摘要
用单部多普勒雷达观测资料,使用Browning,Hobbs等人和Locattelli等人的方法,计算了冬季极地气团涡旋内中尺度雨带法向垂直面上的二维流场和热力平流。得到的结果定性地和雨带的存在及不同发展阶段一致,和探空仪观测的结果基本一致,但是在定量的意义上本文得到的垂直速度偏高,冷暖平流区也非全部一致。用不同的方法处理资料得到的二维流场有明显变化。
2 -D flow fields and thermal advection on the normal plane of mesoscale rain bands in the winter polar air mass vortex have been calculated by using single Doppler radar data and the method following Browning and Hobbs and others. Results are qualitatively agreement with the existence of rain bands and their different developing stages, also basically agreement with radio sounding. However the value of vertical velocity obtained seems too large and cold and warm advection areas are not totally consistent. Results also change remarkably with the different methods of data processing.
