Why is the unit of precipitation not expressed in milliliters, but used

This is determined by the definition of precipitation.

Precipitation refers to the depth at which liquid or solid (melted) water falls from the sky to the ground, without evaporation, infiltration, or loss, but accumulates on the horizontal plane, and precipitation of 1 mm refers to the amount of precipitation that falls on one acre of land (666 7 square meters) to a depth of 1 mm.

Extended information: According to the intensity of precipitation, it can be divided into: light rain, moderate rain, heavy rain, heavy rain, heavy rain, and extremely heavy rain.

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

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

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

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

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

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

The unit of precipitation is milliliters, which is right.

Precipitation (mainly refers to: rainfall, snowfall) is measured in millimeters or liters of square meters.

That is, it is assumed that there is a container with a bottom area of 1 square meter, and the depth is how many millimeters in 24 hours. Generally, it is measured in 24 hours, and sometimes there are special circumstances, such as heavy rainstorms, which are also calculated as short periods, such as 1 hour. 100 millimeters of precipitation is equal to 100 liters of square meters of precipitation.

Here are the reasons that affect the amount of precipitation::

1. Location factor.

In view of the influence of sea and land location on the water of the land, Chinese mainland is dry and rainless, and the coastal shore is humid and rainy.

2. Atmospheric factors.

The precipitation in the area controlled by the low pressure zone is relatively high, while the precipitation controlled by the high pressure is relatively low. In the monsoon circulation, the summer monsoon receives more precipitation than the winter monsoon.

3. Topographic factors.

In the terrain, the windward slope has relatively more precipitation, while the leeward slope has less precipitation, and the high rise and noisy terrain will prevent water vapor from entering.

4. Ocean current factors.

The warm current has the effect of warming and humidifying the coastal climate, and the cold current has the effect of cooling and dehumidifying the coastal climate.

5. Influence of vegetation and hydrological conditions.

Areas with high vegetation coverage, lakes, marshes, and reservoirs have high humidity in the air and relatively high precipitation.

6. Human activity factors.

There are more updrafts in the city, which is easy to form rain clouds and cause rain, and there is more dust in the city, and the more condensation there is, which leads to the urban wet island effect, and the greater the precipitation.

Precipitation is measured in millimeters, and precipitation is the depth at which liquid or solid (melted) water falls from the sky to the ground, without evaporation, infiltration, or loss, and accumulates in the horizontal plane. In mm, one decimal place is taken in meteorological observations.

Precipitation is a measure of how much precipitation falls in an area. Specifically, it refers to the depth at which liquid and solid (melted) precipitation falls from the sky to the ground, accumulating in the horizontal plane without evaporation, infiltration, and loss.

20mm of precipitation is equivalent to moderate rain in life.

In meteorology, there are often yearly, monthly, daily, 12-hour, 6-hour or even 1-hour precipitation. All the rain and snow that falls during the year melt into water, which is called annual precipitation. The average annual precipitation of a place over many years is called the average annual rainfall of that place.

The total amount of water vapour contained in the air column is also known as the precipitable amount. It corresponds to the amount of precipitation that can be formed by all the moisture in the air condensing into rain and snow falling. The amount of precipitation is about 1 to 2 times greater than the actual precipitation.

However, in strong precipitation systems, especially in thunderstorms, the actual precipitation often significantly exceeds the precipitable precipitation, due to the continuous convergence of air containing a large amount of water vapor into the precipitation system. The amount of precipitation is small in cold regions and large in the tropics. The average amount of precipitation available globally is about 25 mm.

The average for China is close to this.

1. The unit of rainfall is mm as the unit of measurement.

2. Precipitation.

precipitation) refers to the depth of liquid or solid (melted) water that falls from the sky and falls to the ground without evaporation, infiltration, or loss, but accumulates on a horizontal plane. In mm, one decimal place is taken in meteorological observations. The amount of precipitation in 1 mm is the amount of precipitation on one acre of land (666 7 square meters) to reach a depth of 1 mm.

