CLIVAR is a Core Project of the World Climate Research Programme (WCRP) dedicated to understanding the role of the ocean in the variability, predictability and change of climate and to the benefit of society and the environment in which we live. The International CLIVAR Project Office (ICPO) serves as the executive arm of the CLIVAR Scientific Steering Group and its panel and working groups. The ICPO is based at the Ocean University of China (OUC), Qingdao, China. The OUC and WCRP invite applications for the position of ICPO Staff Scientist.




This second-generation CLIVAR Science Plan builds on the important legacy of CLIVAR emerging since its inception in 1992 and redirects the CLIVAR goals and priorities for the coming decade after consultation with scientists and stakeholders throughout the climate community.

Science Highlights

Please have a look at the Guidelines for Science Highlights

The Tropical Pacific Decadal Variability (TPDV) Working Group of the CLIVAR Pacific Region Panel recently published a review paper that evaluates our understanding of the mechanisms behind TPDV.  No final consensus exists on the relative importance and efficacy of the mechanisms, but the tropical ocean adjustment to varying wind forcing likely plays a key role in the origin of decadal timescales.  These processes are elucidated in this review paper which is a product of rigorous discussions at several virtual meetings over the span of two years since the working group’s establishment in May 2021. 

Researchers from the Ocean and Atmosphere Studies Laboratory (LOA), National Institute for Space Research (INPE) and collaborators, published  the article “Oceanic SACZ produces an abnormally wet 2021/2022 rainy season in South America”, in Scientific Reports.

Marine heatwaves (MHWs) are events characterized by prolonged and extremely warm ocean conditions, and have been detected in recent decades over many regions of the global ocean. Some recent studies led by D. Mawren and with the contribution from J. Hermes (co-chair of IORP), provide an improved understanding of the important role of horizontal advection, associated with anticyclonic eddies on the evolution of MHWs, as well as the co-occurring extremes in the Mozambique Channel.
