Why did Typhoon Bavi bypass the three northeastern provinces?

Many people are teasing that Typhoon Bavi bypassed the three northeastern provinces? Eight dimensions? what's up Mi Bang Wei? My brother doesn't take the usual road. Under normal circumstances, typhoons that affect China mostly land in the southeast coast, and the main landing points are Guangdong, Taiwan Province, Fujian and Zhejiang. The number of typhoons in these four provinces basically accounts for more than 80% of the total number of typhoons in China. Even if a few typhoons can continue northward, they basically only affect Jiangsu and Shandong, and few typhoons can cross the Bohai Sea and land in the northeast.

And this typhoon? Eight dimensions? After it is generated, it briefly goes west, then directly goes north, and almost draws a straight line from north to south, as shown in the following figure. Eight dimensions? The generated detailed path can be clearly seen. Eight dimensions? The generated sea area is farther north and closer to land than most typhoons. Tropical storms and severe tropical storms were first generated in the eastern waters of Taiwan Province Province, but they did not weaken in the process of moving northward. Instead, they were further upgraded to typhoons and strong typhoons, and they kept the strong typhoon level all the way to the northern waters of the Yellow Sea. This situation is even more obvious? Eight dimensions? This route is unusual.

Why a typhoon? Eight dimensions? The different running routes are mainly related to the current subtropical high position. We all know that typhoon originated from tropical cyclone, which is a typical tropical low-pressure vortex, which is completely opposite to subtropical high. A low pressure and a high pressure are two completely opposite weather systems. Therefore, where there is subtropical high, it is basically impossible to generate typhoons. Even if the typhoon is generated near the subtropical high, the running path can only be close to the subtropical high, but not through it. Eight dimensions? The route is the result of sticking to the subtropical high.

The subtropical high began to affect China in February. From February to April, the ridge line of subtropical high is located at about 20 degrees north latitude, which affects the continuous rain in South China. In June, the ridge line of subtropical high rose northward to 20-25 degrees north latitude, and plum rains appeared in the middle and lower reaches of the Yangtze River. After July, the subtropical high crossed 25 degrees north latitude, and large-scale rainfall began in the Yellow River basin. In August, the subtropical high can reach north China and northeast China as far as the north, and it will weaken in September and begin to fall back to the south, which means that the current late August is the northernmost time period of the subtropical high.
