Changes before and after typhoon transit

Typhoons are often accompanied by strong winds and heavy rains. Before the typhoon crossed the border, the weather was uncertain, but it could be sunny or rainy.

Climate change will have a certain impact on the northward movement of typhoon landing sites, but it is still too early to draw such a conclusion for a typhoon process, such as "Lichima". Judging whether the change of typhoon intensity is related to climate change depends on data quality, data density, data sources and research methods, and requires long-term observation.

Typhoons are often accompanied by strong winds and heavy rains; Before the typhoon crossed the border, the weather was uncertain, but it could be sunny or rainy. Typhoon is a very destructive and disastrous weather system, but sometimes it can also play a beneficial role in eliminating drought.

Extended data:

Before a typhoon crosses the border, if there is no strong convective weather, it is often southerly. After the typhoon hit, the wind direction changed to southeast wind or east wind, bringing a lot of water vapor, increasing the cloud cover and gradually lowering the cloud base.

If the weather is fine before crossing the border and the air pressure is high, especially in the area controlled by subtropical high, the air pressure will start to decrease when the typhoon crosses the border. Because the typhoon is a cyclone weather system, the closer it is to the center, the greater the pressure. If a place is lucky enough to enter the eye of the typhoon, the air pressure will increase.
