Numerical Simulation of World Ocean Effects on Temperature and Ozone in the Lower and Middle Atmosphere

A. R. Jakovlev and S. P. Smyshlyaev

The description of the ocean–atmosphere coupling is presented. The paper analyzes the data of MERRA, JRA, ERA-Interim, and ERA-20Century reanalyses and the results of CCM chemistry-climate model simulations based on monthly mean values of air temperature and ozone mixing ratio at the levels of 925 and 20 hPa during 1980–2015. The comparison with data on sea surface temperature is provided. The results of simulation are in good agreement with reanalysis data for the atmospheric surface layer, whereas essential differences for the stratosphere require a more detailed analysis. According to the model results, air temperature rises in the surface layer, and air temperature and ozone mixing ratio decrease in the stratosphere. Reanalysis data do not contradict simulation results for the troposphere but differ significantly for the stratosphere.
