| 摘 要： | 2005年4月20日,哈尔滨新一代天气雷达观测到东北冷涡内部具有中尺度的变形场结构,即在雷达速度图上,存在两负两正且互为准对称的现象.在变形场中通常会引起锋生效应,而雷达观测具有高时空分辨率,可以及时发现这种中尺度的变形场.本文应用实时雷达资料,配合卫星云图及常规资料场,对该次过程进行分析.说明变形场在冷涡发展的过程中起到了重要作用.

| Abstract: | On April 20,2005, a mesoscale deformation field structure in cold vertex was found in the Doppler velocity picture which showed a symmetrical structure. Frontogenesis was usually caused in the deformation field which could be found timely in radar observation with high spatial-temporal resolution. By using the real-time radar data, satellite image and conventional data. the synoptic process was analyzed. It indicated that the deformation field played an important role in the course of development of the col... |
