Factors causing destructive power of typhoon

1, strong wind

Typhoon is a huge energy pool, and its wind speed is above 17m/s, even above 60m/s. According to the measurement, when the wind reaches 12, the wind pressure per square meter on the plane perpendicular to the wind direction can reach 230kg.

2. Heavy rain

Typhoon is a very strong rainfall system. When the typhoon lands, the rainstorm center can drop 100 to 300 mm, or even reach 500 to 800 mm a day. The floods caused by typhoons and rainstorms are the most dangerous disasters. Typhoon rainstorm is strong, flood occurs frequently, spreads widely, and is fierce and destructive.

3. Storm surge

The so-called storm surge means that when the typhoon moves to the land, due to the typhoon's strong wind force and low air pressure, the sea water accumulates strongly in the direction of the coast, the tide level rises sharply, and water waves come to the coast. The storm surge of a strong typhoon can raise the coastal water level by 5 to 6 meters.
