地形抬升和热源强迫在臭氧经向突变过程中可能的作用

The Roles of Both Topographic Lifting and Heating in the Forming of Meridional Cataclysm of Total Ozone

本文利用二层准地转截谱模式,考虑30°～35°N纬(?)带上的大地形抬升和热力强迫两类作用,讨论了Hadley基本流型的分支,解释了臭氧突变现象,本文还指出突变应是整个北半球的普遍现象;是热力与动力作用的共同产物.最后,还用臭氧观测资料对此作了初步的验证。

The roles of topographjc lifting and heating in the forming of meridional cataclysm of the atmospheric ozonosphere are discussed by using a two-level guasigeostrophic truncated spectral model.It is shown that the ozone cataclysm may be a commen phenomenon in the whole northern hemisphere,and the result of both dynamical and thermal forcing of plateaus in the zone between 30-35° N.
