What is a weather system?
Weather system is an atmospheric motion system with typical characteristics, which is divided into high pressure, low pressure, high pressure ridge and low pressure trough according to the spatial distribution of meteorological elements. Sometimes it refers to the wind distribution system, such as cyclone circulation, anticyclone circulation, shear line and so on. Sometimes it also refers to the system of temperature distribution, such as high temperature zone, low temperature zone, front zone and so on. Sometimes it refers to the distribution system of weather phenomena, such as thunderstorms and tropical clouds. There is often a certain configuration relationship between this element system and another element system.
The relationship between pressure system and wind field is good: low pressure and cyclone circulation are matched, sometimes called low pressure and sometimes called cyclone; The configuration of high pressure and anticyclone is sometimes called high pressure and sometimes anticyclone. Air pressure system and temperature system often have a certain configuration relationship. For example, the configuration of low pressure and low temperature zone is called cold low pressure or cold vortex; The configuration of low pressure and high temperature zone is called thermal low pressure. The atmospheric pressure system can also have a certain configuration relationship with weather phenomena, such as thunderstorm and high pressure configuration, which is called thunderstorm high pressure. The weather system can be analyzed by various weather maps and satellite cloud images.
