O_3和海温对七月中、低纬环流的影响

EFFECTS OF OZONE AND SST ON THE UJLY CIRCULATION AT MID AND LOW LATITUDES

在原球圈范围的Ｐ－σ坐标模式中加入了Ｏ３和海洋混合层的影响，对７月中、低纬流场进行了数值模拟试验．第１种方案中包含了Ｏ３，第２种方案既包含了Ｏ３又引入了海洋混合层．将这两种方案与原方案（不包含Ｏ３和海洋混合层）流场的模拟结果作对比分析发现１、２方案模拟结果比原方案更接近实况，特别是第２种方案模拟效果更加理想．表明Ｏ３和海洋混合层对大气环境的影响是重要的，它不仅直接影响到海洋，对陆地也有重要影响．其影响不只是局限于大气的低层。

The effects of the ozone and the sea surface temperature (SST) in the ocean mixing layer are included in the original version of the Psigma model with a zonal domain. The new version of the model is used to simulate the July circulation at the mid and low latitudes. In the first experimental scheme, only the ozone effect is included, while in the second both of the effects of the ozone and the SST are contained. The results of the above two schemes are compared with those of the original scheme in which there are no effects of the ozone and the ocean moxing layer SST. It is fond that the results of the new schemes are closer to the observations than those of the old ones. Especially, the second scheme impoves the simulations at the high and the low atmospheric levels to a larger extent. The analyses point out that the effects of ozone and SST in the ocean moxing layer on the simulations are important. The inclusion of the ocean moxing layer influences not only idrectly the atmopheric circulation above the ocen, but also the circulation over thd land. Such an effect is not omly limited to the low levels of the atmosphere, the effects on the high levels are evident, too.
