How big is the biggest rainstorm you ve ever experienced?

When I was very young, it was about one day in elementary school that it had a heavy rain, and it was so heavy that it broke a tree in front of my house, and its rain even caused floods around us.

I have the impression that one night after self-study, but the rain is very heavy, you have to go home, and then you can only walk outside the school gate with an umbrella, the rain is very large, and then the wind is also very large, and then the umbrella is bent by the rainstorm, the whole person is soaked, the umbrella is useless, and then the trees planted in the green belt on the side of the road are blown down by the wind and rain, and it was really frightening at that time.

The biggest storm I've ever had was when it flooded the little saplings in front of my door, and it was really big, and the water got into the house and soaked our beds in the water, and it was really scared to death.

During the summer vacation of my sophomore year of high school, there was a heavy rainstorm, which was really heavy, and all the families near the embankment were flooded, and the water level of the Yangtze River had reached the highest water level, and there was a danger of bursting the embankment at any time.

In my memory, I encountered one of the biggest rainstorms, saying that once when I was working in Hefei for summer vacation, the rainstorm was very heavy, and now it is very fierce, and a lot of rainwater has accumulated on the road outside, all up to our knees.

One time I had a very heavy rainstorm, and then because of a problem with the drainage system on our side, and then the whole water was knee-high, and it was so scary, like a river, it couldn't get out at all.

It was when I was very young, and the torrential rain that rained for several days caused the levee next to our village to burst and the flood water overflowed into the village, and the houses were so deep that people ran to the higher places to pitch their tents.

It's the feeling of pouring rain, because once when I was at home, I saw that the rain was really heavy, and it hurt very badly, and that time I didn't have any fish, so I was very unlucky.

We are close to the Yangtze River here, and when we were young, there were big floods almost every year, and during the summer vacation every year, there were people moving on the streets, and then the water came. One time the water was after school, the water rose to the knees, touched the water and went home, and lost sandals on the way.

It's like someone is pouring cold water on you with a basin all the time on top of your head, and I really don't want to experience it a second time, and I think that the crops will be bathed in the water all the time.

Almost, as high as a fast neck.

Light rain: rainfall within 10 mm, heavy rain: rainfall between 25 and 50 mm, heavy rain: rainfall between 50 and 100 mm, rainfall more than 200 mm is called extremely heavy rain.

When we listen to or watch the weather forecast radio, we often hear terms such as "light rain", "moderate rain", "moderate to heavy rain", etc., which is the level of rainfall. Rainfall refers to the depth at which rainwater that falls on the ground without evaporation, infiltration, or loss.

Our country stipulates that the unit of depth is millimeters. The level of rainfall is divided into light, moderate, heavy, heavy rain, heavy rain, heavy rain, and extremely heavy rain according to the amount of rainfall in 24 hours.

Light rain: the rainfall is less than 10 mm, the raindrops are clear and discerning, and the rain does not splash when it falls on the roof tiles and hard ground, and the rain sound is gentle and dripping; It usually takes two minutes for the slabs and roof tiles to be fully wetted, and puddles form slowly. Moderate rain:

The rainfall is between 10 and 25 mm, and the rustling of rain can be heard, the rain falls like a line, the raindrops are not easy to distinguish, and the fall falls on the house holes and hard ground slightly splashed, and the puddles form quickly. Heavy rain: The rainfall is between 25 and 50 mm, and when it rains heavily, the rain falls like a downpour and blurs into patches, and the raindrops fall on the roof tiles and hard ground and splash up to several inches, the sound of rain is like a drum, and the puddle forms very quickly.

Heavy rainfall: Rainfall is between 50 and 100 mm, and the road is waterlogged. Heavy rainfall between 100 mm and 200 mm of rainfall is called; Rainfall of more than 200 mm is called extremely heavy rainfall, and the low-lying areas are flooded.

Showers: refers to showers of precipitation, the raindrops are larger, the rain falls and stops, the intensity changes sharply, the sky is dark when it rains, sometimes it is suddenly cheerful, revealing a sunny day, and sometimes accompanied by thunder.

The China Meteorological Administration stipulates that the rainfall within 24 hours is called the daily rainfall, and all daily rainfall below 10 mm is called light rain, millimeters are moderate rain, millimeters are heavy rain, heavy rain is millimeters, heavy rainfall is millimeters, and more than millimeters are called extremely heavy rainfall.

Due to the vast territory of our country, the precipitation in the east, west, and north and south regions varies greatly. In a small number of areas, according to the specific conditions of the province, local standards for heavy rain have been formulated for local use. For example, in the rainy province of Guangdong Province, the daily rainfall of more than 80 mm is called heavy rainfall; In the Yan'an area of Shaanxi Province, where there is little rainfall, the daily rainfall of more than 30 mm is called heavy rainfall; Xinjiang has a dry climate and less precipitation, so the Xinjiang Meteorological Bureau has specially named rainy days with a daily rainfall of more than or equal to 10 mm as "heavy precipitation".

