中文摘要:
      本文应用片段位涡反演方法和中尺度WRF模式研究了2016年01号台风“尼伯特”对一次梅雨锋降水的影响,研究结果表明:减弱(增强)台风之后,降雨区的水汽通量增加7.34%(减弱6.67%),动能增幅7.78%(减弱5.36%),对流有效位能增幅达到6.66%(减弱5.71%)。江淮地区降雨量出现累积降雨量增幅10.21%(减幅8.13%)。台风“尼伯特”在其加强、靠近中国大陆的过程中,迫使副高北抬东撤,阻碍了沿副高边缘输送至江淮地区的水汽和热量,间接导致该地区降水显著减少至消失;此外台风增强过程中,本体环流对于水汽和能量的消耗增大,导致孟加拉湾输送至江淮降雨区的水汽和能量的减少,直接导致梅雨锋降水过程中止。
Abstract:
      The effects of typhoon on the precipitation of Meiyu front are studied by using the fragment inversion method and the mesoscale WRF model. The results show that the water vapor flux in the rainfall area increases by 7.34 % (6.67%), kinetic energy increase of 7.78% (weakened 5.36%), convective effective bit energy growth of 6.66% (weakened 5.71%). The accumulated rainfall in the Jianghuai area increased by 10.21% (8.13%). Typhoon "Nibert" in its strengthening, close to the Chinese mainland in the process, forcing the north side of the north side of the subtropical high, hindering along the high edge of the transport to the Jianghuai area of water vapor and heat, indirectly, the area significantly reduced to the disappearance of precipitation; In addition, during the process of typhoon enhancement, the water circulation and energy consumption of the main body circulation increase, which leads to the decrease of water vapor and energy delivered to the Jianghuai rainfall area, which leads directly to the precipitation process of Meiyu front.