3. Precipitation: Data that measures the amount of precipitation in an area. Specifically, it refers to the depth at which liquid and solid (after melting) precipitation falls from the sky to the ground, accumulating in the horizontal plane without evaporation, infiltration, and loss.

Precipitation is measured in millimeters (mm).

1. Definition of precipitation unit:

Precipitation refers to the total amount of water that falls over an area over a certain period of time. It is an important concept in meteorology and is used to describe the change and exchange of moisture in the atmosphere. The unit of precipitation can vary depending on the needs and measurement methods.

2. Millimeter (mm):

The millimeter is one of the most common and widely used units of precipitation. It indicates the thickness of moisture falling on each square meter of ground, i.e. 1 millimeter of thickness if precipitation is evenly distributed on each square meter of ground.

3. Metric units:

In addition to millimeters, there are a number of other metric units used internationally to describe the amount of precipitation. The most common of these is the cubic meter per square meter (mm) or known as the kilogram per square meter (kg m), which indicates the mass of precipitation per unit area. Such units are more used in the field of scientific research and engineering technology.

4. British chaos collapse unit:

In English-speaking countries, precipitation is often expressed in imperial units. The most common of these is the inch (inch), which indicates the thickness of rainfall. 1 inch is equivalent to a millimeter.

In addition, there are units such as feet and yards, which indicate that the depth of rain is 1 foot or 1 yard, respectively.

5. Influence of precipitation measurement methods:

The choice of the unit of precipitation is closely related to the measurement method. Different precipitation measurement devices and techniques use different units. For example, weather stations often use rain gauges to measure precipitation, which is measured in millimeters.

Technologies such as radar echoes and satellite remote sensing are described in units such as cubic meters per square meter or kilogram per square meter.

6. Conversion and conversion:

In practical applications, it may be necessary to convert and swap between different single-pitch round positions. For example, to convert precipitation from imperial units (such as inches) to metric units (such as millimeters), you can use a conversion relationship: 1 inch = millimeter.

In addition, it is possible to make use of special unit conversion tools or formulas for calculations.

7. The importance of precipitation:

Precipitation is an important parameter in climate and environmental research, and is of great significance for agriculture, water resource management, weather forecasting, etc. By accurately measuring and monitoring precipitation, issues such as climate change, the hydrological cycle, and water allocation can be better understood, providing a scientific basis for decision-making.

Summary:

The unit of precipitation is millimeters (mm), which indicates the thickness of moisture that falls on each square meter of ground. In addition to millimeters, there are units such as cubic meters per square meter (m m), kilograms per square meter (kg m), inches (inch), etc., which are used to describe the amount of precipitation. Unit selection is closely related to the measurement method, and different units are used for different measuring devices and techniques.

In practice, unit conversion and conversion may be required. Accurate measurement of precipitation is important for climate research and decision-making.

Precipitation refers to the total amount of rain that falls over a certain period of time, usually using millimeters (mm) as a unit. To disturb the branch is about the precipitation unit of the slow desensitization in more detail:

Definition of precipitation: Precipitation refers to the statistical data of the amount of rainfall in a certain area in the past.

Millimeters as a unit: A millimeter is a unit of length, but in meteorology, it is also used to indicate the amount of precipitation. Because when the rate of precipitation collected inside the rain gauge is amplified to per square millimeter, it can determine the amount of precipitation by simple measurements.

Other units: In addition to millimeters, precipitation can also be expressed in other units, such as centimeters, inches, and ounces, among others.

Method of measuring precipitation: Precipitation can be measured using a rain gauge. A rain gauge is a device specifically designed to measure precipitation, which accurately measures precipitation by directing rainwater into a funnel-like container and measuring the level inside the container.

In summary, the unit of precipitation is millimeters, which is the most commonly used representation in meteorology. If you want to measure precipitation accurately, you can use a dedicated rain gauge to do so. Hope, thank you!
