| 摘要: |
| 本文根据17个登陆热带气旋的GMS云图、雷达回波照片、常规气象资料和116个气象台站每小时的自记雨量,分析了登陆热带气旋暴雨的时、空尺度以及暴雨落区,揭示了热带气旋暴雨的中小尺度特征和暴雨强度变化中的中尺度振荡,概括出热带气旋环流内部不同尺度系统的两种相互作用。最后还就一实例作了较详细的分析。 |

| Abstract: |
| On the basis of GMS images, radar echo pictures, conventional data and 116 hourly rain gauge records, the temporal and spatial scales and areas of heavy rain are analysed for 17 landing tropocal cyclones. The meso-and-fine scale characteristics of the heavy rain and its mesoscale osillations in intensity variation are revealed, and two interactions among the circulation systems of different scales inside the cyclones are presented. Finally, the case of typhoon Peggy in 1986 is studied in detail. |
