Outline of Final Research Achievements |
Numerical experiments using atmospheric general circulation models are conducted with “Aquaplanet” lower boundary conditions where whole of the earth’s surface is covered with ocean. Main findings are as follows. First, a westward propagating large scale organization of precipitation with north-south "zigzag" structure is newly identified, in addition to the well known eastward propagating structure. Second, the structure of 'Walker circulation’, a global stationary circulation feature forced by the anomaly of sea surface temperature, is highly sensitive to the average north-south surface temperature difference of the ocean. Sensitivity of both results to the model specification including physical parameterizations and spatial resolution promotes a new international aquaplanet general circulation model intercomparison project, APE2.
