Today (May 13), the south finally ushered in the day of "Great Washi". It's not the rain, but the rain is resting and the sky is clear, and I can finally wash the clothes and sheets that are about to become moldy!
△ Judging from the cloud map, during the day today, most places on the mainland will be sunny and dry.
In the next few days, the precipitation in most parts of the country will still be weak, and Jiangnan and South China will also usher in a 5-6 day rain interval, and the sunshine will be online. However, due to the influence of easterly winds and topography, there will be continuous rain in southwest Guizhou, eastern and southern Yunnan, western Guangxi, Hainan Island and other places in the next two days, generally moderate to heavy rain, local or current heavy rain.
This wave of precipitation is characterized by strong surface weakness. Because the warm and humid airflow is not strong, the overall intensity of rainfall is not large, but in Yunnan, Hainan and other places, single-point convection may be stronger, and it is not excluded that there will be heavy rainfall, and the small partners in the above areas should not be underestimated.
The southern friends must cherish the rare "business" sunshine these days, because a new round of heavy rainfall will appear again this weekend.
According to the medium-term forecast of the Central Meteorological Observatory, from the 18th to the 20th, there will be a moderate to heavy rain process in Jianghan, Jianghuai, Jiangnan, South China, Sichuan Basin, Guizhou, Yunnan and other places, with heavy rain in some areas, and heavy rain in southern Jiangnan and northern South China.
△ Precipitation forecast for the next 10 days in the mainland.
Moreover, this round of rain will also affect the north, when there will be light to moderate rain in the eastern part of Northwest China, North China, Northeast China, Huanghuai and other places, local heavy rain and may be accompanied by strong convective weather such as short-term thunderstorms and strong winds.
The occurrence of this round of heavy rainfall may be related to the outbreak of the summer monsoon in the South China Sea, so its strength should not be underestimated. As it stands, the South China Sea summer monsoon is likely to break out around mid-May, and the monsoon-driven rainfall will be much more intense than the usual warm and cold frontal rainfall. Generally speaking, the outbreak of the summer monsoon in the South China Sea will promote the process of the rainy season on the mainland to a certain extent, for example, the "dragon boat water" in South China began to appear after its full-scale outbreak every year.
The rain in the south has taken a break for the time being, but the warming in the north has not stopped a little. It is expected that this week, the temperature in the north will continue to hit new highs amid fluctuations, and there are mainly two waves of temperature highs, and one is warmer than the other.
During the day today, temperatures in the north hit the first wave highs. As of 16 o'clock, the highest temperature in Hohhot, Beijing, Tianjin, Shijiazhuang, Lanzhou, Zhengzhou and Jinan has refreshed new highs this year, of which Beijing's 31.9 °C is also the first time this year to hit the 30 °C mark.
Two days after tomorrow, a wave of cold air from the easterly path will "flash" to cool down, temporarily interrupting the current process of 30°C northward expansion. Among them, tomorrow, under its influence, there will be a cooling of 6~14 °C from the north of North China to the west of the Northeast; The day after tomorrow, as the cold air moves eastward and southward, the cooling will affect most of the northeast and Huanghuai to Jianghuai, and the drop will also be 6~14 °C.
In large cities, on the 15th, the maximum temperature in Taiyuan will drop from 33 °C on the 14th to 25 °C; Zhengzhou will also drop from 34°C on the 14th to 26°C.
After the cooling, the rebound in the temperature in the north will be more violent. From the 17th to the 18th, the sunny and hot weather will reach its peak, and the North China Plain may usher in the first high temperature weather process this year. Among the big cities, Taiyuan, Tianjin, Shijiazhuang, Xi'an, and Zhengzhou are all expected to usher in the first high temperature of the year during this period. Everyone should be prepared for the hot summer weather, this year seems to be a little earlier than usual, and the hot summer is really coming this time! (China Weather Network)
