Ocean circulation models have evolved a lot in the past ten years.Recently, members from the CLIVAR Ocean Model Development Panel (OMDP) and collaborators summarized the new developments in ocean modeling since a similar OMDP review from 2010. Their review summarized the challenges and prospects at the forefront of present work in ocean modeling. This article can be found in Frontiers in Marine Science.
The El Niño-Southern Oscillation (ENSO) affects the rest of the world’s tropics by perturbing global atmosphere circulation, inducing anomalous Sea surface temperatures over the tropical Indian Ocean and Atlantic Ocean. The associated wind variations in the Indian Ocean and in the equatorial and north tropical Atlantic in turn contribute to ENSO dynamics. In addition, the tropical interbasin linkages vary on decadal time scales.
The scientific challenge is extreme due to the rich complexity of interactions and feedbacks between regional and global processes, each of which affects the global climate trajectory. Technical development, international coordination, and a close interaction between the science and stakeholder communities are also required.
The complicated communications between the BOB and the equatorial Indian Ocean through both ocean and atmospheric teleconnections are one of the most important aspects of the tropical Indian Ocean climate. By analyzing satellite observational data and ocean general circulation model experiments, this study investigates the key processes that determine the spatial distribution and seasonality of intraseasonal eddy kinetic energy (EKE) within the Bay of Bengal (BOB).
The Early Career Scientists Symposium was held alongside the 2016 CLIVAR Open Science Conference in Qingdao, hosted by the First Institute of Oceanography. The Symposium aimed to capture the ideas of early career researchers on pressing science priorities, immediate challenges, and emerging opportunities to help guide the future evolution of CLIVAR. 135 early career scientist (ECS) from 34 countries traveled to Qingdao and discussed their vision for the future of CLIVAR.
Under the 2015 Paris Agreement, nations agreed to limit global mean warming to 2°C, while also working toward the more ambitious goal of limiting warming to 1.5°C. However, current pledges to support the Paris Agreement would only limit global warming to 3°C. Would meeting the Paris temperature goals be sufficient to avoid an ice-free Arctic?
