Abstract
The model system of regional climate model linked with atmospheric chemical model is applied to simulate the response of variation of the vertical distribution of the tropospheric ozone to the intensity of emission from biomass burning in South Asia.The result shows that the integrated vertical ozone concentration of the troposphere is very sensitive to the intensity of the burning emission at source regions,increased with a greater rate than in downwind regions of the lower and middle troposphere,but with the same rate as in the middle and upper troposphere.Increase of ozone occurs earlier in the lower troposphere than the lower parts of the source regions and the foregoing decreases with height,but lags in the middle troposphere,and takes place in the same duration in the upper troposphere.
