Abstract
A two-dimensional model for ozone changes by the planetary wave in the stratosphere is formulated. It is found that the temperature wave may reduce the zonal mean value for the photochemical loss rate of ozone through the temperature effect. This reduction in the photochemical loss owes substantially to the strong negative correlation between the ozone concentration and temperature, and results in an enhancement of the zonal mean ozone concentration. Such an effect has not been presented in the previous models. This effect is evaluated to find that a 50% enhancement of the zonal mean ozone concentration can be produced by the temperature wave of 15°K amplitude when the zonal mean temperature is 240°K.
