污染物大尺度垂直输送的理论研究

从大尺度动力学的观点讨论了污染物进入自由大气后的垂直输送问题， 重点讨论了绝热条件下中性波及斜压不稳定波引起的垂直运动对污染物的垂直输送以及非绝热情况下由剩余环流引起的垂直运动对污染物的垂直输送， 并从波作用对垂直运动贡献的观点，指出了平流层内由于波作用引起的非局地的下沉运动对污染物垂直输送的控制作用， 最后还指出以往对垂直运动诊断研究的一些成果也是对污染物垂直输送有贡献的因素。

Large-Scale Vertical Transport Theoty of Pollutants

In the paper, from viewpoint of large-scale dynamics, the vertical transport of pollutants after being pumped into free atmosphere is discussed Especially, both the vertical transport of pollutants induced by neutral wave and baroclinic instability wave under adiabatic condition and diabatic heating are emphasized And then from viewpoint of the contribution of wave action to the vertical motion, the controlling function of the non-local descending motion to pollutants transport in the stratosphere is mentioned In the end, it is pointed out that the previous diagnostic study of the vertical motion is also an unnegligible factor to pollutants transport
