摘要研究了雪带聚集体的雪颗粒类型、边缘度和大小。根据实测数据，阐明了控制降水强度的微物理过程。结果表明：1)由团聚体组成的雪颗粒可分为三种类型：非粒状和轻粒状雪晶；有镶边或重镶边的雪晶，在镶边之前具有可辨的雪晶；和大量定时或霰状的雪颗粒。2)当降水强度(R)非常强（> ~ 5 mm h−1）时，非边缘或轻边缘雪晶约占构成团聚体的雪粒子总数的30%。3)无论降水强度如何，积雪颗粒大小分布无明显差异。4)虽然rbbb50 mm h−1时的云深大于r5 mm h−1时的云深。5)霰状粒子……
Abstract Types, degree of riming and size of snow particles comprising aggregates from snow bands were investigated. From the data obtained, the microphysical processes which control the precipitation intensity were elucidated. The results are summarized as follows: 1) Snow particles comprising aggregates were classified into three types: nonrimed or lightly rimed snow crystals; rimed or heavily rimed snow crystals having discernible snow crystals prior to riming; and heavily timed or graupel-like snow particles. 2) Nonrimed or lightly rimed snow crystals occupied about 30% of the total number of snow particles comprising an aggregate when precipitation intensity (R) was very intense (>5 mm h−1). 3) Regardless of the intensity of precipitation, there were no apparent differences in size distribution of snow particles. 4) Although the cloud depth was larger when R > 5 mm h−1 than when R 5 mm h−1. 5) Graupel-like particles...
