利用广西区气象台逐日上网的０８时中低层物理量中小尺度分析场格点资料、卫星云图，结合天气环流形势、水文资料，对梧州“九八”特大洪灾进行分析研究，探讨６月１６～２６日西江流域持续性暴雨及梧州致洪的成因，找出一些致洪特征，提出梧州抗洪防灾的一些措施。 Based on the mesoscale and meso-scale data of mid- and low-level physical quantities and the satellite imagery of the mid-low-level physical quantities at 08 hours of daily surfing on the Internet by the Guangxi Meteorological Observatory, combined with the weather circulation and hydrological data, an analysis was made on the “1998” extraordinary flood in Wuzhou. The causes of the persistent torrential rain in the Xijiang River Basin and the flood caused by Wuzhou identified some characteristics of flooding and put forward some measures for flood control and disaster prevention in Wuzhou.