The amount of rainfall within 24 hours is called daily rainfall, where the daily rainfall is less than millimeters is called light rain, millimeters are moderate rain, millimeters are heavy rain, heavy rain is millimeters, heavy rainfall is millimeters, and more than millimeters are called extremely heavy rainfall.

Moderate rain: less than 10 mm of precipitation in a 24-hour period, or less than a millimeter of precipitation in an hour.

Heavy rain: Precipitation in a 24-hour period is less than a millimeter, or precipitation in an hour is less than a millimeter.

Heavy rain: Precipitation in a 24-hour period is less than a millimeter, or precipitation in an hour is more than a millimeter.

Heavy rain: Precipitation of less than millimeters in 24 hours, reaching or exceeding 200 millimeters.

Moderate rain: refers to the amount of rain in millimeters in 24 hours;

Moderate to heavy rain: refers to the amount of rain falling in millimeters in 24 hours;

Heavy rain: refers to the amount of rain falling in millimeters in 24 hours;

Heavy to heavy rain: refers to the amount of rain in millimeters within 24 hours;

Heavy rain: refers to the amount of rainfall in millimeters in 24 hours;

Heavy to heavy rain: refers to the amount of rain in millimeters in 24 hours;

Heavy rainstorm: refers to the amount of rain falling in millimeters in 24 hours;

Heavy to heavy rain: refers to the amount of rain in millimeters in 24 hours;

Extremely heavy rain: refers to the amount of rain that falls more than millimeters in a 24-hour period.

Moderate rainfall in 24 hours was 10 mm of rainfall, heavy rain of 25 mm, heavy rain of more than 50 mm, heavy rain of more than 100 mm.

Moderate rain: Rainfall in 24 hoursless than millimeters between, or the amount of rain that falls in an hourless than millimeters between

Heavy rain: The amount of rain that falls in a 24-hour periodLess than millimetersbetween, or the amount of rain that falls in an hourless than millimeters between

Heavy rain: Rainfall in 24 hoursLess than millimetersbetween, or the amount of rain that falls in an hourMore than millimeters.

Heavy rain: Rainfall in 24 hoursless than millimeters between, reach orMore than millimeters.

The formation of heavy rainfall

The process of rainstorm formation is quite complex, generally from the macroscopic physical conditions, the main physical conditions for the production of rainstorm are sufficient water vapor, strong and persistent upward movement of air current, and instability of atmospheric structure. Large, medium and small weather systems at various scales and a favorable combination of underlying surfaces, especially topography, can produce large rainstorms. The weather systems that cause widespread heavy rainfall in China mainly include fronts, cyclones, shear lines, low vortices, troughs, typhoons, easterly waves, and intertropical convergence zones.

In addition, localized thermal thundershowers in arid and semi-arid areas can also cause short-lasting, small-scale heavy rainstorms. Heavy rains often fall from cumulonimbus clouds. The condition for the formation of cumulonimbus clouds is that the atmosphere must contain sufficient water vapor, and there is a strong upward movement, which transports the water vapor rapidly upward, and the water droplets in the cloud are affected by the upward movement and continue to increase, until the updraft can no longer support it, and then it will fall sharply to the ground.

It's going to rain a little bit this afternoon, it's raining hard, don't stop raining, it's going to fall until 10 o'clock a week, I see how you're doing:

Heavy rain is not the biggest rain. The heaviest rain is the extremely heavy rain, and there is a clear distinction between heavy rains in our country's meteorology, and the rain with a 24-hour precipitation of 50 mm or more is called "heavy rain". According to the intensity of precipitation, it is divided into three levels, that is, the precipitation in 24 hours is 50 mm, which is called "heavy rain", and less than 100 200 mm is "heavy rain"; More than 200 mm is called "heavy rain".

Heavy rain: Heavy rain refers to rain with high precipitation intensity, often formed in cumulonimbus clouds. According to China's meteorological regulations, heavy rainfall with more than 50 mm of precipitation in 24 hours is called "heavy rain".

According to the intensity of precipitation, it is divided into three levels, that is, the 24-hour precipitation is called "heavy rain" in millimeters, and the "heavy rain" between millimeters is called "extremely heavy rain". However, due to the different precipitation and topographic characteristics in different places, the standards of heavy rain and flooding are also different in different places. In business practice, heavy rainfall can be divided into the following according to the size of the occurrence and impact range

Local rainstorms, regional rainstorms, large-scale rainstorms, and extra-large rainstorms. Local rainstorms last only a few hours or dozens of hours, and generally affect tens to thousands of square kilometers, causing relatively minor damage.

