Little knowledge of meteorological science: how did typhoons form?

Typhoon is the direct sunlight on the tropical sea surface, which makes the sea water temperature rise, evaporate to form water vapor, and the surrounding cold air flows in and then rises again, and so on. This is what we call a typhoon. And the harm that typhoon brings to people should not be underestimated.

One is strong wind, the wind speed is above17m/s, even above 60m/s. With such strong wind, ships at sea can easily sink to the bottom of the sea, easily causing casualties and damaging buildings on land. Therefore, strong winds are extremely destructive.

2. Rainstorm: When the typhoon lands, the rainstorm center can drop 1000m-300 mm a day. Several typhoons can even produce 1000 meters of torrential rain, which is the most dangerous natural disaster with strong rainstorm intensity, high frequency of floods, wide spread and great destructive power.

3. Storm surge: When the typhoon moves to the land, due to the typhoon's strong wind force and low air pressure, seawater will accumulate strongly along the coast, resulting in the surge of tidal level, and the waves will press against the coast like an avalanche, which can raise the water level along the coast by as much as 5 to 6 meters, which will not only cause coastal erosion, seawater intrusion and land salinization, but also produce extremely high tidal level when the storm surge meets astronomical high tide level, leading to tidal overflow and breakwater.
