Why are three typhoons landing in Zhejiang and Shanghai this year preferring East China?
This is the first typhoon to land in Zhejiang this year. There was no typhoon last year. According to statistics, from 1949 to 2017, there were 41 typhoons landing in Zhejiang, of which August was the most concentrated month, with 18 typhoons landing and 23 in the rest months.
This year, typhoons prefer East China. In less than a month from late July to now, three typhoons have landed in East China.
From the historical data, Jiangsu, Zhejiang and Shanghai are not the favorite places of typhoons. From 1949 to the end of August 2017, there were 49 typhoons landing in Jiangsu, Zhejiang and Shanghai, with an average of less than one per year. In contrast, Guangdong is the largest typhoon landing households, with 166 landing typhoons, 2 to 3 per year.
Why do typhoons prefer Jiangsu, Zhejiang and Shanghai this year? All of these are the subtropical high playing a leading role behind the scenes. Most of the typhoons affecting our country are generated in the Northwest Pacific Ocean, and most of the typhoons generated in this region are generated in the southern edge of the subtropical high and move along the periphery of the subtropical high. When the typhoon is located in the south side of the subtropical high, it will move westward under the guidance of the south by East airflow.
From the beginning of July to the first ten days of August this year, the subtropical high is abnormally northward and strong, and it is stable over North China, Northeast China, Huanghuai and other places in China. The coastal area of East China is on the south edge of the subtropical high, which increases the probability of "zhongzhao" typhoon in Jiangsu, Zhejiang and Shanghai.