Heavy rain is not the biggest rain. The heaviest rain is the extremely heavy rain, and there is a clear distinction between heavy rains in our country's meteorology, and the rain with a 24-hour precipitation of 50 mm or more is called "heavy rain". According to the intensity of precipitation, it is divided into three levels, that is, the precipitation in 24 hours is 50 mm, which is called "heavy rain", and less than 100 200 mm is "heavy rain"; More than 200 mm is called "slow year heavy rain".

Heavy rain is not the biggest rain. The heaviest rain is the extremely heavy rain, and there is a clear distinction between heavy rains in our country's meteorology, and the rain with a 24-hour precipitation of 50 mm or more is called "heavy rain". According to the intensity of precipitation, it is divided into three grades, that is, the amount of precipitation in 24 hours is 50 mm, which is called "heavy rain", and less than 100 or 200 mm is "heavy rain"; More than 200 mm is called "extraordinarily large old thing rainstorm".

The ferocious and sudden rainstorm has brought a lot of trouble in Wuhan, for example, the footage taken by local netizens shows that some low-lying areas have been completely occupied by floods, some areas directly "look at the sea", and the time period of the rainstorm coincides with the morning rush hour, and road traffic has been significantly affected.

The heavy rain in the city of Wuhan was the most intense. The storm destroyed a particularly large number of buildings in Wuhan. And there is no way for everyone to go out at all.

The heavy rain in Wuhan is the most violent, because the geographical environment of Wuhan is actually more than that around many Haihe rivers, so this terrain is very prone to heavy rainfall.

Of course, it's Chongqing, because of the mountainous characteristics of Chongqing, now it's either heavy rain or hail, and I've never seen such a situation.

Mountainous areas, because the terrain in the mountains is relatively rugged, and the rainfall phenomenon is particularly severe, causing more serious flooding.

1. Heavy rainstorm.

2. According to the precipitation standard stipulated by the National Meteorological Department, the precipitation tolerance can be divided into six types: light rain, moderate rain, heavy rain, heavy rain, heavy rain, heavy rain and extremely heavy rain.

3. According to China's meteorological regulations, heavy rainfall with a precipitation of more than 50 mm in 24 hours is called "heavy rain", and less than 100 250 mm is "heavy rain"; Temperatures above 250 mm are called "heavy rainfall".

4. Heavy rainfall is a kind of disastrous weather, which often causes floods and serious soil erosion, resulting in major economic losses such as project wrecks, embankment failures and crop flooding. Especially for some low-lying and closed areas, the rainwater cannot be discharged quickly, resulting in water accumulation in farmland and oversaturation of soil moisture, which will cause more geological disasters.

Different departments have different criteria for the classification of rainfall levels.

Heavy rain generally refers to the rain with great precipitation intensity, and China's meteorological department stipulates:

Rainfall of 16 mm or more in 1 hour;

Rainfall of 50 mm or more in a 24-hour period; Heavy rain has the characteristics of "concentration" and "intensity", and when it appears, the rain is pouring down, causing water accumulation in the depression in a short time, the runoff increases sharply, and the river water rises sharply, which is a serious disastrous weather.

According to Chinese meteorology, rain with 50 mm or more of precipitation in 24 hours is called "heavy rain".

According to the intensity of precipitation, it is divided into three levels, that is, the 24-hour precipitation is 50 mm, which is called "heavy rain"; Below 100 250 mm is considered a "heavy rain"; Temperatures above 250 mm are called "heavy rainfall".

Due to the different precipitation and topographic characteristics in different places, the standards of heavy rain and flooding are also different in different places.

Heavy rainfall is a disastrous weather that often causes flooding and severe soil erosion, resulting in major economic losses such as engineering failures, embankment failures and crop flooding. Especially for some low-lying and closed areas, rainwater cannot be quickly discharged, resulting in water accumulation in farmland and oversaturation of soil moisture, which will cause more disasters.

The world's largest rainstorm occurred on the island of Reunion in the southern Indian Ocean, with 1870 mm of precipitation in 24 hours. The heaviest rainfall in China occurred in Xinliao, Taiwan Province, with 1,672 mm of precipitation in 24 hours, all caused by tropical cyclone activity.

China is one of the countries with a lot of heavy rainfall, and almost all provinces (cities, districts) have seen it. Mainly concentrated in the summer half of the year. The geographical distribution of rainstorm days is obviously more in the south and less in the north. More along the coast and less inland; It is characterized by more windward slopes and fewer leeward slopes.

Heavy rain days in Taiwan's mountainous areas reach more than 16 days a year, and in some areas of the Dongxing, Yangjiang, Shanwei and Jianghuai basins along the coast of South China it is more than 10 days, while the northwest region averages less than 1 day a year.
