| 摘 要： | 运用常规天气图、物理量场、新一代多普勒天气雷达回波图、四要素气象自动站等相关资料,对2010年6月17日夜里发生在安阳的一次冰雹伴随短时强降水的强对流天气进行中尺度天气分析.结果表明:高低空有利形势的配置、地面辐合产生强烈上升运动,进而引发不稳定能量的释放,是这次中尺度对流性天气形成的直接原因.地面辐合线能准确预示对流... |

| Abstract: | By using conventional weather chart,physical field,new general Doppler weather radar echo features and 4-factor automatic watching station data,it analyzes a meso-scale convective hail storm coupled with on 17 June 2010 in Anyang Henan.Result indicates that the direct reason of the meso-scale storm is the releasing of instability energy in the advantageous ordonnance from low to high,caused by surfacial convergence produced intense rising.Further more,it shows that surfacial convergent line predictes the area convection occurred,the abrupt inflexion on VIL(vertical integrated liquid water)is significative to illuminate the progress of hail come into being and the time hail landing accurately,the centre of cyclonic convergence is the area the most flourishing convection lies and the most possible point hail lands. |
