Will the typhoon12m wild waves cause major natural disasters?

This typhoon is typhoon 10 in 2020, which was named? Poseidon super storm. It has spread to Japan, South Korea, North Korea, China and some Russian regions. According to the latest report, a typhoon? Poseidon is moving northward, passing through South Korea and East Korea, and reaching Jilin Province and Heilongjiang Province in China. The good news is that Poseidon gradually weakened with its movement, changing from a strong typhoon to a typhoon and finally degenerating into an extratropical cyclone.

Affected by the typhoon, there will be strong convective weather such as heavy precipitation, lightning and strong wind in eastern China, especially in northeast China, and hail weather may occur in some areas and surrounding waters. In addition, storm surges may occur in coastal cities. These are direct disasters caused by typhoons. In addition, the secondary disasters of typhoons should not be underestimated. For example, frequent heavy precipitation may cause geological disasters such as mountain torrents, landslides and mudslides, and floods may occur in some areas with high probability.

According to the statistics of China Meteorological Bureau, four typhoons landed in Chinese mainland in the first three quarters, two fewer than the same period of many years (six), but in terms of intensity, Typhoon No.9 was super strong? Li Qima? This is the fifth strong typhoon that landed in Chinese mainland since 1949. Compared with the average value of the same period in recent five years, the direct economic losses caused by typhoon disasters are more 10%, and the number of deaths and missing persons due to disasters is reduced by 25%.

Not only that, the typhoon crossing the border will also bring ecological damage and epidemic situation. For example, a storm surge in a coastal city not only caused direct economic and personnel casualties such as destroyed construction farmland and missing population, but also caused land salinization due to coastal erosion and seawater intrusion, which was a problem that had to be faced later. The erosion of the ground by geological disasters such as rainstorm and debris flow is almost devastating. In particular, the underground drainage pipeline system in most cities in China is not perfect, which is prone to urban waterlogging. In addition, after the flood, it is easy to have an epidemic. These are all problems left over from the typhoon and must be solved.
