CLIVAR/GEWEX Monsoons Panel

About Us

Regions where at least 70% of annual precipitation occurs in the 5-month seasons indicated.

This is only one of many possible definitions of monsoon regimes around the globe. Data are from GPCP version 2.5 For 1979-2008 provided by P. Dirmeyer


Monsoons are a global phenomenon and overall progress in our scientific understanding of monsoons will benefit by the interaction of individuals and groups that study these various regions. Furthermore, the efforts of the Global Water and Energy Exchanges (GEWEX) project are highly relevant to the terrestrial and hydro-thermodynamic aspects of monsoons. As a result, a single Monsoons Panel spanning both CLIVAR and GEWEX has been formed with membership drawn from both communities. The new panel will report to both CLIVAR and GEWEX Scientific Steering Groups.

Working groups under the new panel will continue to lead the regionally-focused monsoon research in each of the three areas of globe. Meanwhile, the new panel is defining concrete activities to be fostered in the coming years, coordinating the regional working groups, and acting as a hub to facilitate meetings and linkages among international research efforts. Advancing understanding of monsoon variability and improving prediction remain the principal goals promoted by the new Monsoons Panel, but greater emphasis is being placed on linkages across scales and to phenomena that have historically been outside the purview of classical monsoon research. Observation and modeling are still the cornerstones of the research efforts, but we seek to bring new methods and fresh perspectives to the problem that can enhance monitoring, advance diagnostic efforts, and improve component and coupled models.

Key to these efforts will be the development of new and better process studies, coordination with relevant modeling efforts including those related to climate change, and empowering the next generation of bright young scientists from around the world to advance our knowledge of monsoon systems.

The Monsoons Panel is supported by Dr Rokkam Rao and staff of the International CLIVAR Monsoons Project Office (ICMPO) hosted by the Indian Institute of Tropical Meteorology (IITM) located in Pune, India. ICMPO is the node of  International CLIVAR Project Office (ICPO). This arrangement is part of the newly established distributed ICPO, designed to take advantage of the strengths of the participating institutions and fostering an ICPO that is truly international in nature.


Terms of Reference

  1. During first year, define concrete activities to be fostered by the panel within the next 3-5 years.
  2. Evolve a strategy to assess the current levels of predictive skill of the coupled ocean-atmosphere-land system in the monsoon regions;
  3. Design and implement a means to investigate the interactions between climate mean state and different modes of monsoon variability, thereby furthering monsoon prediction capability;
  4. Design and implement a means to investigate scale interactions from sub-daily, through intraseasonal to interannual.
  5. Coordinate the formation and function of regional working groups and to advise WCRP on the development of mechanisms of support for meetings of the regional working groups
  6. Develop diagnostics for understanding of monsoon processes and assessment of model errors on a range of scales, and inform the need for new observations, both over land and ocean, to adequately gain this understanding and perform these assessments.
  7. Support a monitoring strategy designed by the Ocean Panels for the tropical and subtropical oceans necessary for investigating the structure and variability of the regional monsoons;
  8. Oversee development and implementation of plans for an optimised set of process studies in the Asian-Australian, American, and African monsoon regions;
  9. Coordinate and advise the Pan-WCRP numerical experimentation groups (WGSIP and WGCM, including its planning of CMIP6) on modelling priorities for advancing monsoon research;
  10. Promote interactions among atmospheric scientists, oceanographers and hydrologists and relevant others from interested nations in monsoon science activities;
  11. Work in cooperation with regional and multinational programs directed at improving our understanding of monsoon systems and at improving regional weather forecasts and seasonal climate predictions.
  12. Communicate existing products and their correct application and limitations to the impacts community and participate in relevant training activities.
  13. Report to the CLIVAR and GEWEX Scientific Steering Groups on an annual or more frequent basis, as appropriate.
