China Weather News from today (8th) night to 10th, due to the eastward movement of the high-altitude trough, there will be a large-scale strong convection weather in Beijing, Tianjin, Hebei and other places. At the time of the college entrance examination, China Weather.com has specially counted the time when major cities may be affected. Candidates and parents must bring rain gear and pay attention to safety.
Since June, frequent strong convective weather in the north and uneven distribution of heavy rainfall
Recently, strong convective weather in the north has frequently appeared. On July 6, scattered heavy rains or torrential rains occurred in central Heilongjiang, western and eastern Jilin, southeastern Inner Mongolia, northern Hebei, southern and northwestern Beijing, and southeastern Shandong. Harbin, Heilongjiang Hesuihua local heavy rain (100 ~ 132 mm). Rainfall has obvious short-term strong rainfall characteristics, and the areas of heavy rainfall are also scattered.
Among the provincial capital cities, taking Beijing as an example, since June this year, the cumulative precipitation of the Observatory Station in the southern suburbs of Beijing has reached 86.4 millimeters, which is nearly three times that of last year (29.9 millimeters). Among them, it fell within one day on July 6. In addition, short-term strong winds of magnitude 6 or higher occurred in most areas on that day, and small hail fell in Fangshan, Changping, and Daxing.

In addition, from the distribution area, the heavy rainfall in Beijing is also unevenly distributed. Due to the topography, the local and western rainfalls in the west and north are extremely heavy. In one day, there were local heavy rainfalls or even heavy rainfalls close to the magnitude of heavy rains. Like Changping, the cumulative rainfall of the site since June has reached 181.1 mm, far exceeding the normal period of 110.52 mm.
Three days from now, North China will welcome a wide range of thunderstorms, college entrance examination candidates need to pay attention to safety
Zhang Juan, a meteorological analyst at China Weather Network, said that from tonight to the 10th, North China will experience a rainfall process, and some areas of Beijing, Tianjin and Hebei will experience moderate to heavy rains or even heavy rains. There will be moderate to heavy rain. On the night of the 8th, as the high-altitude trough moved eastward, and the warm and humid airflow from the low-altitude to the south increased, rainfall in Beijing, Tianjin and Hebei increased. From the 9th to the 10th, due to the maintenance of the high-pressure dam over the northeast area, the high-pressure dam can be understood as a belt-shaped high-pressure system, which blocks the footsteps of the high-altitude trough to continue to move eastward, resulting in the slow movement of the cold vortex and deepening the development of the cold vortex, resulting in North China and other places Thunderstorms occur frequently.
The main rainfall period occurs from the night of the 8th to the 9th. Among them, Shanxi and other places will be the first to be affected today, and there will be scattered thunderstorms. At night, the rainfall will extend from Shanxi to Hebei, Beijing, Central Inner Mongolia and other places. There will be small to moderate rain, heavy rain in some areas, and local heavy rain, accompanied by strong convective weather such as lightning, short-term heavy rainfall, and hail. From the night of the 9th to the day of the 10th, there will be scattered thunderstorms in Beijing, Tianjin, Hebei and central Inner Mongolia.
In large cities, during the college entrance examination, Beijing, Tianjin, Shijiazhuang, Taiyuan, and Hohhot will be affected by rainfall, especially Beijing and Tianjin this year, the college entrance examination lasts four days (7-10). From the perspective of specific impact periods: 8th-9th, Taiyuan, Hohhot; 9th, Shijiazhuang; 9th-10th, Beijing, Tianjin.
In addition to lightning, strong winds, and hail, the impact of short-term heavy rainfall on travel should not be underestimated. Candidates and parents in the above areas must be prepared. In addition to paying attention to the weather forecast in a timely manner, how should we properly prevent it? What should we pay attention to when traveling?
1. When it is exposed to thunderstorms outdoors, avoid hiding from high-voltage power lines and isolated tall buildings, trees, flagpoles, etc., and do not stand in open highlands or under trees to avoid rain or electric shocks.
2. Before going out, check the closure of the engine cover and the door and the condition of the wipers and brakes, and find the fault and remove it in time. If the vehicle is turned off during wading, it should be quickly evacuated from the dangerous area before the water level has risen completely. Never wait for rescue in the car, otherwise the electric doors and windows will be locked automatically when the water level is too high, endangering personal safety.
China Weather.com warmly reminds all candidates and parents to go out early, no matter how urgent things are, they must bring rain gear and pay attention to travel safety. (Text/Jiang Yi Data Support/Zhang Juan)
