Investigations of Tornadogenesis, Convection Initiation and the Evolution of the Convective Boundary Layer

许多气象现象受对流边界层的物理特性控制和/或影响。1991年在美国佛罗里达州举行的对流和降水/电气化实验（CaPE）中，使用了一系列非常先进的气象仪器来研究包括边界层在内的各种气象问题。首席研究员将利用CaPE的数据进行以下五个目标的研究：利用多普勒雷达和云摄影测量研究水龙卷；海风现象的详细分析，重点是天气流型、锋面变化和对流起始；边界层内发展的水平对流卷的演变，重点是增强云发展的沿卷变化；两边界碰撞引起的对流起生分析对气团风暴进行分析，以评估首席研究员最近提出的广义雷暴概念模式的普遍性。

Many meteorological phenomenon are controlled and/or influenced by the physics of the convective boundary layer. During the Convection and Precipitation/Electrification Experiment (CaPE) held in Florida in 1991, a collection of very advanced meteorological instrumentation was brought to bear on a variety of meteorological problems including those of the boundary layer. Using data from the CaPE, the Principal Investigator will conduct research with the following five objectives: study of a waterspout with Doppler radar and cloud photogrammetry; detailed analysis of the sea breeze phenomena with emphasis on synoptic flow regime, along front variation and convective initiation; evolution of horizontal convective rolls that develop within the boundary layer with emphasis on along roll variation of enhanced cloud development; analysis of convective initiation resulting from the collision of two boundaries; analysis of air mass storms in order toe assess the generality of a generalized thunderstorm conceptual model recently proposed by the Principal Investigator.
