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". Monthly surface temperatures show the differences in the seasonal cycle. The most prominent differences are evident over South America and the Sahara during the Northern Hemispheric summer and western Europe and the North Atlantic during winter. The simulations also show that east-west temperature gradients over continents are reversed in the retrograde simulation (right) and are pronounced over North America and South Africa.
