Typhoon in Guangzhou 15
As the king of wind in 20021year, the peak value reached above 17, and it was also the first "autumn typhoon" to reach this state in 20021year. Once it lands, it will definitely have a great impact, so it is lucky not to land. However, successive visits by typhoons still have a certain impact on the development of China's coastal areas. After all, it's very troublesome to always need wind and rain.
Typhoon's Path Shift Many people say that this year's "Magic Capital" enchantment came into effect, so this 202 1 wind king came and turned. We know that this has nothing to do with the "magic capital enchantment", but the turning flow has changed.
However, as it continued to approach Japan, a new typhoon embryo appeared in the Pacific Northwest with the code of 97W. Many people say it may be Typhoon Dian Mu on 202 1 15, right? Let's have a look.
97W is a typhoon embryo located in the eastern Philippines, with wind speed 15KT and central pressure 1006hpa. From the simulation of GFS, it is indeed possible to develop a new typhoon this year.
Next, 97W will continue to move westward, and it is expected that a "central" typhoon embryo will be formed in the South China Sea. It is expected that the pressure may reach 997 hectopascals on September 23rd. According to the pressure value, it is possible to name it, and at this time, the typhoon embryo of 97W is very close to Vietnam.
Affected by development, it may soon weaken to a low pressure state. For the 97W, there is indeed room for change. In the future, when we are close to Vietnam, we will look forward to the development of Hainan Island and Beihai in China. So there is still great uncertainty about how to change.
At the same time, we can only say that Typhoon Dian Mu may be generated this year 15, but from the trend, this possibility is quite low, and it is most likely to bring wind and rain climate change. This is the general situation and the only new typhoon embryo in the northwest Pacific. The route of European Numerical Center (EC) is the same and complicated, but it is close to Vietnam.
Therefore, on the whole, 97W still has a lot of room for change. It can only be said that it may develop into Typhoon Dian Mu 15 this year, but the probability is low, so we can only continue to observe it. Climate change in land areas is more complicated.
The main problem is rainfall. According to the forecast of the Central Meteorological Observatory, there will be a large-scale rainfall in China from the night of September 17 to the 20 th (Mid-Autumn Festival), and there will be a wave of large-scale rainfall from west to east in northwest, southwest, Jianghan, north China and northeast China.
As for rainfall, this round of rainfall can be regarded as rain in the north and south, and the rainfall intensity is large and wide, and the rainfall period coincides with the Mid-Autumn Festival holiday, which requires special attention.
We can see from the supercomputer, for example, on September 19, a "cyclone" appeared in North China, and at the same time, the subtropical high in the northwest Pacific was very strong, which continuously transported warm and humid airflow to the north, just forming a gradient of "45 degrees", which provided a basis for the sufficient increase of rainfall.
After that, the cyclone will move to the northeast, and the "cold and warm airflow" forms the basis of rainfall, so it is a compound rain with greater intensity. There is rain, local heavy rain and heavy rain in the provinces (urban areas) above the north and south 10. This is the general situation.
Conclusion The climate of 202 1 is really complicated. Whether it happens or not, we are worried about climate change. This year, the whole world is the same, and there are many strong extreme climate patterns, reminding human beings that climate change is becoming more and more complicated, and it is the same in spring, summer, autumn and winter.
