Combined with the analysis of physical parameters, two kinds of conceptual models of typical regional heavy rainstorm systems about strong frontal zone and warm vortex are found.
结合物理量场的分析，建立了强锋区和暖涡旋两类典型特大暴雨系统的概念模型。
Tornadoes form when the updrafts of air that supply storms with warm, humid air become a vortex, or high-speed whirlwind.
当上升气流与能形成风暴的湿热空气变成高速的旋风时，就形成了龙卷风。
For example, a non-geostrophic vortex in wind field on the 375 MB level can result in a high with the warm center in the troposphere and the cold center in the stratosphere.
例如375毫巴上单纯非地转风的流场的反气旋涡旋，适应后可建立起对流层暖性、平流层是冷性的高压系统。
Tornadoes form when the updrafts of air that supply storms with warm humid air become a vortex or high-speed whirlwind.
当上升气流与能形成风暴的湿热空气变成高死锬旋风时，就形成了龙卷风。
The heavy rainfall is dominated by a mesoscale warm shear line, having a closed relationship with a mesoscale system composed by mesoscale shear line, thunderstorm high and mesoscale vortex;
这次强降水与中尺度切变线、雷暴高压和中尺度气旋等中尺度系统关系密切，为一次中尺度暖式切变线暴雨过程；
