Abstract:
This paper employs the data from atmospheric sounding comprehensive test site in CMA (China Meteorological Administration) from August to December in 2015, and carries on the contrast analysis about cloud base height, cloud top height and cloud vertical structure to the Kaband millimeter wave cloud radar and Lband sounding data. The analysis result indicates that the electromagnetic wave transmitted by the millimeter wave cloud radar can penetrate the thick clouds to detect cloud vertical structure, keeping a good consistency with the results of sounding. Further analysis of some large differences in individual cloud base and top height shows that the difference is correlated with the sounding balloon drifting caused regional deviation and the Lband sounding relative humidity detection error. The results finally show that the detection capability of Kaband millimeter wave cloud radar is strong, and the detecting precision is higher, thus the radar is an effective means of the groundbased cloud detection.
