There are a variety of cloud processes that affect the large-scale behavior of the climate system, but occur on scales too small to be represented explicitly in global numerical models used for climate and weather prediction. Scientists develop numerical representations or parameterizations to represent the behavior of these processes. It is generally recognized that inadequate parameterization of clouds is one of the greatest sources of uncertainty in the prediction of weather and climate. The GEWEX Cloud System Study (GCSS) will develop better parameterizations of cloud systems for climate models by an improved understanding of the physical processes at work within the following types of cloud systems:
Extra tropical layer
One method for testing parameterizations is called Single Column Modeling. GCSS working groups representing each of the cloud systems under study, will perform the following activities:
