Strange New Worlds
This month we focus on research using MITgcm to model atmospheres on Jupiter-like exoplanets showcasing work by recent University of Arizona, Lunar and Planetary Laboratory graduate, Nikole Lewis.
MITgcm on Ice
In a recent paper in the Journal of Physical Oceanography, An Nguyen (MIT) and co-authors Ronald Kwok (JPL) and Dimitris Menemenlis (JPL) report on work using MITgcm to better understand the origin and character of the western arctic, upper halocline.
Modeling the Gulf of Aqaba (Gulf of Eilat)
Long-time MITgcm-ers Eli Biton and Hezi Gildor have been using the model to explore the circulation in the Gulf of Aqaba (Gulf of Eilat), a terminal elongated basin that exchanges water with the northern Red Sea
Wind Stress and Southern Ocean Meridional Overturning
Ryan Abernathey and co-workers have been using idealised MITgcm simulations to explore the dependence of Southern Ocean meridional overturning on wind stress.
A Slippery Problem
Deremble and co-authors have been using MITgcm to revisit the problem of no-slip boundary conditions in ocean models.
Modeling Nordic Seas II
Mike Spall, a Senior Scientist in the Physical Oceanography Group at the Woods Hole Oceanographic Institution, has been using MITgcm to understand newly observed characteristics of the Denmark Strait Overflow.
Baroclinic Instability in the Ocean
In a new JPO paper, Ross Tulloch, John Marshall, Chris Hill and Shafer Smith report on an observational, modeling and theoretical study of the scales, growth rates and spectral fluxes of baroclinic instability in the ocean, permitting a discussion of the relation between the instability scale, the first baroclinic deformation scale (R1) and the equilibrated eddy scale.
Arctic Carbon Cycle Modeling
Motivated by observations indicating rapidly falling annual sea-ice minima, Manfredi Manizza and co-workers have been using an Arctic configuration of MITgcm to explore the Arctic Ocean Carbon Cycle.
Climate Determinism Revisited
In a first for models simulating the 3d dynamics of both ocean and atmosphere, the MITgcm climate model has been found to exhibit three different stable states for exactly the same set of parameters and external forcings, suggesting that climates may exhibit multiple equilibria even in the presence of a vigorous internal variability sustained by weather systems and ocean-atmosphere-sea ice interactions…
