Icons and meanings of weather forecast

1。 First, determine the area you want to predict. For example, for Beijing, it is necessary to cooperate with MICAPS weather system software for forecasting. If it is a township in a province or city, it is only necessary to match the meteorological data of the ground weather station four times a day and draw a weather map to predict it.

2。 Weather forecast needs to use the data of weather stations all over the world, and use MICAPS software and geographic information projection technology to accurately place the data and location of the stations on a fixed map. After that, professional meteorologists analyzed this map and drew isotherms, isohyets and isobars. Draw the wind direction map according to the numerical data, and draw the groove line or ridge line according to the wind direction map. Finally, a geographical map with only data is made into a regional map with various meteorological elements. This work requires strong professional knowledge and rich experience. A skilled meteorologist can complete a rough analysis of a continent in 30 minutes with MICAPS. More detailed analysis should use more detailed weather station data.

3。 According to analysis, a weather forecast is written by a professional meteorologist, then recited by the announcer and recorded by the TV director.

MICAPS system is currently used for weather forecast in China. But rainfall forecast generally refers to Japan's forecast. Europe is more flexible, and each country may adopt some specific forecasts of other countries when forecasting. For example, the rainfall forecast in Germany is relatively accurate, and the rainfall forecast in the Netherlands uses the analysis results of Germany.

It should also be noted that the weather forecast analysis of national weather bureaus (or central weather bureau) is enjoyed by global meteorological departments.
