the current". In general, if the offshore subtropical high is strong and stable, the typhoon will move along the normal path. The shape and intensity of subtropical high will change greatly when the auxiliary airflow is adjusted or changed, or when multiple typhoons appear at the same time. The typhoon path will also become abnormal. So there are many typhoons in Guangdong.
