What is the weather forecast?

Weather forecast refers to the service of forecasting the future weather through the observation, analysis and prediction of meteorological elements.

Weather forecast is carried out by observing and analyzing meteorological elements. Meteorological elements include temperature, humidity, air pressure, wind direction, wind speed and precipitation.

The meteorological station will use various meteorological instruments to measure these meteorological elements. For example, temperature can be measured by thermometer, humidity can be measured by hygrometer, air pressure can be measured by barometer, wind direction and speed can be measured by anemometer, and precipitation can be measured by rain gauge.

These observation data will be transmitted to the meteorological center, which will analyze and process these data and then generate the weather forecast. Weather forecast can be carried out according to different time scales such as hours, days, weeks and months. Weather forecast is one of the important applications of modern meteorology and one of the indispensable services in people's daily life.
