Since the flood season in North China, the strongest rainfall will reach its peak, with wide influence range and strong intensity

The last round of strong convective weather has not gone far, and a new round of heavy rainfall has already played its role in the northern region, and this round of heavy rainfall process can not be underestimated.

The Central Meteorological Observatory predicted that from the night of 11 to 13, there was a heavy rainfall process in the eastern part of Northwest China, North China, Northeast China, Huanghuai River and other places, with heavy to heavy rain in some areas and heavy rain in local areas. From 20:00 on August 11 to 20:00 on August 12, heavy to heavy rain occurred in some areas of Western Inner Mongolia, Ningxia, southern Gansu, southwest Shaanxi, central and Western Sichuan Basin, central and Southern Hebei, Beijing, northern Tianjin, western Shandong, and Northern Henan. Severe convective weather such as short-term strong rainfall, thunderstorm, gale or hail occurred in the above areas. The Central Meteorological Observatory continued to issue storms at 18:00 on August 11 Yellow rain warning.

Zhang Tao, chief forecaster of the central meteorological station, analyzed at the ventilation meeting on the 11th that this round of rainfall has the characteristics of wide range, strong intensity and moving from west to East. This round of heavy rainfall started from Gansu, Ningxia and Shaanxi on the 10th, extended to Shanxi and Hebei, and arrived in Liaoning and other Northeast regions on the 13th. The local daily rainfall in Beijing Tianjin Hebei region will not be ruled out to be more than 200 mm. This process is the strongest precipitation since the flood season in Beijing, Tianjin, Hebei and Liaoning provinces.

Taking Beijing as an example, the main period of rainfall in Beijing is from noon to night on the 12th, and the rainfall gradually weakens and ends on the morning of 13th. It is estimated that the average rainfall of the whole city is 40-80mm, and the maximum hourly rainfall intensity can reach 80-100mm along the mountains in the West and North, with lightning and local short-term gale during the rainfall.

Three early warning! The meteorological risk of mountain torrents is high

Under the influence of heavy rainfall, the risk of geological disasters and mountain torrents is also greatly increased. At present, flood meteorological risk early warning, mountain torrent disaster meteorological warning and geological disaster meteorological risk early warning are issued simultaneously.

From the perspective of early warning area, Sichuan Basin and southwest of Beijing need to focus on the prevention of various meteorological disasters.

The central meteorological station has issued a flood weather risk warning for small and medium-sized rivers at 18:00 on August 11: affected by rainfall, it is estimated that from 20:00 on August 11 to 20:00 on August 12, the meteorological risk of small and medium-sized river floods in Western Hebei, southwest Beijing and Western Sichuan Basin is high (yellow warning), among which, the meteorological risk of small and medium-sized River flood in some areas of Sichuan Basin is very highuff08 Red Alert).

At the same time, the Ministry of water resources and China Meteorological Administration jointly issued the meteorological warning of red mountain torrents at 18:00 on August 11: it is estimated that from 20:00 on August 11 to 20:00 on August 12, the possibility of mountain torrents in some areas such as central and Northern Sichuan and southern Gansu is high (orange warning), and the possibility of mountain torrents in Central Sichuan is very high (red warning).

At 18:00 on August 11, the Ministry of natural resources and China Meteorological Administration jointly issued the meteorological risk warning of geological disasters: it is estimated that from 20:00 on August 11 to 20:00 on August 12, the meteorological risk of geological disasters in some areas, such as central and Northern Sichuan, southern Gansu, southwest Shaanxi, Southwest Beijing and central Hebei, is relatively high (yellow warning).

Beijing flood control headquarters announced on the 11th that there will be heavy rain in Beijing from the morning to the night of the 12th. It is suggested that all units implement flexible working system and work at home. Citizens are advised to reduce travel, park vehicles and pay attention to safety and avoid going to mountainous areas, scenic spots, rivers and dangerous areas. It is suggested that the construction site in the whole city should be stopped. At 20:00 on August 11, Beijing Municipal Commission of planning and natural resources and the Municipal Meteorological Bureau jointly issued a yellow warning on meteorological risk of geological disasters. In the next 48 hours, the risk of geological disasters such as debris flow, collapse and landslide will be high in Beijing mountainous areas.

Affected by heavy rainfall, the official microblog of Badaling Great Wall and Yuanmingyuan site park also announced that from 0:00 on the 12th to 24:00 on the 12th, Badaling Great Wall, Badaling Shuiguan Great Wall, Badaling ancient Great Wall and Yuanmingyuan Ruins Park and other scenic spots will be closed and all tourist reception activities will be suspended.

There will be another heavy rain in the north this weekend

Several successive strong convective weather let many netizens in the North feel puzzled: is this climate normal?

According to Zhang Tao, since this year, extreme weather such as heavy rainfall, drought and high temperature have occurred frequently. In fact, such weather will occur on a large scale in China every year. Affected by the location of the main rain belt, South China, South China and Northeast China will successively usher in heavy rainfall; and areas controlled by the subtropical high will also face long-term high temperature or drought, which is a long-standing climate phenomenon.

However, judging from the flood situation in the early stage of this year, it should be relatively extreme. Meteorological monitoring shows that there will be a precipitation process in northern China from the 15th to the 17th of this month. At present, it seems that the intensity is slightly weaker, but there are also large variables. In order to avoid the geological hazards and strong weather hazards in mountainous areas, we should try our best to avoid the geological hazards in the shallow mountains and rivers. Strong convective weather, such as short-term heavy rainfall and strong wind, has an impact on urban operation, transportation, agricultural production, etc. the public should try to reduce travel and do not stay under tall buildings, billboards, temporary structures or big trees. Extended reading for a new round of heavy rainfall in many places to start flood control level IV emergency response, Beijing, Tianjin and Hebei rainfall schedule released! There was heavy rain from noon to night in Beijing on the 12th. The strongest rainfall occurred in the flood season in Beijing, Tianjin and Hebei Province. It is expected that there will be heavy rain in the local area starting from the morning of the 12th_ NB16727
