| 英文摘要 | The cumulus merging processes in generating the mesoscale convective system (mcs) on 23 august 2001 in the beijing region are studied by using a cloud-resolving mesoscale model of mm5. the results suggest that the merger processes occurred among isolated convective cells formed in high mountain region during southerly moving process play critical role in forming mcs and severe precipitating weather events such as hailfall, heavy rain, downburst and high-frequency lightning in the region. the formation of the mcs experiences multi-scale merging processes from single-cell scale merging to cloud cluster-scale merging, and high core merging. the merger process can apparently alter cloud dynamical and microphysical properties through enhancing both low- and middle-level forcing. also, lightning flash rates are enhanced by the production of more intense and deeper convective cells by the merger process, especially by which, the more graupel-like ice particles are formed in clouds. the explosive convective development and the late peak lightning flash rate can be found during merging process. |
