The meaning of the weather

Weather means changing atmospheric conditions.

Weather refers to the ever-changing atmospheric state, which is not only the atmospheric state in a certain time and space, but also the continuous change of atmospheric state in a certain time interval. So it can be understood as a general term for weather phenomena and weather processes.

Weather phenomenon refers to various natural phenomena in the atmosphere, that is, the comprehensive expression of the spatial distribution of various meteorological elements in the atmosphere (such as temperature, pressure, humidity, wind, clouds, fog, rain, snow, frost, lightning, hail, acid rain, etc.). ) in an instant. Weather process is the process of weather phenomena changing with time in a certain area.

Weather refers to the specific state of the near-surface atmosphere in a short time. Weather phenomenon refers to various natural phenomena in the atmosphere, that is, the comprehensive expression of the spatial distribution of various meteorological elements in the atmosphere (such as temperature, pressure, humidity, wind, clouds, fog, rain, snow, frost, lightning, hail, etc.). ) in an instant. Weather is the change process of weather phenomena with time in a certain area.

Weather forecast:

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

The disastrous weather forecast plays an important role in protecting people's lives and property and promoting economic development. There are some errors in weather forecast because of the chaos of atmospheric process and the fact that science has not fully understood the atmospheric process.

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