摘　　要：1987年5月24日云物理专业考查飞机对大兴安岭火区上空的云进行了水平观测。对此次观测结果的分析与研究表明:(1)来自空间状及空间技状区域的冰粒子(25—800μm)及降水粒子(200—6400μm)平均浓度较高;而来自枝状及枝星状区域的冰和降水粒子其平均浓度较低。(2)依据不同降水粒子形态所计算出的降雪强度以空间枝状为最大。Horizontal observations, were made of the clouds over tne area ot Daxinganling forestfires on May 24, 1987, using airborne PMS probes. The analysis shows that (1) the ice crystals(25-800 μm)a,nd precipitation paticles (200-6400μm) from space and the the regions for space-dendrites forming appear with their higher concentrations, comparing to those from the regions with dendrites and stells,(2)the sowfall with space-dendrites shows the highest indensity among the various precipitation particles.
