摘要(Abstract)：

本文利用FNL(Final Analysis)再分析资料、MODIS可见光云图和CloudSat卫星数据,对2012年1月10—13日发生于西北太平洋上的一个爆发性气旋进行了分析,并分析了1月12日02 UTC该爆发性气旋的云微物理属性的垂直结构。结果表明,该爆发性气旋中心附近的云为深厚宽广的深对流云,云系向上伸展到9km左右的高空。云中冰粒子有效半径大小随高度增加而减小,其大值集中在冰云下部。而冰粒子数浓度随高度增加而增加,其大值集中在冰云上部。云中冰水含量随高度变化不明显,其大值集中在云的中下部。冰粒子有效半径、冰粒子数浓度和冰水含量大值区在气旋中心南侧的高度比北侧更高,气温高值区和比湿大值区也集中于气旋中心南侧,这可能与冷暖空气的空间配置及气旋中心南侧有更显著的潜热释放有关。据此可以推测,云系在气旋中心南北侧有明显差异可能与云的不同发展机制有关。
