摘要
针对驻马店2010—2012年出现的54次短历时强降水过程,研究了其时空分布特征、天气背景和环境条件,从形成机制上将其分为暖区对流系统和锋面对流系统两类,同时对短历时强降水的天气雷达产品如反射率因子、径向速度场、垂直积分液态含水量、风暴跟踪信息等特征进行了详细的分析,并以此建立短历时强降水的物理模型;对预报中的失误之处进行反查,整理出了此类天气的天气模型和预报思路,为以后准确预报短历时强降水天气提供科学借鉴.
According to the 54 short-duration strong precipitation process in Zhumadian from 2010 to 2012, their temporal and spatial distribution characteristics, weather background and environmental conditions are studied. The formation mechanism is divided into the warm convective systems and the frontal convective system,meanwhile the radar products such as reflectivity, radial velocity field, vertical integrated liquid water, the characteristics of storm tracking information are analyzed in detail. The short-duration strong precipitation physical model is established. The forecast failures is reverse checked, and the weather model and forecast thought of this kind of weather is finished, providing the scientific references for accurate prediction of the short diachronic strong precipitation.
