The Coordinated Regional climate Downscaling Experiment (CORDEX) is a program sponsored by the World Climate Research Program (WCRP) to organize an international coordinated framework to produce regional climate change projections world-wide for input into impact and adaptation studies. CORDEX aims to build a common set of domains for statistical and dynamical downscaling and seeks to establish a standard set of variables, frequency as well as format for output and archival at a number of data centres.
CORDEX-Latin America and the Caribbean (LAC) is one of fourteen domains identified in Phase 1 of CORDEX. The domain presents a unique mix of continental territories and island chains of differing size, shape, topography and orientation spanning deep tropics and subtropics. Regional climate is influenced dominantly by the subtropical high of the north Atlantic with influences from the Intertropical Convergence Zone, polar fronts from the midlatitudes and westward propagation of transient systems such as tropical storms and hurricanes. The interplay between ocean temperatures over the Atlantic and Pacific is also important to the region. The domain therefore presents a complex and diverse area for application of statistical and dynamical modelling.
