The important tool of weather forecast is weather map. Weather maps are mainly divided into ground and high altitude. The weather map is densely covered with various weather symbols, which are filled in after being translated according to meteorological codes all over the country.

Each symbol represents a particular weather.

The symbols representing clouds are Cirrus, cirrocumulus, cirrostratus, Altocumulus, nimbostratus, Cumulonimbus and so on.

Symbols representing weather phenomena include: thunderstorm, tornado, fog, continuous heavy rain, light snow and light showers.

In addition, there are symbols indicating the change of wind direction, wind speed, cloud cover and air pressure.

All these symbols are filled in their respective geographical positions in a unified format. In this way, meteorological elements such as wind, temperature, humidity, air pressure, clouds, cloudy, sunny, rain and snow observed at the same time in a wide area can be filled in a weather map. So as to form weather maps representing different times. With these weather charts, forecasters can further analyze and process them, and express the analysis results with lines and symbols of different colors.

The analysis content of the ground weather map includes: drawing the regional scope of important weather phenomena (such as precipitation, gale, blizzard, etc.). ), draw the positions of cold front, warm front and quasi-static front, draw the isobar of the whole picture, and mark the center and intensity of low pressure and high pressure. Through this analysis, we can clearly see the atmospheric pressure at that time: where is the high pressure, where is the low pressure, and where is the confrontation zone between cold and warm air.

The meteorological element filled in the high-altitude weather map is the height of each point on the same isobar surface, so the contour lines separated by a certain value are analyzed and drawn. After the contour line is drawn, we can see the pressure situation at that time: where is the trough of low pressure and where is the ridge of high pressure. Then draw an isotherm and mark the cold and warm center. From the configuration of heating and cooling center, low pressure trough and high pressure ridge, forecasters can make a general judgment on the future air pressure situation.

With the development of meteorological science and technology, some meteorological stations have used advanced detection tools and forecasting methods such as meteorological radar, meteorological satellites and electronic computers to improve the level of meteorological forecasting and achieved remarkable results. It is reported that since 1966, typhoons in tropical oceans around the world have almost never escaped the "eyes" of meteorological satellites. Satellite cloud images play an important role in monitoring and early detection of severe storms and severe disastrous weather.
