How does the meteorological station forecast the weather?

The first step is to collect Ji Guang, air pressure, temperature and other data on the ground or sea surface through the equipment of some professionals. The World Meteorological Organization will further coordinate these data and finally successfully formulate a standard.

Data from meteorological satellites are more important. It can successfully collect data from all over the world and help meteorologists learn more information. By observing and detecting clouds, we can know cloud top temperature and make predictions. Of course, ground data is more important. Specialized weather radar can obtain rainfall information, such as area and intensity.

2. Data assimilation.

Data assimilation is to combine the collected relevant data with the basic digital model, carry out some meteorological analysis and get the basic answer. The final result is the optimal solution, which can know not only the temperature and humidity, but also the pressure, wind speed and wind direction at a glance.

3. Data weather forecast.

Then the atmosphere is simulated by computer, mainly according to the data assimilation results. However, because the equation is relatively complex, only computers can make predictions.

4. Output processing.

After calculating the results, people can understand the meaning of the data through processing, in which errors should be eliminated and some basic adjustments should be made to the data results.

These tasks used to be done by meteorologists, but now it is much simpler, the weather forecast is more accurate than before, and meteorologists can finish the work more easily.

5. Final display.

The first four steps are behind the scenes, and they are all preparing for the fifth step. The fifth and most important step is to display the calculation results, let everyone know the future weather and make corresponding preparations. In the past, people were curious about the weather like the sun, the moon and the stars, which was also a kind of display.
