What is the weather? What is the weather?

1, differences in noun interpretation:

Atmospheric physical states and phenomena are called meteorology. Such as wind, lightning, thunder, frost, snow, etc. Meteorological phenomena are observable weather events that can be explained by meteorology. These events are determined by the variable factors in the earth's atmosphere, which are temperature, air pressure, water vapor, gradient and the interaction among them.

Weather:

The general name of atmospheric conditions (such as dry and wet, sunny and cloudy, wind and rain, cold and warm, etc.). ) and its changes in a short time in a certain area. Records of meteorological elements such as temperature, air pressure, humidity, wind direction and wind speed are the basic basis for expressing weather. Weather and climate are two concepts that are both related and different, and climate is a comprehensive expression of long-term weather conditions in a certain area.

2, popular science explanation:

When you turn on the radio, TV or newspaper, you will hear or see the weather forecast information. Terms such as "weather", "weather" and "climate" are often encountered in this information; When you want to go somewhere on business, always ask others about the climate and weather there. But what are the exact meanings of "meteorology", "weather" and "climate" and what are their differences? Anyway, someone may confuse it with the weather! In fact, the meanings of the three are quite different, but they are closely related.

"Meteorology", in layman's terms, refers to all atmospheric physical phenomena such as wind, clouds, rain, snow, frost, dew, rainbow, halo, lightning, thunder and so on. "Weather" refers to the comprehensive situation that affects the instantaneous meteorological characteristics of human activities. For example, we can say: "Today the weather is fine, sunny and sunny, with clear skies in Wan Li;" Yesterday, the weather was terrible, there was a storm, and so on; "Climate" refers to the multi-year characteristics of meteorological conditions of the whole earth or a certain region in a year or a period. For example, Kunming has four seasons like spring; In most areas of the Yangtze River basin,

It is mild in spring and autumn, hot in midsummer and cold in winter, so we call it temperate climate with four distinct seasons. The rainy season in Beijing is from the end of July to the beginning of August every year.

Therefore, the connotations of "meteorology", "weather" and "climate" are obviously different and cannot be confused.
