General information and objectives

The goal of GEWEX is to reproduce and predict, by means of suitable models, the variations of the global hydrological regime, its impact on atmospheric and surface dynamics, and variations in regional hydrological processes and water resources and their response to changes in the environment, such as the increase in greenhouse gases. GEWEX will provide an order of magnitude improvement in the ability to model global precipitation and evaporation, as well as accurate assessment of the sensitivity of atmospheric radiation and clouds to climate change.

Research Foci: GEWEX is composed of several components designed to address the elements of the scientific focus, the global energy and water cycle.
  • Radiation - Determine atmospheric and surface radiation fluxes and heating with the precision needed to predict transient climate variations and decadal-to-centennial climate trends.
  • Hydroclimate - Demonstrate skill in predicting changes in water resources and soil moisture on time scales up to seasonal and annual as an integral part of the climate system.
  • Modelling and Prediction - Develop accurate global model formulation of the energy and water budget and demonstrate predictability of their variability and response to climate forcing.
