Results from simulations with the coarse-resolution version of MPI-ESM performed by the RETRO team at DKRZ. The left side shows a normal (prograde) rotating earth. The right side shows a backwards (retrograde) rotating earth. The simulations are forced with pre-industrial boundary conditions. For the full description see the Earth System Dynamics manuscript "The climate of a retrograde rotating earth". The zonal wind patterns are reversed in the retrograde simulation (right), resulting in easterly jets and westerly trade winds. Therefore, continents in the subtropics and mid-latitudes become colder on their western and warmer on their eastern margins. The storm track in the South Pacific is more pronounced, which is related to the changes in ocean circulation, specifically the subtropical gyre in the South Pacific.
