Comparison of CCM3 simulations using two climatological ozone data sets
A comparison of two six year simulations with the CCM3 using different monthly mean, zonally symmetric ozone climatologies is presented. Each run was identical except for the ozone specification. The climatological SSTs supplied with CCM3 were cycled for the extent of the simulation. The ozone data...

A comparison of two six year simulations with the CCM3 using different monthly mean, zonally symmetric ozone climatologies is presented. Each run was identical except for the ozone specification. The climatological SSTs supplied with CCM3 were cycled for the extent of the simulation. The ozone data sets were used were the data distributed with the CCM3 code and that compiled at SUNY Albany. The SUNYA data set reflects contemporary ozone measurements extensively using remote sensing data. The CCM3 data were produced from measurements prior to 1974. A brief comparison of the two ozone climatologies is presented. The monthly mean difference fields were computed for the six years of the simulations. A t-test was applied to the monthly mean difference to judge if the changes between the integrations were significant. The significant changes in temperature were for the most part confined to the levels above 200 hPa. In the zonal mean the patterns of differences were largely consistent with regions of the ozone variations, deeper tropospheric penetration of temperature difference occurred in October near the South Pole in the region of the `ozone hole`. The significant temperature changes at the lowest model level (approximately 992 hPa) were confined to very small areas. The 200 hPa zonal wind differences demonstrated that the stationary wave structure was evidently altered by the ozone difference. Although the ozone specifications were zonally symmetric, the zonal wind differences were zonally asymmetric at 200 hPa. |
