Weather is a general term for the atmospheric state (such as cold and warm, wind and rain, dryness and humidity, cloudy and sunny, etc.) and its changes in a certain area within a short period of time. Weather systems usually refer to atmospheric motion systems with typical characteristics such as high pressure, low pressure, high pressure ridges, and low pressure troughs that cause weather changes and distribution. Various weather systems have certain spatial and temporal scales, and systems of various scales are intertwined and interact with each other. The combination of many weather systems and clouds

constitutes a large-scale weather situation and constitutes the atmospheric circulation of the hemisphere and even the world.
