- Latent heat release accompanying deep convection is critical in offsetting longwave radiative cooling in the middle and upper troposphere. 长波辐射造成的对流层中、上层大气的冷却则主要由深对流潜热释放来补偿。
- The coupling of upper and lower tropospheric jet streams is advantaged for causing strong convection, this is also one of factors of flood-resulting rainstorm in Linjiang area. 高低空急流耦合有利于强对流的发生和发展，是造成这次柳江致洪暴雨的重要因素之一；
- Not only are lary areas of the earth's land - sea surfaceinadequately monitored butdata gathering In the middle and upper troposphere is meager at best except ?in a few regions. 译为:不仅对地球上陆-海表面的广大地区的监视很不完整而且在对流层中部和上部(除少数地区外)收集到的资料充其量只能说是贫乏的。
- During the heavy rainfall in the upper troposphere the strong DPV and MPV tend downwards to the low-level, and vice MPV in the lower troposphere stretch up. 强降水发生期间，中高层强干湿位涡向低层传送，低层负湿位涡向上伸展。
- Not only are lary areas of the earth's land - sea surfaceinadequately monitored ,butdata gathering In the middle and upper troposphere is meager at best ,except ?in a few regions. 译为:不仅对地球上陆-海表面的广大地区的监视很不完整,而且在对流层中部和上部(除少数地区外)收集到的资料充其量只能说是贫乏的。
- There are favourable conditions in height and temperature fields for the vortex forming over the Plateau if the water vapor increases in the middle and upper troposphere over the west of India and Arabian Sea. 印度西部 -阿拉伯海上空对流层中上部水汽增加 ,可使高原上出现有利于低涡形成的高度场、温度场条件 ;
- The tropopause folding, which means that high PV spreads downward from the upper troposphere or stratosphere, helps the releasing of potential instability energy and the development of rainstorm. 对流层高层或平流层低层高位涡的下传有利于位势不稳定能量的释放，使得暴雨增幅。
- Therefore, it is not the advection process, but the vertical heating profile, which causes the atmospheric response in the lower troposphere out of phase with that in the upper troposphere. 因而阐明，不是由于平流作用，而是由于加热垂直梯度方向的改变，在加热中心下方产生正涡度强迫，中心上方产生负涡度强迫。
