What are meteorological elements?

Various basic physical quantities and various weather phenomena representing the state of the atmosphere. It mainly includes basic physical quantities such as atmospheric temperature, air pressure, humidity, wind, sunshine and radiation, as well as weather phenomena such as clouds, rain, visibility, precipitation and thunderstorms, and broadly includes derived quantities such as atmospheric stability and vorticity.

In China, centigrade scale (℃) is used to express the atmospheric temperature, and meteorological ground temperature is referred to as air temperature for short, which refers to the atmospheric temperature in the louver at the height of1.5m. Besides, the temperatures of the representative layers of the surface, underground and atmosphere should be observed. Mercury barometer is usually used for barometric observation. Wind measurement is usually divided into instantaneous wind and average wind in a certain period (such as one minute, ten minutes, etc.). Humidity indicates the content of water vapor in the atmosphere. Except the observation of clouds, especially the shape of clouds is mainly observed by observers, other meteorological elements can be measured by instruments. Among these main meteorological elements, some represent the nature of the atmosphere, such as pressure, temperature and humidity; Some indicate the movement of air, such as wind direction and wind speed; Some are phenomena in the atmosphere, such as clouds, fog, rain, snow, lightning and so on. Their respective definitions are: temperature: a physical quantity indicating the degree of heat and cold in the atmosphere; Of course, the meteorological elements are far more than these, and the above are only the most important meteorological elements. Generally speaking, the more meteorological elements you choose, the more you can objectively express the various conditions of the atmosphere. Meteorological elements include temperature, air pressure, wind, clouds, precipitation, visibility and air humidity. Among these main meteorological elements, some represent the nature of the atmosphere, such as pressure, temperature and humidity; Some indicate the movement of air, such as wind direction and wind speed; Some are phenomena in the atmosphere, such as clouds, fog, rain, snow, lightning and so on.
