Weather forecast, also known as meteorological forecast (measurement), 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). ).
Today's weather forecast is mainly based on the collection of a large number of data (temperature, humidity, wind direction and speed, air pressure, etc.). ), and then use the understanding of atmospheric processes (meteorology) to determine future air changes. Because of the chaos of the atmospheric process and the fact that science has not fully understood the atmospheric process today, there will always be some errors in the weather forecast.
History of weather forecast development;
Numerical value is the language of science. Weather forecast is inseparable from the quantitative observation of atmospheric motion by instruments. We can set the invention and application of meteorological instruments as the start time of early weather forecast.
/kloc-in the 5th century, the west invented the pressure plate anemometer, which can quantitatively measure the velocity (energy) of atmospheric motion for the first time. 17-18th century, scientists have successively invented various instruments for quantitatively measuring weather phenomena, marking the beginning of a new development period for the detection means of meteorological scientific research.
