Cloud Vertical Profiles from CloudSat Data over the Eastern Tibetan Plateau during Summer

  • 摘要: 本文利用CloudSat卫星资料,对青藏高原东部2006~2010年6~8月云垂直结构的空间分布进行分析,结果表明:(1)夏季青藏高原东部云发展可达到平流层,且高原东部云在5km以下以水云存在,5~10km以液相和固相共存的混态存在,在垂直高度10km以上以冰云存在。由于CloudSat卫星资料云相的反演问题,可能会造成水云和混态云的发展上限偏低,冰云的发展下限抬升。(2)研究区整层水汽输送和云水平均路径空间分布存在一定的差异性,云水含量纬向分布表现为在26.5°~30.5°N附近存在一个明显的峰值区,经向分布表现为95°E以西云水含量低于以东。(3)研究区以单云层为主,尤其在青藏高原主体。单云层平均云层厚度4182 m,云顶高度、云厚限于水汽的输送,表现为由南向北波动下降。多层云发生频率在27°N以北明显减少,说明强烈的对流运动更容易激发多层云的产生。
