Typhoon Haigos landed in Zhuhai. Why do typhoons "prefer" Guangdong?

The preference of typhoon landing is not aimed at Guangdong, but depends on the comprehensive effect of many factors. However, Guangdong is indeed more vulnerable to typhoons than other provinces, which is caused by the following reasons:

1. Geographical factors: Guangdong has the longest coastline in China, so it is easier for typhoons to "target" Guangdong. Even if typhoons are generated in other places, they are often attracted by the coastline of Guangdong, which in turn affects Guangdong.

2. Circulation situation: Around June, the atmospheric system in East Asia was located to the south, and the subtropical high was also located to the south. At this time, typhoons can easily land in coastal provinces with low latitudes, including Guangdong. From July to September when typhoons are active, the subtropical high is basically located in the north of South China, and South China is located in the south of the subtropical high. At this time, the turning airflow around the subtropical high can easily "guide" the typhoon to South China.

3. Climatic characteristics: Guangdong belongs to monsoon climate zone, and summer is affected by monsoon. A large amount of water vapor transport and low-level convergence are beneficial to the formation and strengthening of typhoons.

4. Geological conditions: The soil and geological conditions along the coast of Guangdong also have some influence on the typhoon landing. For example, the Pearl River Delta region is low-lying, with poor drainage and dense river networks, which increase the risk of floods caused by typhoons.

Although Guangdong is vulnerable to typhoons, it does not mean that all typhoons will land in Guangdong. The moving path of typhoon is determined by many factors, including but not limited to the position of subtropical high, the direction of monsoon, the earth's rotation force, geostrophic deflection force and so on. Therefore, although Guangdong "prefers" typhoon landing, it is not absolute.
