Phys. Rev. Lett. 90, 108501 (2003) [4 pages]Scaling of Atmosphere and Ocean Temperature Correlations in Observations and Climate ModelsReceived 4 September 2002; published 11 March 2003 Power-law scaling of near surface air temperature fluctuations and its geographical distribution is analyzed in 100-yr observations and in a 1000-yr simulation of the present-day climate with a complex atmosphere-ocean model. In observations and simulation detrended fluctuation analysis leads to the scaling exponent α≈1 over the oceans, α≈0.5 over the inner continents, and α≈0.65 in transition regions [spectrum S(f)∼f-β,β=2α-1]. Scaling up to decades is demonstrated in observations and coupled atmosphere-ocean models with complex and mixed-layer oceans. Only with the complex ocean model the simulated power laws extend up to centuries. © 2003 The American Physical Society URL:
