The total precipitation was 12 6 mm, and the rain was not heavy

The total precipitation is not a lot of rain, and it is a light rain. In meteorology, the intensity of precipitation is divided according to the amount of precipitation in a day (24 hours). According to the intensity of precipitation, it can be divided into:

Light rain, moderate rain, heavy rain, heavy rain, heavy rain, heavy rain, very heavy rain. If the rainfall is less than 10mm in 24 hours, it is light rain. 24-hour rainfall of 10 25mm, moderate rain.

24-hour rainfall 25-50mm, heavy rain. So the total precipitation is not large, just a light rain range.

Millimeters of rain are not very large, according to meteorologists, millimeters of rain are equal to grams of square meters of precipitation, which is relatively small and usually brings only some light rainfall.

In daily life, we usually use millimeters to indicate the amount of rainfall. In general, light rain is less than 10 mm, moderate rain is between 10 mm and 25 mm, heavy rain is between 25 mm and 50 mm, heavy rain is between 50 mm and 100 mm, heavy rain is between 100 mm and 200 mm, and extremely heavy rain is above 200 mm.

So, according to the data you provide, millimeters of rain are relatively small and usually only bring some light rain, which will not have much impact.

Precipitation. 2 mm, which belongs to light rain.

Precipitation refers to the depth at which liquid or solid (melted) water that falls from the sky to the ground over a certain period of time accumulates on a horizontal plane without evaporation, infiltration, or loss. In mm, one decimal place is taken in meteorological observations. 1 mm of precipitation refers to the amount of precipitation that reaches a depth of 1 mm on an acre of land (666.7 square meters).

In meteorology, the intensity of precipitation is distinguished by precipitation, which can be divided into: light rain, medium rain, heavy rain, and heavy rain.

Heavy rainstorms, extraordinarily large god code rainstorms.

1. Light rain. Light rain: 1 day (or 24 h) rainfall less than 10mm.

2. Moderate rain. Moderate rain: 1d (or 24h) rainfall of 10-25mm.

3. Heavy rain. Heavy rain: 1d (or 24h) rainfall 25 50mm.

4. Heavy rain. Heavy rain: 1 day (or 24 h) rainfall of 50 100mm.

5. Heavy rainstorm.

Heavy rainstorm: 1 day (or 24 h) rainfall of 100 250mm.

6. Heavy rainfall.

Heavy rainfall: 1d (or 24h) rainfall of more than 250mm.

Rainfall 1mm refers to the depth of water per unit area of 1 mm, rainfall refers to the rain that falls from the sky to the ground, without evaporation, infiltration, loss and accumulation of water layer depth on the water surface, generally in millimeters, it can intuitively indicate the amount of rainfall.

China Meteorological Administration.

Provisions: The rainfall within 24 hours is called the daily rainfall, where the daily rainfall is less than 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 extraordinarily heavy rainfall.

Rain is a natural sight that is the water on the earth that receives sunlight.

After irradiation, it becomes water vapor.

It was evaporated into the air.

When water vapour meets cold air at high altitude, it condenses into small water droplets. These small droplets are small, with a diameter of only millimeters and a maximum of millimeters. They are small and light, held up by the updrafts in the air.

It was these small droplets of water that gathered into clouds in the air. For these small droplets to fall to the ground as raindrops, they would have to increase in size by more than 1 million times.

1 mm of precipitation refers to the amount of precipitation on one acre (square meter) to reach a water depth of 1 mm.

Precipitation intensity is a measure of the magnitude and speed of rainfall. Precipitation is measured by the depth of rain that falls from the sky to the ground (the scale includes rain, snow, fog, etc.). There are generally two ways to represent the amount of precipitation:

One is measured by the depth of rainfall (snow) and the other is measured by the amount of rainfall (snow) per unit of time.

Generally speaking, light rain refers to rain with precipitation of no more than 10 mm in 24 hours, moderate rain is mm, heavy rain is mm, heavy rain is mm, heavy rain is mm, heavy rain is 100-250 mm, and extremely heavy rain is more than 250 mm.

Rainfall 12 mm is moderate rain: 1d (or 24h) rainfall 10 25mm.

Rainfall is measured with a rain gauge or rain gauge in mm. In the daily rainfall observation, it can be divided into 4 types: 24 segments (1 hour period), 3 hours (6 hours 1 stage) and 1 stage (24 hours stage).

There are two methods of daily rainfall statistics: 20 20 o'clock and 08 08 o'clock, and the daily rainfall published in China's TV and radio programs is 08 08 o'clock, which represents the rainfall of the previous day.

Essentials:

1) Rainfall duration and rainfall time: Rainfall duration refers to the duration of a rainfall, that is, the time experienced by a rainfall from beginning to end. Rainfall time refers to the length of time that corresponds to a certain amount of rainfall, during which the rainfall is not necessarily continuous.

The duration and duration of rainfall are measured in min and h.

2) Rainfall intensity: refers to the amount of rainfall per unit time, measured in mm min or mm h.

3) Rainfall area: refers to the horizontal area covered by a certain rainfall, measured in km2.

4) Rainstorm center: refers to the local area where the intensity of rainstorm is concentrated.

1.The depth of the water layer that falls from the sky to the ground, and the depth of the water layer that accumulates on the surface of the water without evaporation, infiltration, or loss, is called rainfall (in millimeters), which can visually indicate the amount of rainfall. At present, the commonly used instruments for measuring rainfall include rain measuring cylinders and measuring cups.

The diameter of the rain gauge is generally 20 cm.

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

20 mm of precipitation.

It's moderate rain. 20 mm of precipitation means that the depth of rainfall reaches 20 mm in 24 hours, and according to the classification of precipitation, it can be seen that 20 mm of precipitation type water belongs to the moderate rain level.

1. Light rain: the rainfall is less than 10 mm, the raindrops are clearly identifiable, 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.

2. Moderate rain: the rainfall is between 10-25 five millimeters, the sound of rustling rain can be heard, the rain falls like a line, the raindrops are not easy to cover and sell guess, and the water falls into the house hole and the hard ground slightly splashed, and the puddle is formed quickly.

3. Heavy rain: the rainfall is between 25-50 mm, when it rains heavily, the rain falls like a downpour and blurs into pieces, and the raindrops fall to the roof tiles and hard ground and splash up to several inches, the rain sound is like a drum, and the waterhole is formed very quickly.

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

Precipitation is uncontrollab.

It's centimeters. In the empty state of our daily life, if a millimeter of rain falls within an hour, it is a moderate to heavy rain, and there is a little water in the ground, and if it rains millimeters in a day, it can basically seep all into the ground.

Length unit conversion, the original unit is mm, the core target unit is centimeter, the base system is, and the calculation is equal to how many centimeters:

times is equal to centimeters. Zheng Sen.
