盛夏东北地区北部两次MCC活动云场和环境场特征分析

Analysis of the character of two MCC's cloud and environment fields in the north of northeast region in summer.

利用MICAPS2.0平台对东北北部连续2次中尺度对流复合体(MCC)的云图演变和环境物理量场特征分析,揭示了盛夏该地区MCC生成、发展的环境条件。结果表明:MCC发生在副高北侧深厚的高能舌、对流不稳定的气层中,500hPa东移短波槽是MCC的触发系统;高、低空急流和低层辐合场对MCC的生成和发展具有重要作用。

According to analyzing the two MCC cloud images and physics field by MICAP2.0. we know the conditions of creating and developing.
