Can I travel during the Dragon Boat Festival holiday?, There are still thunderstorms today, a very typical "atypical plum rain" affecting Shanghai lightning | process | thunderstorms
Since last Saturday night, rainstorm has witnessed torrential rain. The Shanghai Meteorological Department stated that a very typical "atypical plum rain" is affecting Shanghai. When can we bid farewell to the rain as the Dragon Boat Festival holiday approaches?
It rained heavily in Shencheng last weekend, with rainstorm in some areas. From 8:00 to 20:00 on June 18, within 12 hours, the accumulated rainfall in Chongming reached 48.2 mm, reaching the level of rainstorm in the whole region, of which 158.2 mm in Zhixin Town of Chongming was the largest, reaching the level of heavy rainstorm. The cumulative rainfall in the central urban area is 30.2 millimeters. As of press release, the blue warning signal of rainstorm and the yellow warning signal of thunder and lightning in Shanghai, as well as the four level response action of flood control and typhoon prevention in the city, are still being maintained.
However, this rain has not ended and will continue today. According to the forecast of Shanghai center Meteorological Station on the 18th, there will be short-term heavy rainfall of 20-40mm in one hour from the evening of the 18th to the morning of the 19th. Urban emergency departments should strengthen prevention, prevent urban waterlogging caused by heavy rainfall, and do a good job in drainage and flood prevention in low-lying and easily flooded areas.
The forecast shows that there may still be strong convective weather such as short-term heavy rainfall, lightning, thunderstorms, and strong winds in Shencheng today. Due to the pressure of rainwater, the highest temperature is 26 ℃, and the overall feeling is damp. The violent plum blossoms with strong rainfall and flashes of wind and lightning seem to be not in line with the gloomy and rainy rainy season of Huangmei in our impression.
According to experts from the Shanghai Meteorological Bureau, "violent plum rain" is a characteristic of atypical plum rain that has appeared in Shanghai in recent years. In the past 20 years, the characteristics of plum rain in Shanghai have changed, with a decrease in average plum rain, longer rainy seasons, an increase in the proportion of abnormal rainfall years, and a weakening of the sustainability of plum rain precipitation. These are all manifestations of Meiyu becoming atypical. The typical features of the "atypical" plum rain are process precipitation, high temperature, and strong thunderstorm weather.
The National Climate Center predicts that after the onset of the plum blossom season this year, strong convective weather in China will become active, with frequent occurrences of short-term heavy rainfall, thunderstorms, strong winds, tornadoes, hail, and other severe convective weather. These are all changes that have occurred in the context of global warming.
In the past week, the northern region has experienced intense heat, sweeping over 2 million square kilometers and breaking records for geothermal activity; The rainfall in the south is surging, and the Meiyu relay in Jiangnan is carrying the dragon boat water in South China. One wave has not calmed down, and another wave has risen... Seeing the Dragon Boat Festival holiday approaching, can we still travel smoothly?
As for Shanghai, this wave of rain will temporarily stop from Wednesday, so everyone can hurry up and wash it. And the highest temperature will also rise to 30 ℃ to 32 ℃, and a sense of stuffiness will appear around noon. Starting from Friday, as the rain belt rises northward again, the cloudy and rainy weather in Shanghai increases again. It is expected that the next more obvious precipitation process will occur on the weekend.
The Central Meteorological Observatory reminds that areas such as the middle and lower reaches of the Yangtze River have entered a period of concentrated heavy rainfall. In the next ten days, some areas in southern Jiangsu and Anhui, western Zhejiang, central and northern Jiangxi, Hunan, central and northern Guangxi, southern Guizhou, and western Yunnan will have a cumulative precipitation of 130 to 180 millimeters, with some areas reaching over 200 millimeters; The precipitation in most of the above-mentioned areas is 50% to more than twice that of the same period in the year. From a safety perspective, it is recommended that everyone avoid traveling to scenic areas such as mountainous areas and valleys where there has been frequent rainfall recently, and not go to undeveloped and open "wild scenic spots" without safety guarantees.
