【摘要】 通过对2000年8月加勒比海地区飓风Debby活动期间,连续2个时次中使用下投式探空资料同化分析后,利用英国气象局全球数值预报系统的数值预报分析场和背景场的对比分析,阐明了由于下投式探空资料的引入,较好地描述了实际大气的情况,为数值预报提供了较为接近实际的初始场,从而提高了数值预报的精度。其中以湿度场和风场的贡献为最大。更多还原

【Abstract】 Some case studies were done in this paper in order to improve the understanding about the impact of Dropsonde data on the NWP initial fields during Harricane Debby in Carribean Sea in 2000.The results showed Dropsonde data was very important to the NWP initial fields,especially humidity and wind fields.The initial fields can get more real statues of the atmosphere if Dropsonde data was used,and the forecast accuracy can be improved.更多还原
