Comparison of the Cloud Water Content Retrieved by Radar and from Numerical
The fully elastic three-dimensional convective storm model (IAP-CSM3D) established by the Institute of Atmospheric Physics (IAP), Chinese Academy of Science was used to simulate a strong convective storm that occurred in Hunan province on Apr.23th, 2004. The reflectivity observed by the Doppler weather radar was used to retrieve the water content, and established two display modes, which are CAPPI and VCS. Calculation field is defined as the square grid area with the radar station as center, with the horizontal side length of 150km, with the height of 30km, and with the distinguish ability of 1km*1km*1km. To retrieve the cases water content in comparison with the water content from the numerical modeling. The result as the follow is indicated: the constant value line distribution of the retrieved water content is parallel to the simulated output as a whole no matter in the development stage or in the strong stage of the storm, and the strength in the storm center as well as the height position is consistent well, that reflect the storm structure on the whole and the retrieve effect is rather perfect.
