Many places in the north ushered in heavy rainfall, where is the focus of flood control in the north

These are the key points in areas such as hydropower stations, low-lying areas, areas with abundant water sources, river dams, etc., and drainage in a timely manner to prevent excessive rainfall.

Beijing, Liaoning, Tianjin and other places will be the focus of flood control in the north, especially in mountainous areas and places with dense rivers.

Many places in the north will usher in the heaviest rainfall since the flood, I think the focus should be on some low-lying areas, geological disaster points, and places prone to debris flows.

Many places in the north have ushered in heavy rains, and the flood has not been able to go down for a long time, so it is necessary to use the flood storage area to reduce the water level downstream, protect more than 10 million acres of farmland in Huaibei, and protect large cities along Huaibei.

Heavy rains in many places in the north ushered in. The recent heavy rainfall in the north is mainly concentrated in the central and eastern parts of Liaoning, the central part of Jilin, the southeastern part of Heilongjiang, the central and northern parts of Shaanxi, and most of Shanxi. Therefore, these areas are the ones we should focus on protecting.

The focus of flood control in the north is in Beijing, Tianjin, Xingtai and other places. Beijing has a large population and many modern buildings, which will reduce the amount of drainage, Tianjin is near the sea, and the Haihe River passes through the urban area to prevent the flooding of the Haihe River, Xingtai is a mountainous area, and heavy rain will cause mudslides.

Beijing, Tianjin and other cities need to be more warned, strong defenses, and waterlogging in the city. This trembling rainfall process has a wide range, the rain belt moves fast, and is dominated by convective rainfall, which will be the strongest rainfall process in North China, Huanghuai and other places since the flood this year.

Beijing, Tianjin, Jinan, Zhengzhou, Shenyang, Shanzao, Henan, Hebei and other places should do a good job of preventing hidden birds, and be vigilant against the sudden turn of drought and flood that may be caused by local heavy rainfall.

It should be Beijing, Anhui, Hefei, Hefeng, Beinan, Qingdao and other places that need to do a good job of rebellion, because this heavy rainfall can be very serious.

**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.

The heaviest rainfall since the flood in the north is coming, and the weather in some areas will change significantly, and there will be regional heavy rainstorms in the southern part of Shaanxi and the eastern part of the southwest region, as well as the central and eastern parts of North China, and there will be obvious changes, and the amount of precipitation will increase sharply, so it is necessary to strengthen precautions.

According to the relevant forecast information of the ** Meteorological Observatory, it can be seen that from the 26th to the 28th, there will be a yellow warning for heavy rain in some areas, and there will be strong convective weather in some areas. It will be found that from the 26th to the 27th, there will be heavy rainstorms in some areas, especially in the east and south of the Sichuan Basin, as well as in the central and southern parts of Liaoning, as well as Beijing, Tianjin, Shandong, Henan and other places, and when it rains, there will be short-term heavy precipitation and thunderstorms, and there may also be strong convective weather, resulting in hail.

In North China, Huanghuai and other places will also usher in the strongest rainfall, the process and scope of the rainfall is relatively wide, because the speed of the rain is relatively fast, the rainfall is dominated by the mobility of heavy rainfall, in the Huanghuai and other places in North China will appear the strongest rainfall This process is relatively long, and the 26th and 27th are the strongest rainfall periods. On the 27th, most of Jilin and the southeast of Inner Mongolia and the southern part of Henan will have heavy rain, and on the 28th, there will be moderate to heavy rain in western Guangxi, eastern Heilongjiang, and central Hunan, and there will be heavy rain or heavy rain in some areas.

Most of the hot areas in the north have begun to subside, but the sultry season in the south continues to be affected by cold air and precipitation in terms of temperature. There was a high temperature in the north, and although it decreased on the 26th, the number of high temperatures increased again. And there will be a wide range of high temperature phenomenon in the Huanghuai area, after the increase in humidity and stuffiness after education, it will stumble, so that there will be a particularly hot situation, this kind of hot and humid weather will affect people's mood, but also affect people's production and life.

In southern Shaanxi, central and eastern North China, Huanghuai, Jianghan, Northeast China and other regions, the temperature in these areas will become higher, and there will also be heavy rainstorms.

Qinghai, Gansu, Ningxia, Tianjin, Beijing, Shandong, Henan, Shaanxi and other places.

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.
