臭氧对夏季大气环流影响的数值模拟

利用球带ｐ－σ坐标系模式，模拟了臭氧对夏季大气环流的作用，结果表明，臭氧作用引入模式后，大气高压环流特征得到显著改善，臭氧使高层大气的加热率增大；对低层大气，虽然臭氧的加热作用很小，但可通过改变其他加热场分量的分布和量值，从而改变总加热率，使低层大气环流同样发生变化。

NUMERICAL MODELLING OF OZONE EFFECT ON SUMMER ATMOSPHERIC CIRCULATION

The effects of ozone upon summer circulation in the atmosphere are simulated interms of a zonal model in a pa coordinate system,Results show that the upper-level circulationfeatures are improved substantially after the ozone effects are introduced into the model.The in-volved effects enhance the heating rate at upper levels and for the lower atmosphere ,despite itsnegligible heating there the gas is capable of altering the distributions and values of other heatingcomponents,thereby causing the lower-level circulation to undergo corresponding change.
