What will be the impact of the heaviest rainfall in North China on local production and life?

North China ushered in the heaviest rainfall, which will inevitably affect people's travel, easily induce serious flood disasters, and affect the production and life of residents

Recently, North China has ushered in the heaviest rainfall into the flood, Beijing after a round of heavy rain, issued six warnings in a row, and ushered in the second wave of heavy rain in the past two days. Torrential rain is easy to induce flash floods, floods, mudslides, landslides and other natural disasters are prone to occur, which is bound to affect local agricultural production, and heavy rain weather will also affect people's travel and bring inconvenience to people's lives.

First of all, heavy rain is prone to flood disasters, and the drainage system in some areas is not perfect, and flood disasters will inundate farmers' crops, which will have a serious impact on the production situation of the year. Some areas prone to flash floods are often flooded by mudslides and flash floods, causing losses to people's property and even people. Local production is also bound to be affected by heavy rains, and in some areas the harvest depends entirely on crops, and the floods caused by heavy rains will inevitably cause losses.

In addition, it is not suitable to travel in heavy rainy weather, so in order to avoid accidents, local residents are advised not to go out easily. Some office workers should work flexibly as much as possible, work from home and reduce going out, so as to prevent unnecessary injuries caused by heavy rains.

If a flood disaster occurs, the relevant departments in various localities must make a good plan to deal with it, rescue the people affected by the disaster in a timely manner, and try their best to go to the high ground to wait for rescue, so as to prevent the situation of being washed away. Relevant departments should also make preparations to prevent the occurrence of flood disasters, and if there are affected areas, they should carry out timely resettlement. After the flood disaster, it is necessary to investigate the electricity and other aspects of the village and urban area to prevent the occurrence of electric shock accidents, disinfect the drinking water of residents, and distribute epidemic prevention drugs in time to avoid the occurrence of infectious diseases after the flood disaster, and reduce travel first in safety!

Heavy rainstorms in northern China will bring certain benefits to the drought situation in agriculture, but if they are too large, they may cause landslides and other disastersSome experts said that the rainfall in Inner Mongolia, Shandong and Northeast China is less than in previous years, some areas have been drought, and some places have reached the level of severe drought, and the heavy rain is very beneficial to the drought in these areas, but the heavy rain is menacing, we should pay attention to preventing disasters such as flash floods and mudslides, and there will be heavy rain in Beijing and Hebei, so we try to avoid going out.

Heavy rainfall will alleviate crops in some arid areas of northern China, but it will also bring flooding in some areas. The weather network predicts that from the 21st to the 24th, many places will usher in heavy rainstorms, especially in Beijing, Tianjin and Hebei. Hebei and Inner Mongolia will have heavy rain weather, this rainstorm is the first heavy rainfall in North China this year, according to the analysis of the meteorological observatory, this heavy rain is Inner Mongolia to the east to bring the high-altitude low vortex, it is expected that the rainfall in the next few days will be greater, we should pay attention to flood control measures.

The strongest in North China will bring relief to crops in arid areas such as Shandong and Hebei, but it may also cause mudslides and urban waterlogging due to heavy rainfallThe center of this rainfall is the Beijing-Tianjin-Hebei region, the western and northern areas of Beijing have appeared in the world of heavy rain, some areas have also rained hail, the reason for the heavy rainfall is the eastward shift of Inner Mongolia to bring the high-altitude low-lying whirlpool, when these phenomena are formed at low latitudes, it is what we commonly call typhoons, and rain and snow weather will be produced at high latitudes.

It can cause river floods and landslides. In the next ten days, the area located in the middle and lower reaches of the Yangtze River will also face the situation of water level ** caused by excessive rainThe main rainfall will generally be heavy from July 1 to 6, and North China and Northeast China will follow, and after the 20th, the rainfall in the lower reaches of the Yangtze River in the south will be strengthened again, and the relevant departments should pay attention to flood prevention and early warning.

It causes great inconvenience to residents, affects the efficiency of local industrial production, and slows down the development of the city.

These heavy rains can cause flooding, and then there is some damage to crops, and then some shops on the street can't open because of the flooding.

Rainfall will affect travel, many office workers and businesses need to travel, if the amount of ** decreased, it will lead to a decrease in consumption, resulting in a downturn in the local economy.

The heaviest rainfall since the flood season in the north hits, which areas will have a significant rainfall process?

The Songhua River basin has the highest probability of impact, after the Songhua River flows out of the Changbai Mountain, runs through the Songnen Plain, and then enters the Sanjiang Plain to the northeast, the whole process is basically controlled by the continuous Changbai Mountain, Xiaoxing'an Mountains, Lao Ye Ling, Jilin Hadaling, etc., and the tributaries originating from these mountain ranges all flow into the Songhua River.

