改进的精细分辨率雷达探测强对流效果评估.

A new-generation of weather radar (CINRAD/ SA Radar) at Zhuzilin, Shenzhen was partially upgraded in 2018. The highest resolution of detected data has been increased from 1 ° x 250 m to the current 0.5 ° x125 m, and the body scanning time has been shortened from 6 min to 4 min. In 2019, a radar at Xiasha, Hangzhou increased the maximum resolution of detected data from 1 ° x 250 m to the current 0.5 ° x 62.5 m, and shortened the body scanning time from 6 min to 4 min. By comparing and analyzing the detection effects of processed fine resolution radar data and original resolution radar data for different severe convection weather types, it is known that finer spatial resolution of the fine resolution radar data, especially with the improvement of dual polarization radar, had obvious advantages on observation and identification of small - and medium-scale strong convective clouds, and during some processes it could identify convection monomer and thunder cloud earlier, and had some improvement effect on quantitative precipitation estimation, indicating significant improvement on the application of radar in routine operation and scientific analysis compared with ordinary resolution radars.
