How is the weather forecast monitored?

Modern weather forecasting systems are mainly divided into ground meteorological observation stations, ground meteorological radar systems, upper atmospheric meteorological observation, meteorological satellites and data analysis centers.

The ground weather station is mainly responsible for collecting meteorological data such as air pressure, temperature, humidity, wind direction, wind speed, precipitation, snow depth, sunshine time, cloud cover and air quality. On the one hand, these data are used to summarize the atmospheric activity information collected by other means for real-time weather forecast, on the other hand, they form a database as valuable information for long-term research on climate change.

The ground weather radar system emits electromagnetic waves with centimeter wavelength to the clouds in the airspace through radar facilities established in various places, and observes the formation of condensation nuclei, ice crystals, raindrops or snowflakes in the clouds within hundreds of kilometers. The data obtained by radar and the measurement results of ground observation stations are summarized and analyzed to realize the forecast of rain and snow weather.

Extended data:

The contents of the weather forecast include:

1, rain or shine in a region or city in the future.

2. The highest and lowest temperatures in a region or city in the future.

3. The future wind direction and force of a region or city.

4. Special disastrous weather in a region or city in the future.

As far as China is concerned, meteorological stations can accurately predict the location and intensity of natural disasters such as cold waves, typhoons and rainstorms, and can directly serve industrial and agricultural production and people's lives.
