What is the difference between climate and weather?

The earth's atmosphere is constantly moving and changing, so the weather phenomena people see are always ever-changing. Sometimes the sky is clear and the wind is calm and the sun is bright, and sometimes it is densely clouded and the wind is violent and the rain is violent, which is characterized by rapid changes. Weather refers to the comprehensive condition of a place's air temperature, air pressure, temperature and other meteorological elements in a short period of time, as well as the resulting atmospheric phenomena such as wind, clouds, and rain.

Climate refers to the combination of weather conditions that occur accidentally in a certain area for many years and special years. Climate and weather are closely related: weather is the basis of climate, and climate is a summary of weather. The climate characteristics of a place are reflected by the multi-year average values ​​of various meteorological elements (temperature, humidity, precipitation, wind, etc.) in the region and the extreme values ​​in special years. For example, the climate in Beijing: the average temperature in January is -4.7°C, the average temperature in July is 26.1°C, the lowest temperature record is -22.8°C (January 13, 1951), and the highest temperature record is 42.6°C (June 1942) 15th); the average annual precipitation is 636.8 mm, and the precipitation in summer (June-August) accounts for 74% of the annual precipitation. In summary, Beijing's climate characteristics are: cold and dry in winter, high and rainy in summer.