Together with the largest tributary, the Nenjiang River, it joins the Songhua River in the Songnen Plain area after collecting water from the Great Xing'an Mountains. and the second largest tributary, the Mudanjiang River, which joins the Songhua River in the Sanjiang Plain after collecting water from the Mudanling and Weihuling. Coincidentally, in the coming week, the maximum rainfall in the north will be concentrated in the Songhua River basin, so the entire northern region, the Songhua River basin is most likely to be affected by rainfall and produce floods.

In addition, like the Yellow River Basin, it is also possible to cause local floods, especially in the river section of Shanxi, the upper reaches of the Yellow River itself have formed two floods this year, and is currently in the stage of flood drainage and sediment transport, and the Fen River, a tributary of the Yellow River in Shanxi, also belongs to the main rainfall zone of the flood season, and the short-term heavy rainfall may cause local flooding in the Fenhe River Plain, and the Fen River into the Yellow Mouth may produce backflow phenomenon.

Of course, the main flood season in the north will also promote a large area to benefit and alleviate the drought for several days, such as Henan, Shanxi, Shaanxi, Hebei, the drought in these four provinces is relatively serious, especially in Henan and Hebei, the two main grain producing areas, the size of rainfall has a very large impact on grain production.

Moreover, the groundwater level in these areas has continued to fall in recent years, and most of the surface reservoirs and rivers are also drying up, and the large-scale rainfall can also play a certain role in alleviating the situation, but it will not return to the highest level in history, after all, the current groundwater level in North China is low, in addition to the lack of rainfall, the greater reason is the expansion of the demand for groundwater such as population growth, arable land expansion, and industrial development.

The amount of precipitation and the scope of influence of the rain belt affecting China will be expanded, and there will be moderate to heavy rain in Inner Mongolia, Northeast China, North China, most of the Huanghuai region, Jianghan region, southwest China and other places, among which, some areas in central and southern Liaoning, northeast Hebei, most of Shandong, northeast Sichuan Basin, northeast Chongqing and other places have heavy rain or heavy rain of magnitude of 100 160 mm.

There are all Shenyang areas, as well as Qinhuangdao, Chongqing, Zhumadian, Jilin, these areas will have significant rainfall processes, especially in Shenyang.

According to the weather forecast, there are heavy to heavy rains in southeastern Shaanxi, northwest Hubei, Henan, Shandong, Beijing, Tianjin, eastern Hebei, and central and southern Liaoning, and heavy rains in some areas such as Shandong and Henan, and relevant citizens should also be prepared accordingly.

**The Meteorological Observatory announced a blue warning for heavy rain on June 25: There were heavy rains or torrential rains in parts of southeastern Gansu, southeastern Shaanxi, Sichuan intermountain basin, central and southern Henan, central and western Shandong, southeastern Hebei, southeastern Beijing, southeastern Liaoning, and eastern Jilin, among which, there was heavy rain (100 120mm) in parts of southeastern Shaanxi and northern Sichuan intermountain basin. The above local areas are accompanied by short-term heavy rainfall (30 60mm rainfall in large hours, and can exceed 80mm locally), and there are heavy precipitation such as thunderstorms and strong winds locally.

This time, the rainfall process is very wide-ranging and fast-moving, and it will be the strongest rainfall in North China and Huanghuai this year. In particular, cities such as Beijing, Jinan, Tianjin and Shenyang need to take good measures for urban flood control. In addition, Henan, Shandong, Hebei and other regions should always be vigilant to prevent natural disasters caused by local heavy rainfall.

The rain in eastern Qinghai and Gansu is relatively strong, and there will even be heavy rain or heavy rain locally, and on the 26th, the main center of rainfall will gradually shift to the east. At the same time, with the generation of low-level low vortices and surface cyclones, coupled with abundant water vapor, heavy rainfall will be particularly obvious in the North China Plain and other areas. Heavy to heavy rain will also occur in southern Shaanxi, Shandong and Henan, especially in the southern part of Henan and the western part of Shandong, where heavy rainfall is likely to occur.

The general public should also prepare for heavy rainfall in advance. People should pay attention to the weather forecast in time, arrange their own schedules, try not to go out in heavy rainfall weather, and prepare sufficient food and other supplies in advance. Be careful when going out, bring umbrellas, raincoats, etc.

If the rain is too heavy and has caused a disaster, for example, if the house where the people live is relatively low, after the rain has entered the house, it is necessary to learn the corresponding evacuation measures, such as cutting off the power supply first, protecting their communication equipment, so as to contact the rescuers in time.

