Ocean Circulation and Atlantic Decadal Variability
This month we look at work by Martha Buckley, David Ferreira, Jean-Michel Campin, Ross Tulloch and John Marshall, who have been using MITgcm to explore what role ocean circulation may play in Atlantic decadal variability. Asking the question: What is the role of the ocean circulation in Atlantic decadal SST variability, Buckley and co-workers use MITgcm to analyse the behavior of thermal anomalies within the framework of an idealised GCM.
Sea Ice
Work by Martin Losch of the Alfred-Wegener-Institute, Bremerhaven, Germany, Jean Michel Campin, Patrick Heimbach, Chris Hill (at MIT) and Dimitris Menemenlis (JPL) extending the reach of the MITgcm in to the Polar oceans, with the development of a dynamic-thermodynamic sea-ice model and its adjoint…
Adjoint Advances
Adjoint Advances story by Helen Hill Two MITgcm adjoint activities are (i) the development of an open-source, extensible automatic differentiation tool, OpenAD and (ii) the configuration of an ~18km resolution global ocean and sea-ice experiment as part of the ECCO2 project.
Sea-ice donuts
The MITgcm is now able to generate Sea-Ice Donuts.
