Abstract:

地面中尺度自动站和多普勒雷达资料的分析都表明,台风Matsa登陆后的低层螺旋云带中活跃着中尺度气旋性涡旋系统。本文使用新一代中尺度WRF模式对台风Matsa登陆后的变化特征进行了数值模拟,使用四维变分多普勒雷达分析系统(4D-VDRAS)对台风Matsa多普勒雷达径向风进行了风场反演。在此基础上对台风Matsa登陆后中尺度扰动特性进行了初步探讨;对台风Matsa与其螺旋云带的中尺度系统之间动能和涡度的相互转换进行了诊断分析。分析表明:(1)数值模拟和雷达风场反演结果表明,登陆台风Matsa的低层螺旋云带中活跃着中尺度气旋式涡旋系统,与之相伴随的为较强的中尺度上升区,而且,中尺度垂直上升运动的强弱与雷达对流回波强度成正相关,中尺度垂直上升运动越强,雷达对流回波发展越旺盛。(2)台风Matsa与其中尺度系统动能转换的诊断分析说明,低层中尺度系统从台风Matsa环流中获得动能而发展;Matsa在陆地上长久维持主要是从高层获得动能。(3)台风Matsa与其中尺度系统涡度转换的诊断分析说明,低层中尺度系统向Matsa输送正涡度主要依靠中尺度垂直运动来完成;高层正涡度的转换通过水平输送和垂直输送共同来完成。所以,中尺度系统所产生的正涡度源源不断地向Matsa输送,使Matsa的气旋性环流可以在陆地上长久维持。
