Super typhoon "Lichima" is coming soon. Why do typhoons mostly come in summer?

Recently, many cities have been put on alert because of typhoons. It is reported that this super typhoon "Lijima" will attack Zhejiang and Shanghai, so Zhejiang and Shanghai have also taken corresponding protective measures to better cope with this disaster. In fact, people who observe carefully will find that typhoons always seem to happen in summer, but they never seem to happen in winter. Why do typhoons mostly come in summer?

Summer creates conditions for typhoons. First, let's look at what a typhoon is.

In the past, we often called hot gas cyclones above 26 degrees Celsius typhoons, but later, with more and more types of typhoons, in other words, we learned more about typhoons, so we stopped calling them typhoons. However, typhoon belongs to a tropical weather system, and its formation requires conditions. High temperature and high humidity are important conditions for the formation of typhoons, and it is precisely in summer that important conditions are created for this. This is why typhoons often appear in some areas, while they almost never appear in some areas, because those areas often do not have the necessary conditions to help form typhoons.

The necessary condition is high temperature. Generally speaking, typhoons often occur in the North Atlantic and Indian Ocean. Moreover, our area in Zhejiang and Shanghai is also a place where typhoons often occur.

The first super typhoon "Dai Wen" landed in Zhejiang since the founding of the People's Republic of China.

Therefore, once the typhoon enters the high-latitude sea area and the temperature is not high, the main conditions for the formation of typhoon losses will gradually disappear. So typhoons rarely occur in winter.

Although the probability of typhoon in winter is very small, the measures to be taken need to be done well.
