Why did it get very hot before the typhoon came?

Before the typhoon came, the weather became very hot for the following reasons:

1. Typhoon forms on the surface of tropical ocean, and the tropical ocean air mass it brings will release heat during the formation process, which will lead to an increase in temperature.

2. When a typhoon moves, it will rub with air, water vapor and particulate matter in the atmosphere to generate heat.

3. In the process of typhoon moving, due to the influence of Coriolis force and other factors, its path often changes, which will also lead to the increase of temperature.

4. The air pressure in front of the typhoon is relatively low, air compression will release heat, and the low air pressure will also promote the surrounding temperature to rise.

It should be noted that although the weather may become very hot before the typhoon, the typhoon itself will not directly lead to high temperature weather. In fact, before and after a typhoon crosses the border, it usually brings rainfall and cooling due to its strong wind and suction, which helps to alleviate the high temperature weather.
