Welcome to the U.S. CLIVAR web site!

What is U.S. CLIVAR? CLIVAR (Climate Variability and Predictability) is an international, interdisciplinary research effort within the World Climate Research Programme (WCRP) focusing on the variability and predictability of the slowly varying components of the climate system. CLIVAR investigates the physical and dynamical processes in the climate system that occur on seasonal, interannual, decadal and centennial time-scales. CLIVAR recognizes that a critical measure of success in its research program is a transferal of insight and knowledge to routine production of climate forecasts, information and products. These forecasts and climate products have inherent value to decision makers.

U.S. CLIVAR has identified improved predictive capability as the main objective to leave as its legacy. The U.S. CLIVAR Committee steers the U.S. CLIVAR research enterprise along with three Panels to guide and implement the program in the broad functional goals of predictability/prediction; process and model improvement, and phenomena/observations/synthesis. The Panels develop and coordinate research plans and activities, provide input to agency programs, and assess achievement using measurable performance metrics (e.g. milestones).
