Abstract
This paper analyzed the process of heavy rain which happened on July 24 to 27 2010 at southeastern coast of Zhejiang, Wenzhou, Taizhou, Ningbo, Zhoushan et al., and discovered that the continuous heavy rain is caused by the easterly waves. The interaction of Western Subtropicaol High heat convection cloud with the easterly waves and the low vortex induced by wave were also important persistent heavy rain; At the same time, the uplifting effect of the Tiantai Mountain and Kuocang mountain, along with the narrow tube effect at the coastal horn-type Harbour also played an important role. We pointed out that it's a profound easterly wave with big northe-south amplitude, long duration and high height extending up to 200 hPa. The structural features are:low-level trough before the divergence, high-level convergence, after the trough of low level convergence together high-level divergence; wave front sinking motion, upward motion after the wave.关键词
