Why does it always rain in Guangdong this year?
First of all, the South China Sea summer monsoon was stirred in advance. According to the forecast of East Asian summer monsoon circulation by the National Center, the South China Sea summer monsoon will break out earlier in 2022 than in previous years, and the third season will start in May (May11-May 15), while previous years usually start in the fourth quarter of May. This directly led to South China entering the flood season ahead of schedule.
The South China Sea summer monsoon is one of the important monsoons that affect the weather in China. After it erupts, the airflow carried by the monsoon will move northward. For us, this means that the southwest warm and humid water vapor carried by the airflow will enter the south of China in an all-round way, making the south of China enter the flood season.
If the summer monsoon is normal, the dragon boat water should erupt at the end of May, but it is normal for the summer monsoon to break out early this year. And in this way, by June, the rainfall may gradually weaken. ?
Secondly, the Asanni storm recently formed in the Bay of Bengal did not land in the Indian area on the west side as expected, but stayed in the same place. This makes it provide a steady stream of water vapor for the warm and humid air flow, which makes the dragon boat flood and rainstorm have an increasing trend on the basis of previous years. ?
Finally, the cold air from north to south is more abundant and arrives earlier than in previous years, which not only promotes the early outbreak of dragon boat water, but also adds "a handful of materials" to the rainstorm. ?
Rainstorm prevention measures
During the rainstorm, residents must take preventive measures. First of all, it is best not to go out, pay attention to the weather through weather forecast and weather mobile APP, and be prepared for the extreme weather that may occur in heavy rain; Secondly, electricity is destined to be used indoors to prevent conductive damage caused by water leakage.
Residents living in rural areas or low-lying areas should always be alert to flood disasters, and if necessary, they can pile sand bags and silt at the door and build protective walls. If the flood exceeds expectations, you can choose to move to higher places such as upstairs. Friends who are still driving outside during the rainstorm should pay more attention and try to avoid low-lying areas. Once the water level is found to be wrong, they should get off and move to higher ground.
