Abstract:
In order to improve China New Generation Weather Radar (CINRAD) low level detection performance and accuracy of the wind storm top height, this paper studies and designs a volume coverage pattern (VCP) for CINRAD using SRTM geographic information data. It aims to improve CINRAD detection ability in lower layers by adding the number of elevation angles in lower and middle layers as well as negative elevation angles. We took Fuzhou and Longyan radar as examples to compute elevation angles for precipitation mode, and derived their new observation mode VCP12. Observation experiment results show that radar detection ability in the lower atmosphere can be improved after low or negative elevation angles are added.
