En: Advances in Meteorology Vol. 2013 (June 2013), p. 1-18Tema: The regional impact of global climate change on the ocean circulation around the Galapagos Archipelago is studied using the Hybrid Coordinate Ocean Model (HYCOM) configured for a four-level nested domain system. The modeling system is validated and calibrated using daily atmospheric forcing derived from the NCEP/NCAR reanalysis dataset from 1951 to 2007. The potential impact of future anthropogenic global warming (AGW) in the Galapagos region is examined using the calibrated HYCOM with forcing derived from the IPCC-AR4 climate model. Results show that although the oceanic variability in the entire Galapagos region is significantly affected by global climate change, the degree of such effects is inhomogeneous across the region. The upwelling region to the west of the Isabella Island shows relatively slower warming trends compared to the eastern Galapagos region. Diagnostic analysis suggests that the variability in the western Galapagos upwelling region is affected mainly by equatorial undercurrent (EUC) and Panama currents, while the central/east Galapagos is predominantly affected by both Peru and EUC currents. The inhomogeneous responses in different regions of the Galapagos Archipelago to future AGW can be explained by the incoherent changes of the various current systems in the Galapagos region as a result of global climate change.
