Tracking Down Climate’s Tipping Points

A group at UNIGE in Switzerland uses MITgcm aquaplanet experiments to probe climate sensitivity.

Breaking the Ice

Researchers from Germany and Canada study fracturing of sea ice by comparing different rheologies in the MITgcm sea-ice package


This month we spotlight work seeking to couple the MITgcm with another open-source marine biogeochemistry tool developed and maintained by a consortium involving modelers across Europe and also South Africa.

Snowballs in Summer

Cool off with a study from Ashkenazy, Gildor, Losch and Tziperman who use MITgcm to explore the ocean in models of snowball earth.

Sea – Ice Interplay

In a novel approach, MITgcmers Ian Fenty and Patrick Heimbach use optimal state and parameter estimation to improve the sea-ice simulations.

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.

Arctic Carbon Cycle Modeling

Arctic Biogeochemical Model - Change in Surface Net Community Production, year-on-year between 2006 and 2007 using MITgcm. 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.

Modeling the Ocean Response to Hurricanes

Hurricane IsabelFamiliar as we are with satellite images of hurricanes, the impact of these powerful storms on the upper ocean is markedly less visible. Dr Sarah Zedler (Texas A&M University) has been using MITgcm to help understand the features that appear in oceanic field data as a result of hurricane passage above.

Climate Determinism Revisited

Stable states schematic 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…

Modeling Nordic Seas

Modeling the Denmark Strait circulation using MITgcmThis month we look at work by Tom Haine, Professor of Physical Oceanography at Johns Hopkins University who is using MITgcm to model high-frequency fluctuations in the flow through the Denmark Strait…
