Is Shaoxing greatly affected by typhoons?

Shaoxing is mainly affected by typhoons in the following two aspects.

I. Weather

Shaoxing is cloudy to cloudy today (July 27th), with showers or thunderstorms at night, moderate to heavy rainfall and local heavy rain. It will be cloudy to cloudy with showers or thunderstorms tomorrow, with moderate rainfall and partial heavy rain. There are thunderstorms in some areas mentioned above, which may be accompanied by short-term heavy rain. The southeast wind is 3-4, the gust is 5-6, and it will increase to 6-8 tomorrow.

Causes of typhoon formation

1, with pre-existing disturbance.

Typhoons are all developed from the pre-existing tropical depression disturbance. According to China's statistics, the tropical cyclones in the western Pacific-South China Sea region come from four initial disturbances in intertropical convergence zone, accounting for 80% ~ 85%; East wind wave, accounting for about10%; The cut-off low pressure in the long wave trough at middle and high latitudes, or the cold vortex at high altitude, accounts for about 5%; Baroclinic disturbance accounts for less than 5%.

2. Warm ocean surface, with seawater temperature higher than 26.5℃

The temperature and humidity of the upper and lower atmosphere in tropical oceans are mainly determined by the sea surface water temperature. The higher the SST, the higher the temperature and humidity of the lower atmosphere, and the more obvious the potential instability. Typhoons are formed on the warm ocean surface with SST ≥ 26 ~ 27℃. Generally speaking, the global tropical ocean surface meets this condition all year round, and only the SST in the equatorial southeast Pacific Ocean is ≤ 26.5℃ all year round, which is the main reason why there are no typhoons here.
