| 摘 要： | 2010年5月2日伊犁地区出现持续降水、雷暴较强天气过程。利用常规高空、地面观测资料和新一代天气雷达资料系统地分析此次天气中环流背景、物理量场、云图、雷达回波的演变特征。分析得出,这次大降水是西伯利亚至咸海槽区,咸海和巴尔喀什湖之间以南一短波槽这2个系统共同配合的系统性天气;丰富水汽条件并有持续的水汽输送是产生大降水的必要条件;垂直抬升运动与地形的作用是造成这次大降水天气的直接原因。 |

| Abstract: | 0n 2 May 2010 yili area appeared last precipitation, thunderstorm strong weather process. This paper by using conventional high altitude, ground observation data and a new generation of weather radar data systematically analyzed the weather general circulation background, physical field, cloud, the evolution of the radar echo characteristics. Analysis, the great rainfall is Siberia to while slot area, while south of lake kashgar and baal between a short wave trough the two systems with systemic together the weather; Rich moisture conditions and for water vapor transmission is a necessary condition of great rainfall; Vertical lifting movement and the role of the terrain is caused the great rainfall weather directly responsible. |
