Session A1: Earth System Modelling in the regional context

Tuesday 26 September 11.00-12.30 CEST

Location: Sissa Main Auditorium

Session co-chairs: Melissa Bukovsky and Klaus Görgen
Rapporteurs: Daniel Abel and Henri Pinheiro

Earth System Modelling (ESM) in the regional context can integrate two-way coupled processes to include dynamic vegetation (carbon cycle), oceans (and sea-ice), atmospheric chemistry, lakes and glaciers, biogeochemistry, etc. It can be used to demonstrate that Regional Earth System Models (RESMs) are able to improve the capability of simulating regional climate features. Key questions: Is there any added value of RESMs compared with RCMs? Is there any compromise between complexity, resolution and domain size?  Should a CORDEX-MIP on RESMs examining the regional response including a variety of coupled components to the RCMs be explored? WCRP Core Projects, Light House Activities, CORDEX FPSs.
