The Barents Sea Opening: shifting from a freshwater sink to source for the Arctic Ocean

Recently, together with colleagues, two members from CLIVAR Ocean Model Development Panel (OMDP) conducted a comprehensive analysis on the Arctic sea surface salinity (SSS), liquid freshwater content (LFWC) and freshwater budget by comparing the CMIP6 to the CMIP5 results, showing that the salinity of the Barents Sea Opening is projected to keep declining in the future.

Impact of extratropical thermal forcing in the simulation of tropical Atlantic-Pacific basin interactions

A recent paper on this subject by researchers at the University Complutense of Madrid examines the role of tropical convection, specially the location of the Inter Tropical Convergence Zone (ITCZ), in the occurrence of the two main tropical Atlantic-to-tropical Pacific basin interactions: the equatorial Atlantic to equatorial Pacific teleconnection, and the North Tropical Atlantic to equatorial Pacific teleconnection.

Polar warming and ice free conditions under Paris Agreement thresholds as simulated by CMIP5 and CMIP6 models

Aiming to account for the Polar Amplification, this study used global climate simulations from CMIP5 and CMIP6 to investigate the effects of three different global warming thresholds (1.5 °C, 2 °C and 3 °C) and the projected ice free occurrence of both poles.

Sea surface cooling mechanisms caused by oceanic SACZ episodes at Southwestern Atlantic

A recent study led by Dr Luciano Pezzi, member of the CLIVAR/CliC/SCAR Southern Ocean Region Panel, was published in Climate Dynamics. This work brings a new approach to the study and understanding of the oceanic surface cooling that the oceanic South Atlantic Convergence Zone (SACZ) causes, concerning air-sea interaction processes. 

Another Record: Ocean Warming Continues through 2021 despite La Niña Conditions

A recent study published in Advances in Atmospheric Sciences (https://doi.org/10.1007/s00376-022-1461-3), led by Dr. Lijing Cheng, member of CLIVAR GSOP, provides the first analysis of recent OHC changes through 2021 from two international groups, i.e. IAP/CAS in China and NCEI/NOAA in the US.

A Decade of Eastern Tropical Indian Ocean Observation Network (TIOON)

A recent study in Bulletin of American Meteorological Society (BAMS) led by CLIVAR IORP member - Dr. Dongxiao Wang’s team (Zeng et al., 2021) briefly overviews the decadal progress of the eastern Tropical Indian Ocean Observing Network (TIOON), a persistent observation effort implemented by China.

Changing El Niño–Southern Oscillation in a warming climate

A recent synthesis in Nature Review Earth and Environment led by the CLIVAR community and in particular the CLIVAR Pacific Region Panel (Cai et al., 2021, https://doi.org/10.1038/s43017-021-00199-z) assesses the potential future changes of multiple aspects of ENSO and the underlying processes behind such changes.
