Abstract:
Observation shows that the complex of stratiform and embedded convecti ve percipitation has its own unique thermal and dynamic structure, and the preci pitation process has its own characteristics. However, the numerical study of real cases has been published much less so far. In this paper, a case on the 28 September 2007 complex of stratiform clouds and embedde d convective clouds in North China is simulated by using the WRFARW model. It shows that, the clouds are weakened by the shear line, and formed by the develop ment ofstratiform clouds. It also reveals that the complex of stratiform clouds and embedded convective clouds is not only the comp lex of clouds with different shapes, but also the complex of different microphys ical processes. And the largescale convergence on the middle level and the cor responding uniform updraft make the stratiform clouds develop, while the dramatic fluctuations of updraft lead to embedded convective clouds, which may be initiated and supported by conditional symmetric instability.
