How to treat the power of Typhoon Bavi?

According to the agricultural situation dispatch of the Ministry of Agriculture and Rural Affairs, after typhoon Bawei entered China, its duration was short and its intensity was weak, causing crops such as corn and rice to lodging in sporadic plots in Liaoning, Jilin and Heilongjiang provinces, but it did not cause large-scale farmland water accumulation and large-scale lodging of crops. The affected area is obviously smaller than expected, and the impact on autumn grain production is generally limited, with average power.

At about 8: 30 am on August 27, 2020, Bawei landed on the coast of North Pyongan Road near the border between China and North Korea. When landing, the maximum wind force near the center 12 (35 m/s), and the lowest air pressure in the center is 970 hectopascals. At 10 in the morning, it weakened into a strong tropical storm, and its center was still located in North Pyongan Road of Korea, that is, 40. 1 degree north latitude and 124.8 degree east longitude. The maximum wind force10 (28m/s), and the lowest air pressure in the center is 985 hectopascals.

Typhoon is a kind of tropical cyclone. Tropical cyclone is a low-pressure vortex that occurs on the surface of tropical or subtropical ocean, and it is a powerful and profound "tropical weather system". In China, tropical cyclones in the South China Sea and the Northwest Pacific are divided into six grades according to the maximum average wind speed near the center of the bottom layer, and those whose wind reaches 12 or above are collectively called typhoons.
