Numerical Modelling of the Effects of Ozone on the Summer Atmospheric Circulation

The effects of ozone on the summer atmospheric general circulation are simulated by use of a zonal model with the p-sigma coordinate system. Results show that the simulated properties at the upper levels are remarkably im-proved after the ozone effects are introduced to the model. The direct effect of ozone is to enhance the heating rates at the upper levels. In the lower atmosphere, this effect is very little. Furthermore, the ozone can change the distributions and values of other components of heating fields, resulting in the change of the total heating rates, and meanwhile induce evident variation of atmospheric circulation at the lower levels.
