摘  要:
利用气象数值产品、自动观测站资料、卫星云图和多普勒雷达资料,分析诊断2010年6月30日安阳局地暴雨、大暴雨过程的环流形势场特征与中小尺度物理量的热力学、动力学以及雷达回波特征。结果表明,自动观测站资料的变化能很好地反映地面辐合线的变化情况;径向度不断加大的西南气流为强降水提供了充足的水汽;近地层的偏东气流的入侵以及前期的地面不断增温为强降水提供了高的不稳定能量;降水愈强则凝结潜热释放愈多,对中尺度辐合的发展起促进作用。

摘  要:
Numerical weather products,automatic observation station data,satellite images and Doppler radar data were used to analyze circulation situation field characteristics during storm,heavy rain process and thermodynamics,dynamics and radar echo characteristics of meso-and micro-scale physical quantity on June 30,2010 in Anyang,the results indicate that the changes of automatic observation station data can be well reflected in changes in surface convergence line with the changes and movement of rain trends;ever-increasing radial flow for the heavy rainfall in the southwest provided sufficient moisture;surface layer easterlies ground invasion and pre-warming for the heavy rain continued to provide a high energy unstably;the stronger the precipitation generated the more the release of latent heat of condensation,which played a driving role for the development of meso-scale convergence.
