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
Our CLIVAR members Prof. Fangli Qiao and Dr. Qi Shu, from SSG and NORP respectively, and former OMDP member Qiang Wang, contributed to the study of Marine Heatwaves (MHWs) and Total Heat
Exposures (THEs) in a future warming climate.
A member of the CLIVAR Tropical Basin Interaction Research Foci (TBI RF) recently published a paper that highlights the importance of coupled dynamics between the tropical Atlantic and Indian Oceans in shaping and intensifying super El Niño events. Their study, which utilizes a series of global climate model experiments, demonstrates that super El Niño events are driven by a complex interaction among the tropical Atlantic, Indian, and Pacific Oceans. It was observed that while individual effects were weaker and more uncertain, the combined effects were significantly stronger and more reliable. Specifically, the joint influence of the Atlantic and Indian Oceans was found to more effectively drive tropical Pacific warming. This process is linked to the nonlinear characteristics of convective sensitivity: when both oceans impact the Pacific simultaneously, they more effectively promote the eastward expansion of the Pacific warm pool, enhancing tropical Pacific convection and strengthening the Bjerknes feedback loop, ultimately leading to the formation of a super El Niño event.
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.
