How to watch the weather situation map of CCTV

When CCTV broadcasts the weather forecast, it often plays satellite cloud pictures, accompanied by weather system maps and rainfall distribution maps, to explain the current weather situation, the changing process and development trend of the weather system, and the distribution of large-scale weather elements in the next 24 hours and 48 hours. At the same time, it also forecasts the weather conditions in major cities and provides accurate meteorological information for the general audience.

The so-called satellite cloud image means that meteorological satellites shoot images of the earth's atmosphere in space and then transmit them automatically, and then the ground satellite data receiving station displays images of a large range of cloud conditions through an image automatic transmission device. Clouds are a symbol of the weather. By analyzing cloud images and comparing the distribution and development trend of weather systems, we can understand the weather phenomena that will happen.

Tools and materials CCTV weather forecast video tape, TV set, video recorder.

Activity flow 1, reading satellite cloud pictures.

(1) Freeze the video on the satellite cloud image.

(2) Find out the moving direction of ocean (blue), land (green), cloud area (broken gray-white mass) and cloud cluster (red arrow) on the cloud image.

(4) Point out the moving direction of these cloud systems.

2. Understand the weather system.

(1) Consult relevant data to understand the contents of weather system (typhoon, high pressure, low pressure, cold front, warm front, quasi-static front, high pressure ridge, low pressure trough, trough line, shear line, etc.). ).

(2) Be familiar with the distribution of weather systems on weather maps.

(3) According to the distribution of weather systems, analyze the national weather situation (the combination of various weather systems is called weather situation).

3. Grasp the development trend of weather system.

(2) Pay attention to the analysis of the development trend of weather systems in weather forecast (such as the moving path of typhoons or the development trend of weather systems such as high and low pressure centers and rain areas).

(3) Analyze what kind of weather system will affect this area, that is, analyze the impact system.

(4) According to the local weather system that will be affected, analyze the weather situation that will appear.

(5) Compare the analysis of local weather trends in the weather forecast with my own analysis.

4, access to relevant information, familiar with the meteorological symbols and graphics in public meteorological services.

5. Understand the weather symbols appearing in the weather forecast of each city.

Explain and extend 1. The satellite images we saw on TV were processed by meteorologists on the computer. It is more in line with people's visual habits and easy to read.

2. We can record the satellite cloud pictures and analysis notes every day in the coming week with a video recorder, and then play them centrally, which is of great benefit to understanding the weather cloud pictures and mastering the weather situation analysis. Because we can compare the analysis of TV stations with the actual weather conditions.

3. It is not enough to predict the local weather trend only by reading TV satellite cloud pictures and weather system distribution, but also by comprehensively analyzing local meteorological data, so as to correctly predict the weather.
