How many millimeters is the rainstorm standard for the collapse of many buildings in Suizhou, Hubei?

The rainstorm in Zhengzhou just reassured people. As a result, there was another rainstorm in Suizhou, Hubei Province, which led to the collapse of many buildings. Let's see what it is!

Heavy rain in Suizhou, Hubei Province caused many buildings to collapse.

On August 12, many places in Hubei were hit by heavy rain.

Suizhou, Hubei Province is one of the hardest hit areas. The heavy rain caused Liulin Town to be flooded, and many towns and villages such as Hongshan, Changgang and He Dian were seriously affected.

Mr. Xiao, a citizen, said that his hometown Sanligang Town was seriously affected and the building next door had collapsed. There are many similar ones. The water depth is two or three meters in the morning, and the drinking water well can't be used. He has lived here for almost 30 years, and this is the first time he has seen such heavy rain.

It is reported that Sanligang town has been generally cut off from water and electricity, the road surface has been seriously washed away, cars can't get in, and materials can't be shipped out. The roadblock has been cleared.

Captain Li of Suizhou Blue Sky Rescue Team said that unlike the previous rescue in Zhengzhou, Suizhou is a hilly area and the water flow is relatively urgent. When I came, I found that the road surface was seriously damaged and the subgrade was washed away by water.

What is the standard of rainstorm?

There are three criteria for judging rainstorm, which generally refer to the precipitation with hourly rainfall greater than16mm, or continuous rainfall greater than 30mm within12h, or continuous rainfall greater than 50mm within 24 hours. According to China's meteorological regulations, rain with a precipitation of more than 50 mm in 24 hours is called "rainstorm". According to its precipitation intensity, it can be divided into three grades: "rainstorm", "heavy rainstorm" and "extremely heavy rainstorm". "Rainstorm" refers to the precipitation with a 24-hour precipitation of 50-99.9 mm; "rainstorm" refers to the precipitation below 100 ~ 200mm; "Extraordinary rainstorm" means that the precipitation exceeds 200mm.

Due to different regions and different topographical features, the storm and flood standards in each region are also different. Rainstorm is a kind of disastrous weather, which often causes floods and serious soil erosion, leading to major economic losses, such as engineering accidents, dike burst and crop flooding. Especially for some low-lying and relatively closed areas, heavy rain will cause greater disasters to agriculture.

Will the rainstorm thunder?

Lightning is a discharge phenomenon in thunderstorm clouds. The formation of thunderstorm clouds should meet certain conditions, that is, there should be enough water vapor in the air, the power to make wet air rise, and the air should be able to produce strong convection. Spring and summer are affected by the warm and humid airflow in the south, with humid air and strong solar radiation. The air near the ground is constantly heated up, and the upper cold air sinks, which is easy to form strong convection, so there are many thunderstorms and even hail.

When the air is extremely unstable, it is easy to have strong upward convection and form towering cumulonimbus clouds. Clouds are full of water vapor running up and down, which will generate static electricity. The upper end of the cloud will produce positive charge, the lower end of the cloud will produce negative charge, and the ground will be positively charged. Then, there is air as an insulator between the positive and negative charges. If the voltage difference between positive and negative charges is large enough to break through the air of the insulator, the air will instantly expand, explode, heat and glow.

When it thunders and rains heavily, close the doors and windows at home and check the electrical appliances. If you are in the wild, don't stand in the open field, don't stand under a tree, and don't take an umbrella. Pay attention to safety in everything

Will the rainstorm damage the car?

No, after the rain, the air humidity is high, and the car is humid at ordinary times, which is easy to breed bacteria and affect people's health. Therefore, after the heavy rain, the car must be inspected and properly disinfected.

It rained all night, will the car break down?

In-car maintenance can not only create a clean and comfortable interior environment, but more importantly, it can enable car owners and passengers to enjoy a safer and healthier experience in the car and avoid the harm of bacteria in the car.

In addition, car owners should always replace the air conditioning filter. Under normal circumstances, the service life of an original air conditioner filter is 20,000 to 30,000 kilometers. If you often drive on dirt roads or roads with poor air quality, you should shorten the replacement cycle in due course. After getting wet by rain, sludge will accumulate on the wheel cavity side and chassis, which is easy to hide moisture in the chassis, leading to rust of the car.

The wheel cavity of an automobile may even be loose and perforated, which may easily lead to safety accidents, especially braking. Because of too much water, the braking force of the car may decrease, which will slow down the braking response of the car, thus affecting the performance of the car and even causing safety accidents.
