What's the meteorological manuscript?

Atmospheric pressure is short for atmospheric pressure. The pressure acting on any surface due to the weight of the atmosphere is expressed in Pascal (Pa). The change of air pressure is closely related to weather and seasonal changes, as well as temperature and altitude. The air pressure difference in the horizontal direction will cause airflow, thus forming wind.

The spatial distribution and temporal variation of air pressure are closely related to the air flow field and weather changes. So it is one of the main basis of weather analysis; In addition, air pressure can be used to determine the flying height of an aircraft in aviation; In the military, air pressure is also used to calculate the density of air for trajectory correction; Therefore, air pressure is one of the important factors that need to be measured in meteorology.

Generally speaking, meteorology refers to all atmospheric physical phenomena such as wind, clouds, rain, snow, frost, dew, rainbow, halo, lightning and thunder.
