中文摘要	利用新疆喀什地区13个县(市)1962-2012年51 a来冰雹天气时序资料及喀什市探空站资料,采用统计、M-K检验等方法进行冰雹时空分布特征和环境条件分析。结果表明:喀什地区冰雹日数总体呈逐年增加的趋势,年内冰雹天气表现出显著的年代振荡特征; 空间分布差异较大,大致为北多南少。局地性冰雹明显多于系统性冰雹。冰雹发生的季节分布呈单峰型,高发期在5-7月。冰雹发生前垂直风切变、湿对流能量及整层水汽积分必须同时满足一定条件,缺一不可; 0℃层高度和-20℃层高度之间的厚度越小越有利于产生大雹。主要天气型为中亚低槽(涡)、不稳定短波槽和南北槽叠加3类,中亚低槽(涡)和不稳定短波槽过境是触发系统性冰雹、局地性冰雹的重要影响系统。
英文摘要	Kashgar region,taking agriculture as the body of regional economy,is one of the country’s largest regional commodity cotton base and the famous melons and fruits township. Located in the border of Gobi,desert and oasis,the hail frequency is higher,disaster heavier,causing serious damage to the local farming and animal husbandry production,the successful hail short-time and short-term forecasting is of great significance to guide the hail proof operation. Using the time series data for hail weather of 13 counties (city) and information of Kashi radiosonde stations from 1962 to 2012,the authors analyzed the spatial and temporal distribution characteristics and environmental conditions of hail through statistical analysis method,M-K testing. The results show that,hail days showed an increasing trend year by year as a whole; hail weather shows significant interdecadal oscillation characteristics with a year; the spatial distribution is very different,more in northern part and less in southern part in Kashi area. The local hail is more than systematic hail. The seasonal distribution of hail was unimodal,high value period in from May to July. Before the hail,vertical wind shear,moist convective energy and water vapor integral must meet certain condition at the same time and none is dispensable; the smaller thickness between 0 ℃ to-20 ℃ layer height is more conducive to produce large hail. The main weather type include the Central Asian Low Trough (vortex) ,unstable short-wave trough,south and north trough superimposed,the Central Asia low trough (vortex) and unstable short-wave trough transit is the important influence system triggering systematic and local hail.
