dc.description.abstract | A control and 4 deg equatorward SH westerly wind shift (PTB) experiments are performed with the MOM5-SIS-WOMBAT (1/4 degree horizontal resolution) model. The impact of the 4 deg equatorward SH westerly wind shift on the oceanic circulation and ocean biogeochemistry is investigated. Methods and results are described in Gray W., de Lavergne C., Wills, R.C.J., Menviel, L., Spence, P., Holzer M., Kageyama, M., Michel, E., Poleward shift in the Southern Hemisphere westerly winds synchronous with the deglacial rise in CO2, 2021, In review | |

dcterms.accrualMethod | A control and 4 deg equatorward SH westerly wind shift (PTB) experiments are performed with the MOM5-SIS-WOMBAT (1/4 degree horizontal resolution) model. MOM5-SIS-WOMBAT has a Mercator horizontal resolution of 0.25° (~11 km grid spacing at 65°S), and 50 vertical levels (Hogg et al., 2017, Menviel et al., 2018). The model is initialised with modern-day temperature and salinity distributions, and biophysical fields derived from an observation-based climatology (GLODAP v2, 2016). The model is then spun-up for 700 years with version 2 of the Coordinated Ocean-ice Reference Experiments (CORE) Normal Year Forcing (NYF) reanalysis data, representative of a ‘normal year’ during the recent instrumental period. A 4° equatorward shift (with no change in magnitude) is applied to the near surface wind speeds between 25°S and 70°S in the PTB experiment. The experiment is run for 125 years. | |

unsw.relation.projectDesc | THE OCEANIC CIRCULATION VARIED SIGNIFICANTLY OVER THE LAST GLACIAL CYCLE (~140,000 YEARS) AND IS EXPECTED TO CHANGE OVER THE COMING CENTURIES DUE TO RISING ATMOSPHERIC CO2. THIS PROJECT AIMS TO UNDERSTAND THE IMPACT OF CHANGES IN OCEAN CIRCULATION ON MARINE BIOGEOCHEMISTRY, CLIMATE AND ULTIMATELY THE ANTARCTIC ICE-SHEET BY COMBINING TRANSIENT SIMULATIONS OF THE LAST GLACIAL CYCLE PERFORMED WITH AN EARTH SYSTEM MODEL WITH COMPILATION OF PALEOPROXY RECORDS. THE IMPACT OF FUTURE CHANGES IN OCEANIC CIRCULATION ON OCEAN ACIDIFICATION AND OXYGEN CONTENT WILL BE FURTHER ASSESSED WITH A STATE-OF-THE-ART HIGH-RESOLUTION OCEAN, CARBON CYCLE MODEL. THIS PROJECT WILL LEAD TO IMPROVED UNDERSTANDING OF PROCESSES AND FEEDBACKS WITHIN THE EARTH SYSTEM. | |
