Hibiscus

Seawater is warmed by the sun and evaporates, turning into water vapor. The south tropics are hot and can contain large amounts of water vapor in the atmosphere. Water vapor begins to rise while swirling counterclockwise, and an updraft is generated. The rising water vapor becomes water droplets in the cold air above, forming clouds. When a strong updraft is generated, moist air flows into it one after another, and the clouds eventually grow into cumulonimbus clouds.

Cumulonimbus clouds develop further and grow into typhoons (tropical cyclones). This is the mechanism of the generation of the typhoon. The typhoon blows and reduces the temperature difference between the north and the south. In other words, the heat wave will ease.

Typhoon No. 3 "Chaba" occurred in the South China Sea. In the future, it is expected to slowly move north and land on China. "Chaba" is derived from "Hibiscus" in Thai. Hibiscus is a shrub with a height of 2 to 5 m in the tropics and subtropics, but it is surprisingly not strong against the heat of a "hot day".
