General information and objectives

The CMP is designed to foster the development of 3-dimensional atmospheric climate models and the refinement of parametric formulations of important physical processes used in models. Improvements in data assimilation methods will also be pursued. The CMP includes numerical climate simulation and experimentation programs, climate model development and periodic intercomparisons of various aspects of model performance, the assessment of model errors, and reviews of advances in data simulation and the results thereof. These activities are conducted under the following projects (WMO,1994, see below):
  • Global coupled climate modelling (WCRP Steering Group on Global Climate Modelling, SGGCM):
    In 1994 the SGGCM compared the 15 existing CGCMs and reviewed the major problems associated with CGCMs (representation of clouds, surface flux adjustments/corrections, problemd with the initialization and "spin up" of the ocean component, treatment of sea ice, meridional ocean heat transport, vertical penetration of heat into the sea, spatial resolution and simulation of climatic variability).

  • Atmospheric modelling (CAS/JSC Working Group on NUmerical Experimentation, WGNE):
    This activity focuses on model intercomparisons and analysis of different representations of atmospheric and land surface processes, as well as of model predictions (e.g. of precipitation).

  • Modelling large-scale atmospheric tracer transport:
    Series of scientific workshops to improve the parameterization of sub-grid scale tracer transport and to compare standard numerical experiments. The focus for the 1995 workshop will be on the parameterization of scavenging of trace constituents and aerosols by clouds.
