摘要:
利用隆德气象站一次典型降水天气过程下HMB-KPS型与HT101型云雷达探测资料,结合同期常规地面、高空观测资料以及固原站天气雷达资料,对两种型号的云雷达在六盘山区的探测能力进行了对比分析。结果表明:(1)在降水前后的非降水背景下,HMB-KPS型在近地面100m内有一地物杂波,比同时次的HT101型云雷达探测到的云系更为深厚,回波强度值高10dBZ左右,信噪比高5~10dBZ左右,径向速度值高0.5m·s-1左右,谱宽值低0.5m·s-1左右,且云接地起止时间较HT101型云雷达早1h。(2)在降水背景下,HMB-KPS型比HT101型云雷达反演的回波强度较大值高4km左右,回波强度值高20dBZ左右,信噪比高10~20dBZ左右,径向速度高1m·s-1,谱宽值低0.5m·s-1左右。相关结果可为两部云雷达在人工影响天气业务中的应用提供技术参考。
Abstract:
This paper compares and analyses the detection capabilities of two types of cloud radar in the Liupanshan region using HMB-KPS and HT101 cloud radar data under a typical precipitation weather process at the Longde meteorological station, combined with conventional ground and high altitude observations and weather radar data from the Guyuan station during the same period. Results show that:(1) in the non-precipitation background before and after precipitation, the HMB-KPS has a ground clutter within 100m near the ground, which is deeper than HT101 cloud radar at the same time. The echo intensity is about 10dBZ higher, the signal-to-noise ratio is about 5~10dBZ higher, and the radial velocity is about 0.5m·s-1 higher. The spectral width is about 0.5m·s-1 lower, and the start and end time of cloud grounding is 1h earlier than HT101 cloud radar; (2)in the background of precipitation, the HMB-KPS has a higher echo intensity value of about 4km, a higher echo intensity value of about 20dBZ, a higher signal-to-noise ratio of about 10~20dBZ, a higher radial velocity of about 1m·s-1 and a lower spectral width value of about 0.5m·s-1 than the HT101 type cloud radar inversion. The results can provide a technical reference for the application of cloud radars in weather modification operations.
