What is a weather system?
An atmospheric motion system in which meteorological elements such as temperature, pressure or wind have certain spatial structure characteristics. If it is.
Characterized by the distribution of air pressure in space, it consists of high pressure, low pressure, high pressure ridge and low pressure trough. Others are classified according to the distribution characteristics of wind, such as cyclone, anticyclone and shear line. Some are determined by the characteristics of temperature distribution, such as the front. There is another rule.
It is divided into some weather features, such as thunderstorms and tropical clouds. Usually, there is a certain configuration relationship between air pressure, wind, temperature and meteorological elements that constitute a weather system. The spatial range of various weather systems in the atmosphere is different, and the horizontal scale can range from several kilometers to 1-2000 kilometers. Its life history is also different, ranging from hours to days.
