摘要
为了充分发挥新一代天气雷达在乌鲁木齐南山山区的探测作用,利用2003—2005年6—9月101次出现降水的雷达回波资料以及对应天气形势和地面实况,分析得出乌鲁木齐南山中山带对流云的回波顶高、强度、出现的时段、性质等参数特征和演变规律,从宏观上为该地区对流云人工增雨作业及短时预报提供科学依据。
To focus on sufficiently exerting the detectible function of the new generation synoptic radar in the Nanshan mountain area of southern Urumqi, by using 101 times radar echo data of precipitation and the corresponding synoptic situation and surface observation from 2003 to 2005 during Jun.-Sep., the characteristics of parameters and evolutive regularities of convective cloud in the mid-mountain region of southern Urumqi were analyzed in this study, including the echo top, and its intensity, occurrent periods, nature etc.. And provided a scientific basis of macro view for artificial rainfall of convective cloud and short-time forecast in that region.
