摘要: 利用1998年华南暴雨科学实验期间香港风廓线雷达的高时空分辨率资料考察了中尺度数值模式MM5对6月8日到9日香港特大暴雨个例的风场模拟结果。研究表明MM5模式输出的风廓线和风廓线雷达的观测结果有很好的相似性,进一步确认了利用模式输出研究中尺度对流系统结构和机理的合理性。

Abstract: Comparisons were made between the characteristics of the wind profile observed by the wind profiler and the wind profile simulated by mesoscale numerical model(MM5)from 8th June 1998 to 9th June 1998 at Hong Kong. The results showed that the wind profile simulated by MM5 is similar to that observed by the wind profiler. This confirmed the rationality of researching the structure and mechanism of the mesoscale convective system using MM5.

Key words: numerical model, wind profiler, mesoscale convection system
