These results were obtained from a multi-century control experiment which was performed to simulate the natural variability of the coupled system. The model reproduces the observed annual the temperature cycle well. Note that the amplitude of the annual cycle is much larger over the poles and extra-tropical land areas than over the oceans. You might also notice dfference in the shape of the annual cycle which reflects the different thermal properties of the land, ice and water covered parts of the Earth's surface.

The data from the multi-century control simulation with the coupled model are available for downloading from our data section.
