ABSTRACT

The analysis and application of the raindrop spectrum data can effectively help us understand the physical nature of precipitation more effectively, and it also enables us to more clearly understand the evolution process of the natural precipitation process, starting with the instrument principle of the laser raindrop spectrometer and analyzing Raindrop spectrum, precipitation kinetic energy, combined with dual-polarization radar data and precipitation data from automatic weather stations, can be used to evaluate the difference between the precipitation model and the ZI relationship after the introduction of polarization parameters. This can be used as a basis to enhance the laser raindrop spectrometer. The measurement accuracy provides better support for climatology research. The laser raindrop spectrometer can automate the measurement of raindrop spectrum. It can give raindrop spectrum measurement curve in real time, statistically classify precipitation particles, and give instantaneous rainfall. The intensity and cumulative precipitation are very important for studying the development process of precipitation and guiding people to prevent extreme weather such as floods and floods in advance. In summary, studying the laser raindrop spectrum and improving its measurement accuracy has important research significance. Through analysis and research, it can be found that the comparison of the precipitation measured by the laser raindrop spectrometer at the same time and the raindrop at the automatic weather station can find that the maximum value of the raindrop spectrum measured by the laser raindrop spectrometer is greater than the automatic The maximum value of precipitation measured by the rain gauge in the weather station and the comparison of the time at which the peak points occur can be obtained. The peak value measured by the laser raindrop spectrometer is earlier than the peak value measured by the rain gauge, and then the two Comparing the data with the dual-polarization radar data, it can be found that the data of the laser raindrop spectrum is more similar to the data of the dual-polarization radar, and both data can be used to correct the precipitation error.

Key words: laser raindrop spectrometer, C-band dual-polarization radar, automatic weather station, data analysis and application
