The Influence of Damrey Typhoon on 08. 03 Rainstorm Process in Rizhao of Shandong LU Guirong 1 2 WANG Wen 1 YU Huaizheng 2 ZHAO Yujie 2 FEI Yanqin 2 1. College of Atmospheric ScienceNanjing University of Information Science and TechnologyNanjing 210044China 2. Rizhao Meteorological Bureaus of Shandong ProvinceRizhao 276826China Abstract Based on the aerological sounding and surface data and FY - 2D satellite data from 2 to 3 August 2012 the influence of Damrey typhoon on rainstorm process occurred in Rizhao of Shandong Province on 3 August 2012 was analyzed from the circulation patternphysical quantities and satellite image. The results showed that the rainstorm was caused by the cyclonic vortex of Damrey typhoon risen up on its own motive power. The rainstorm area mainly located at the front right side of typhoon moving direction and near the high energy tongue. The centre of vapor fluxnegative value area of vapor flux divergence and strong rising area of vertical speed was corresponding with the strong rainfall area. The pattern of low level convergence and high level divergence over Rizhao was beneficial to the maintenance of rainfall. Furthermore asymmetric structure of Damrey typhoon was a important cause of the rainstorm appeared in RizhaoThe cloud system of strong rainfall located at the front right side of typhoon moving directionand the central of strong rainfall was overlapped with the low value center of TBB and OLR. Key words typhoon rainstorm causes analysis
