"Plum Blossom" is the first typhoon to land in China with the intensity of strong typhoons this year, and it is also a typical autumn platform.

The power of the autumn typhoon cannot be underestimated. Typhoon autumn refers to the typhoon generated in the three months from September to November. From the perspective of quantity, autumn typhoons are not less than typhoons in summer. At the same time, it also has three major characteristics of strong intensity, southern landing position, and cold air.

According to the Zhejiang Meteorological Observatory, due to the influence of "plum blossoms", Ningbo, Zhoushan, eastern Shaoxing, northern Taizhou and other places in Zhejiang descended to rainstorms. From 20:00 on the 11th to 16:00, 91 townships (streets) in Zhejiang Province exceeded 200 mm, of which 16 towns (streets) exceeded 300 mm.

Why does the rainfall come fiercely? Xu Yan, chief forecast at Zhejiang Meteorological Observatory, said that the reason for a large amount of precipitation was the "train effect" caused by this typhoon. With the rotation of the spiral cloud belt of the typhoon, a large amount of precipitation cloud group passed through the same area, like the train of the train across the same section of the same section of the rails, resulting in a large precipitation, precipitation and intensity in the same area.

Experts said that the periphery of the typhoon and the cold air, as well as the influence of the typhoon, caused continuous heavy precipitation in Ningbo and Shaoxing. In addition, when you meet the tide of astronomy, the three encounters of wind and rain will bring great pressure on the city's drainage and easily cause urban waterlogging. The inverted seawater can cause waterlogging in some urban and rural areas, and the people need to minimize their out.

At the same time, the main precipitation area of ​​"Plum Blossoms" has basically overlapped the typhoon of "Xuanlan Nuo". The strong precipitation in the short period of time may cause geological disasters such as floods and mountain landslides. Special attention is needed.

Ma Xinyu, chief expert of Zhejiang Meteorological Service Center, said that "plum blossoms" had weakened slightly due to terrain friction after landing. "After the typhoon landing in Shanghai, the impact on the southern part of Zhejiang has gradually weakened, but we still have to be vigilant on the impact of the wind and rain generated by the second landing." Ma Xinyu said.

According to the Central Meteorological Observatory, due to the influence of "plum blossoms", Zhejiang, Shanghai, Jiangsu, Shandong and other places encountered storms. During the day on the 15th, there were still heavy rainstorms in the heavy rain in the northern part of Huzhou, Hangzhou, and the wind weakened significantly from the afternoon. The meteorological department reminds that the coast and inland need to do a good job of prevention.
