Six elements of meteorology

These six meteorological elements are: temperature, humidity, air pressure, wind direction, wind speed and precipitation.

1, temperature:

Temperature refers to the degree of thermal movement of air molecules, usually expressed in degrees Celsius or degrees Fahrenheit. Weather stations use thermometers to measure temperature, such as mercury thermometers and electronic thermometers. The change of temperature has an important influence on people's daily life, such as clothing and living environment.

2. Humidity:

Humidity refers to the content of water vapor in the air, usually expressed by relative humidity. The change of humidity has an impact on human health, plant growth and textile quality. Weather stations use hygrometers to measure humidity, such as wet and dry bulb hygrometers and electronic hygrometers.

3. Air pressure:

Air pressure refers to the air pressure per unit area, usually expressed in kilopascals. The change of air pressure plays an important role in meteorology, weather forecast, aviation and other fields. Weather stations use barometers to measure air pressure, such as mercury barometer and barometer.

4. Wind direction:

Wind direction refers to the direction in which the wind blows, usually expressed in eight directions. The change of wind direction plays an important role in meteorology, climate research, aviation and other fields. The weather station measures the wind direction by using the commonly used wind vane.

5. Wind speed:

Wind speed refers to the distance the wind travels in unit time, usually expressed in meters per second. The change of wind speed plays an important role in meteorology, weather forecast, aviation and other fields. Weather stations use anemometers to measure wind speed, such as hot-wire anemometers and wind-pole anemometers.

6. Precipitation:

Precipitation refers to the precipitation per unit time, which refers to the liquid or solid water falling from the sky to the ground, including rain, Mao Mao rain, snow, sleet, graupel, ice particles and hail, usually expressed in millimeters.

Precipitation changes play an important role in agricultural production, water resources management, flood control and disaster reduction. Weather stations use rain gauges to measure rainfall, such as Tong Yuan rain gauge and tipping bucket rain gauge.
