Weather forecast icons and meanings
1. First, determine how large the area you want to forecast is. For example: Beijing city is within the scope and requires cooperative forecasting by sounding balloons and MICAPS weather system software. If it is a certain township in a certain province or a certain city, it only needs to be combined with the weather data from the ground weather station 4 times a day and drawn into a weather map to make a forecast.
2. Weather forecasting requires the use of data from weather stations around the world, and the use of MICAPS software and geographic information projection technology to accurately place the station's data and location on a fixed map. Afterwards, professional meteorologists analyze this map and draw isotherms, isopylum lines, isobars, etc. based on numerical data, and draw troughs or ridges based on wind power and direction icons. Finally, a geographical map with only data information is made into a regional map with various meteorological elements. This work requires strong professional knowledge and relatively rich experience. A skilled weather forecaster can complete a rough analysis of a continent within 30 minutes using MICAPS. A more detailed analysis requires the use of more detailed meteorological station data.
3. According to the analysis, professional meteorologists write a weather forecast draft, which is then recited by broadcasters and recorded by TV directors, and a weather forecast is completed.
my country’s weather forecast currently uses the MICAPS system. But for rain forecasts, generally refer to Japan’s forecast. Europe is more flexible, and each country may use certain forecasts from other countries when forecasting. For example, German rain forecasts are relatively accurate, and the Netherlands uses German analysis results when making rain forecasts.
It should also be noted that the weather forecast analysis of national meteorological bureaus (or central meteorological bureaus) in various countries is shared within meteorological departments around the world
