Phys. Rev. E 70, 037301 (2004) [4 pages]1∕f model for long-time memory of the ocean surface temperatureReceived 27 August 2003; revised 3 February 2004; published 16 September 2004 The 1∕f spectrum of the ocean surface temperature in the Atlantic and Pacific midlatitudes is explained by a simple vertical diffusion model with a shallow mixed layer on top of a deep ocean. The model is forced at the air-sea interface with the total surface heat flux from a 1000 year climate simulation. The analysis reveals the role of ocean advection and substantiates estimates of internal thermal diffusivities. © 2004 The American Physical Society URL:
