Typhoon No.3 has a high probability of forming on July 30th. Where will China be affected?

According to central weather bureau's observation, there are some convective clouds in the Pacific Ocean, but they are too close to the Philippine Islands and land, so they may not develop and grow, and they may be dominated by tropical depression, and the possibility of rising into a typhoon cannot be ruled out. In fact, judging from the situation in previous years, typhoons usually landed in China in July, but not this year. This is the first time since July1that there was no typhoon in July. There was no typhoon in July this year, because the subtropical high continued to be strong and southerly, which inhibited the convection activity in the tropical western Pacific, which is the breeding ground of typhoons, so there were fewer typhoons in the western Pacific this year. But typhoon No.3 has not arrived yet, but it has been named Senlake.

So, what are the conditions for the formation of a typhoon? In fact, the formation of desk lamps generally requires the following three conditions:

The first condition is higher seawater temperature. Generally speaking, if a typhoon is to form, the sea surface temperature needs to be at least above 26℃;

The second condition is a certain geostrophic deflection. The geostrophic deflection force decreases with the decrease of geographical latitude and is zero in equatorial region, which is the reason why there is no typhoon in the ocean below latitude 5;

The third condition is that there should be an initial disturbance and an environment to strengthen the disturbance.

In short, as long as these conditions are met, a typhoon may form. So far, the waters near the Philippines are basically satisfied, but the equatorial convergence zone is not obvious enough, the organization is not strong, and it is too close to the land, and the water vapor supplement is not strong, which is not conducive to the integration and enhancement of typhoon embryos. Therefore, it is still unknown whether a typhoon can form. Once the No.3 typhoon "Senlake" is formed, there will be heavy wind and rain in the coastal areas of South China, which will also bring some relief to the high temperature and dry weather in the country. Of course, we should also pay attention to the sharp turn of drought and flood.

Judging from the current weather forecast, the typhoon will not land directly in Guangdong, and it is most likely to land in Fujian. Affected by the typhoon's huge circulating cloud system, there will also be typhoon rainstorm in Guangdong in the near future. A large area of shanghai dawn, some areas have heavy rain. It is expected that there will be a large area of moderate to heavy rain in eastern Guangdong and heavy rain in the southeast coastal areas. In addition to Guangdong, Fujian and Zhejiang coastal areas will also be affected by this typhoon, resulting in moderate to heavy rain.

So, before the typhoon comes, how should we guard against it?

First, we must pay attention to listening to the weather forecast and keep abreast of typhoon trends.

Secondly, we must prepare enough food, clean water and medicine.

Third, be sure to check whether the doors and windows are closed and put away the flowerpots or other items on the balcony.

Fourth, we must check whether the facilities such as circuits, gas and fire fighting are safe.

Fifth, it is necessary to clean the drainage pipeline in time to keep the drainage unblocked.

In short, as long as these measures are taken, there is no need to worry about typhoons.
