Analysis of a major storm over the Dongjiang reservoir basin associated with Typhoon Bilis
An unexpected major storm on July 14,2006,resulted in great loss to the Dongjiang reservoir basin in Zixing City,Hunan Province,China,during the dominance of Typhoon Bilis (2006).The rainfall characteristics and temporal evolution of this major storm were studied with rain gauge data and high-resolution radar reflectivity data to investigate the connections between typhoon,reservoir and convective storm.Our inves-tigations found that the intense convective storm,which was characterized by a banded structure,brought heavy rainfall concentrated in the Dongjiang reservoir basin while the center of Typhoon Bilis was nearly 450 km away from the basin.By applying geographical information system techniques,analyses of radar reflectivity demonstrated that the topography of the Dongjiang reservoir has big influence on the development of convective storm.Furthermore,intense convective cells with strong radar reflectivity (>50 dBZ) arose more frequently over the edges of the reservoir,especially over the southern mountain valley in the basin.More importantly,our investigations indicate that the occurrence of this convective storm is closely related to a strong atmospheric inversion by examining the Atmospheric Infrared Sounder data.
