What role do meteorological satellites and weather radar play in typhoon monitoring and forecasting?

Radiosondes are released, balloons are used to carry instruments that can measure air pressure, temperature, humidity, wind direction and wind speed at all levels at high altitude, and wireless telegrams are automatically sent out to detect various meteorological conditions at high altitude.

Use the plane to carry all necessary instruments to detect whether a typhoon occurs in the area where it may occur. After the typhoon, you can also cross the typhoon in all directions and at all heights to detect various phenomena in the typhoon on the spot.

According to all kinds of data obtained, forecasters of meteorological stations analyze typhoon trends, landing places and times, issue typhoon forecasts, typhoon emergency reports or emergency warnings in time, serve the public through television, radio and other media, and provide decision-making basis for governments at all levels. Issuing typhoon forecast or emergency report is an important measure to reduce typhoon disaster.

Satellites can predict atmospheric circulation, temperature, topography, typhoon location, intensity, seawater temperature, subtropical high and so on ~

If there is no satellite prediction, we can only leave it to chance. Although the forecast is sometimes inaccurate, it gives us time to prepare for future typhoons and minimizes the losses.

The experimental data and operational experience obtained provide meaningful data for the development and management of subsequent satellites. Fengyun-1A is China's first sun-synchronous orbit, which indicates that China has become one of the few countries in the world that can independently develop, launch and operate meteorological satellites.

FY- 1C runs in the sun synchronous polar orbit of 90 1 km. The design life of the satellite is 3 years. The main remote sensor of the satellite is a very high-resolution visible-infrared scanner. The number of channels is increased from five on Fengyun 1A B to 10, and the resolution is 1 100 meters. Remote sensing data obtained by satellites are mainly used for weather forecasting and environmental monitoring, such as vegetation, ice and snow cover, floods and forest fires. FY- 1C satellite was officially listed in the world polar-orbiting meteorological satellite sequence by the World Meteorological Organization because of its stable in-orbit operation and accurate data acquisition, and became the first satellite in China to be listed in the world meteorological operation.

Fengyun-1 meteorological satellite is the first polar-orbiting remote sensing satellite in China. Its main task is to obtain atmospheric, cloud, land and ocean data at home and abroad, and collect relevant data for weather forecast, climate forecast, natural disasters and global environmental monitoring.
