摘  要:
利用常规观测资料、新一代多普勒雷达资料、自动站资料,对锦州地区一次雨转暴雪过程的发生、发展机制及降水相态转换的温度进行分析,结果表明:此次暴雪过程是500 hPa高空槽、850 hPa低涡及地面倒槽共同作用的结果。西南和东南急流在辽宁省上空形成较强的水汽辐合,强降雪落区位于急流汇合处,雨雪转换过程中,地面气温和近地层的温度与降水相态关系密切。

摘  要:
Based on the conventionally observational data,meteorological data from automatic weather stations and Doppler radar data,a rain to heavy snowstorm weather process in Jinzhou was analyzed.The results showed that the major influencing system of this heavy snowfall was the 500 hPa trough,vortex at the level of 850 hPa and the surface inverted trough.Southwest jet and Southeast jet form the strong water vapor convergence in our province over,heavy snowfall area was located at the confluence of the low-level jet in the conversion process between the rain and the snow,ground and surface layer temperature have a close relationship with precipitation phase.
