摘要
对1950～2000年间登陆和影响广东省的台风造成的灾害进行分析,选取有完整记录的42例台风的台风强度、最大风速、最大日雨量作为主要气象因子,采用SAS系统建立了灾情评估模型,计算出历次台风的主要灾情数据,并且将评估值与实测值拟合。拟合的结果表明,可以通过气象数据,定量地大致估算台风的灾情。
Based on the data from Disaster Reduction in Guangdong, the typhoon disasters that occurred from 1950 to 2000 within the area of Guangdong Province were statistically analysed. By the method of SAS, an evaluation model was set up, of which 42 integrated records were picked up that include the basic meteorological factors--wind′s intensity, the maximum velocity of the wind and the maximum daily rainfall. The main data of the disasters were calculated and the evaluated values were compared with observed ones. The result indicates that the model can be devoted to the quantitative analysis of typhoon disasters.
