摘要：根据北大西洋个别气旋通过期间的特殊传感器微波成像仪 (SSM/I) 卫星数据得出的降雨案例研究，旨在增强对与锋面系统相关的降雨过程的了解。采用多卫星方法每天两次完整覆盖北大西洋。不同的 SSM/I 降水算法已针对单个气旋进行了测试，并与全球降水气候学项目 (GPCP) 数据集进行了比较。使用自愿观测船（VOS）数据集和高级甚高分辨率辐射计（AVHRR）图像提出了一种独立的降雨模式和强度验证方法。冬季频繁发生强烈气旋，冷锋在北大西洋上空向南传播。继上游之后，大云团经常嵌入背面区域的细胞结构冷空气中，从而产生强对流降雨事件，特别是在该地区...
Abstract Case studies of rainfall, derived from Special Sensor Microwave Imager (SSM/I) satellite data during the passage of individual cyclones over the North Atlantic, are presented to enhance the knowledge of rainfall processes associated with frontal systems. A multisatellite method is applied for complete coverage of the North Atlantic twice a day. Different SSM/I precipitation algorithms have been tested for individual cyclones and compared to the Global Precipitation Climatology Project (GPCP) datasets. An independent rainfall pattern and intensity validation method is presented using voluntary observing ship (VOS) datasets and Advanced Very High Resolution Radiometer (AVHRR) images. Intense cyclones occur frequently in the wintertime period, with cold fronts propagating far south over the North Atlantic. Following upstream, large cloud clusters are frequently embedded in the cellular structured cold air of the backside regions, which produce heavy convective rainfall events, especially in the regi...