According to the weather forecast of the ** Meteorological Observatory, the northern part of our country is about to enter the flood season and usher in the heaviest rainfall. The rain will affect Henan, Shaanxi, Inner Mongolia and Northeast China.

Shandong Province is the epicenter of heavy rainfall. Precipitation in Jinan City, Shandong Province, and the eastern part of Hebei Province is the heaviest since the flood season, reaching about 100 mm to 250 mm. After spreading outward from this center, the western part of Shandong, the southern part of Hebei, and the northeastern part of Henan will also have different degrees of heavy rainfall, with precipitation of about 100 mm, of which Zhengzhou City, located in Henan Province, is also the center of heavy rainfall, and the largest amount of precipitation has reached about 250 mm, like Jinan City in Shandong Province.

Parts of Xi'an in Shaanxi Province and parts of eastern Chengdu will experience heavy rainfall. The heavy rainfall at the junction of Shaanxi and Sichuan provinces is about 250 mm. The amount of precipitation in an area of about a few tens of kilometers has reached 100 mm, and in areas centered on Chengdu and about 120 kilometers to the southwest, heavy rainfall can also occur.

Hebei, Ningxia, Gansu and many other provinces have about 10 mm to 25 mm of precipitation. Inner Mongolia has slight precipitation, mainly concentrated in the northeast, central and southwest regions of Inner Mongolia, Gansu precipitation is mainly concentrated in the central and western regions of Gansu Province, as well as the southern part of Yunnan Province, most of the areas in Sichuan Province are about 25 mm of precipitation. In addition to this, the southern region south of Guangzhou and the southeastern region of Guangdong Province will also experience 10 25 mm of precipitation.

In the three northeastern provinces, the central part of Heilongjiang Province and the southern part of Liaoning Province, there will be 25 mm of precipitation. In general, except for some areas such as Shandong, Shaanxi and Henan provinces, there is not much precipitation in other areas.

The rainfall is distributed in Henan, Hebei, Shaanxi and other places, the rain is rapid, gathering less into more, gathering in the river, down the river, will cause certain danger to Shanghai, Hubei and other cities along the Yellow River, the Yangtze River.

The heaviest rainfall since the flood in the north will affect the southeast of Northwest China, the eastern part of North China, the northeast region, Huanghuai, Jianghuai, Jianghan, the western part of Jiangnan, the western part of South China and the eastern part of Southwest China.

It has affected more than a dozen provinces, including the eastern and southern parts of the Sichuan Basin, the western and northern parts of Chongqing, the southeastern part of Shaanxi, the northwestern part of Hubei, Henan, Shandong, Beijing, Tianjin, the eastern part of Hebei, and the central and southern parts of Liaoning.

After experiencing extremely hot weather, many places in the north will usher in a heavy rainfall pattern, and more than 10 provinces in the north will experience heavy rain and extremely heavy rain, and there will be short-term thunderstorms against strong convective weather in some areas. The heavy rainfall will occur in Hebei, Shandong, Liaoning, Qinghai, Ningxia, Gansu, Inner Mongolia, Jilin, Shaanxi and Henan. Relevant departments must do a good job of defense to avoid causing losses.

Causes of heavy rainfall. The heavy rainfall was caused by a combination of subtropical highs, cold vortices and other climates. In summer, the simple subtropical high will cause the air flow to sink and the temperature will increase rapidly, and there will be drought and little rain at this time.

However, after the strong cold air moves south from the north, it forms a cold vortex with the surface cyclone, which is a counterclockwise rotating vortex and belongs to the low-pressure system. High and low pressure systems interact to create extreme rainfall. This is the reason for the heavy rainfall in the north.

Areas of heavy rainfall. The process of this rain will start from the northwest to the northeast. First of all, the southeast of the northwest region will be the first to start the rainfall process, and the eastern part of Qinghai, Ningxia and Gansu will have a heavy rainfall process.

It then began to move eastward, and then began to affect the North China Plain, at this time Hebei, Henan, Shaanxi, Beijing-Tianjin and Shandong will be affected by the process of heavy rainfall. It then continued to move northeastwards and began to affect the eastern coastal cities of Shandong, northern Hebei, southeastern Inner Mongolia and northeast China. Eventually, it will affect the entire Tohoku region.

Defense against heavy rainfall. When a rainstorm hits, be sure to do a good job of defense. First of all, the public must pay attention to local climate change and rainfall warnings.

People in high-risk areas try not to go out and wade in the water. If you must go out, you must go in a group, and if you encounter water on the road, you must take a detour. Drivers need to pay attention to driving safety.

If water enters the home, be sure to cut off the power supply. Farmers must strengthen the drainage of farmland to avoid damage to crops. People at risk of mudslides and landslides need to evacuate as soon as possible.
