Visit the local weather station and talk about what measuring tools are available and what are their uses?

The weather station tells us what measuring tools are available, including cloud observation, micro-pulse lidar (MPL), visibility observation 1 and laser cloud altimeter: the time between laser emission and reception is measured by irradiating the clouds with laser beams, so as to calculate the distance of reflection points in the clouds, and the cloud amount is determined by integrating the time.

2. Micropulse Lidar (MPL): It can measure the temporal and spatial distribution monitoring of cloud bottom and multi-layer clouds, the temporal and spatial distribution monitoring of boundary layer, the vertical distribution and temporal and spatial evolution of aerosol.

3. Forward scattering visibility meter: the transmitter and receiver receive forward scattered light from the atmosphere at two places with a certain angle and a certain distance. The scattering coefficient is obtained by measuring the intensity of scattered light, and then the extinction coefficient is estimated.

4. Transmission visibility meter, which calculates visibility by measuring the average extinction coefficient of horizontal air column between transmitter and receiver.

CINRADCC weather radar is a new generation of C-band fully coherent Doppler weather radar used by China Meteorological Bureau for domestic meteorological service networking detection. The radar can monitor large-scale heavy precipitation targets such as tropical cyclones and heavy rains within 400 kilometers, and effectively monitor and identify small-scale strong weather phenomena such as tornadoes, hail clouds and hail over 200 kilometers. The measurement range of radial wind speed reaches about 36 meters per second.

The role of meteorological observation Meteorological observation is the basis of forecasting service, and the modernization of observation business is an important part of meteorological modernization. With the development of meteorological technology and business, meteorological observation is becoming more and more automatic, and the content of observation is becoming more and more abundant.
