WP2: Climate model Evaluation and Analysis


In Work package 2, we will analyse the CMIP5 climate simulations executed in WP1, in support of the 5th Assessment Report of the IPCC, by climate and weather prediction GCMs. The aim of our analysis will be two-fold:

  • To evaluate the ability of GCMs to reproduce the observed climate, with a particular focus on clouds, precipitation and radiation, and to relate errors associated with the simulation of some critical climate phenomena, e.g. the structure of the ITCZ, tropical climate variability at intra-seasonal and inter-annual timescales, temperature extremes over Europe, to the simulation of specific cloud or moist processes.
  • To analyse the climate change simulations performed by the same models to assess the uncertainty in projections of future cloud and precipitation changes, and to understand the physical processes underlying this uncertainty.
For this purpose, WP2 will use the tools and the methodologies developed in WP1 and in interaction with WP3 and WP4, will contribute to develop and propose modelling and observational strategies to improve the predictive skill of climate and weather prediction models.

WP2 is chaired by Sandrine Bony
