Wind Blown

In a new study, researchers from Scripps have been using MITgcm to evaluate the role form stress across bottom topography plays in balancing the input of stress by wind at the surface.


Slip Sliding Away…

Looping the loop in the Gulf of Mexico

alt text goes hereThis month we focus on several recent papers that have used MITgcm and its adjoint to perform state estimates and explore its ocean forecasting capabilities in the Gulf of Mexico.


Overflowing with Movies

Nuno Serra from the University of Hamburg has used MITgcm in many ocean modeling projects, both from a process-modelling perspective and “realistically”, incorporating forcing from NCEP and ECMWF. He is especially interested in the processes regulating North Atlantic and North Pacific inter-annual to inter-decadal variability. A particular passion is overflows.


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 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.


Adjoint approaches to assessing local vulnerability to buoyant surface plumes

Spreading of a buoyant surface plume modeled using MITgcmPrompted by the recent spill in the Gulf of Mexico, Ross Tulloch, Chris Hill and Oliver Jahn have been using MITgcm to compute the vulnerability of individual locations to remote buoyant surface plumes.


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…


OCCA

Surface height anomaly from OCCAThis month we focus on work by Gael Forget and the ECCO team who have been using MITgcm to construct a new ocean atlas. By using MITgcm as a means of optimally synthesising data within the framework of a physically accurate general circulation model, OCCA (short for OCean Comprehensible Atlas) provides a singularly accurate 3-year “snap-shot” of the global ocean state for the period December 2003 to November 2006…
