Abstract:
Area: Eastern Pacific Understanding the fundamental processes of air–sea interaction and advective terms under greenhouse scenarios in the eastern pacific with particular emphasis in the Humboldt Current and Panama bight systems. Abstract: The seasonal cycle of oceanic and atmospheric variables is the key variable of the global climate system. Yet little attention has been paid to the response of the eastern pacific and particularly south pacific to anthropogenic climate change. We wish in the following to complete this need by investigating the changes in the heat balance of the oceanic surface layer (air-sea processes and advective terms), at the seasonal time scales which may be influenced by the forcing of greenhouse gases at secular time scales in the eastern pacific with particular emphasis in two areas. The Panama bight and is associated regions which are located north of the equator (9N-1S, 100W-78W) and the Humboldt Current (2S-40S, 90W-east). Objectives: Compare the seasonal cycle for shortwave and longwave radiation, sensible, latent, and net heat fluxes available from four products in order to gain an improved understanding of the characteristic of the Humboldt Current and Panama Bight System spatial patterns, their seasonal structure, and how they evolve forced by greenhouse gases and other forcing under different scenarios.
