The meaning of weather

Weather means the constantly changing state of the atmosphere.

Weather refers to the atmospheric state that is constantly changing. It is not only the atmospheric state within a certain time and space, but also the continuous change of the atmospheric state within a certain time interval. Therefore, it can be understood as a collective name for weather phenomena and weather processes.

Weather phenomena refer to various natural phenomena that occur in the atmosphere, that is, various meteorological elements in the atmosphere (such as temperature, air pressure, humidity, wind, clouds, fog, rain, snow, Comprehensive performance of spatial distribution of frost, thunder, hail, acid rain, etc.). Weather process is the process of changes of weather phenomena in a certain area over time.

Weather refers to the specific state of the atmosphere close to the surface of a certain place in a short period of time. Weather phenomena refer to various natural phenomena that occur in the atmosphere, that is, various meteorological elements in the atmosphere at a certain instant (such as temperature, air pressure, humidity, wind, clouds, fog, rain, snow, frost, thunder, hail). etc.) comprehensive performance of spatial distribution. Weather is the process of changes in weather phenomena in a certain area over time.

Weather forecast:

Weather forecast refers to the use of modern science and technology to predict the state of the earth's atmosphere at a certain location in the future. Since prehistoric times, humans have begun to predict the weather to arrange their work and life accordingly (such as agricultural production, military operations, etc.).

Disastrous weather forecasts play an important role in protecting people's lives and property and promoting economic development. Due to the chaos of atmospheric processes and the lack of a thorough understanding of them by science today, weather forecasts are subject to certain errors.

Weather forecasting is based on meteorological observation data, applying the principles and methods of meteorology, dynamic meteorology, and statistics to make qualitative or quantitative predictions of the weather conditions in a certain area or location for a certain period of time in the future. It is an important goal of atmospheric science research. It is of great significance to people's lives.
