When a typhoon may land, it will suddenly stop raining. What can a sunny day be?

When the typhoon may land, it will suddenly stop raining and the sun is shining, which may be the phenomenon of entering the eye of the typhoon. When the typhoon reached the central area with a diameter of tens of kilometers, the wind dropped rapidly, the rainfall stopped, and a partially cloudy sky with sunshine during the day and stars at night appeared.

When the typhoon is cut horizontally, we can see that there are three obviously different areas, namely typhoon eye area, cloud wall area and spiral rain belt area from the center outward. Typhoon Eye Area: It's strange that the wind here is very light and the weather is sunny, with an average diameter of 40 kilometers.

Typhoon classification

In the past, China used to call the tropical cyclone formed on the tropical ocean surface above 26℃ a typhoon. According to its intensity, it is divided into six grades: tropical depression, tropical storm, strong tropical storm, typhoon, strong typhoon and super typhoon.

According to the notice of National Standard for Tropical Cyclone Grades (GBT 1920 1-2006) issued by China Meteorological Bureau, tropical cyclones are divided into six grades according to the maximum surface wind speed near the center:

Tropical depression, the maximum wind speed is 6 ~ 7, (10.8 ~ 17. 1 m/s);

Tropical storm with maximum wind speed of 8-9 (17.2-24.4m/s);

Strong tropical storm, maximum wind speed 10 ~ 1 1, (24.5 ~ 32.6m/s);

Typhoon, maximum wind speed 12 ~ 13, (32.7 ~ 41.4m/s);

Strong typhoon with maximum wind speed14 ~15 (41.5 ~ 50.9 m/s);

Super typhoon with maximum wind speed ≥ 16 (≥ 5 1.0m/s).
