Breaking News: The MITgcm is now able to generate Sea-Ice Donuts. |
|
|
In a push to move forward MITgcm on the path of fundamental science and climate |
|
|
understanding, David Ferreira and Jean-Michel Campin |
|
|
simulated a Sea-ice Donut using a coupled AquaPlanet configuration (see |
|
|
movie <A href=movies/Sea_Ice_Donut_x1.mpg>here</A>). |
|
|
This experiment was initialized with the T and S fields from |
|
|
a previous Aquaplanet run which has polar sea-ice caps. These |
|
|
caps are associated with salt-compensated temperature inversions in the upper |
|
|
ocean. The new run is initialized without sea-ice and within a month, large |
|
|
sea-ice caps grow over the poles, rejecting salt. This triggers convection which |
|
|
in turns brings relatively warm water to the surface and melts the ice close |
|
|
to the poles. Here we have a <A href=movies/Sea_Ice_Donut_x1.mpg>donut</A>. |
|
|
Look out for that chapter on aqua-planets in the next IPCC report! |

News is back by popular request. New advection schemes are currently |
|
|
being tested. Some preliminary results from the new schemes can be seen |

The plots show a tracer being transported and stretched in the |
|
|
MITgcm advect_xz verification test. Both new schemes (OS7MP |
|
|
and Prather second-order scheme with limiting) have very low implied |
|
|
diffusivity. |
|
|
We are currently evaluating the |
|
|
schemes to assess their implied diffusivity, with a bottle of |
|
|
Jean-Michel's favorite Belgian |
|
|
beer going to the the least diffusive scheme - watch this space! |

A short article entitled |

|
"NASA Supercomputer Improves Prospects for Ocean Climate Research" |
|
|
in the current EOS (volume 86, number 9, March 1 2005) |
|
|
gives a succinct overview of some of the advanced high-resolution |
|
|
state-estimation work being undertaken with MITgcm by members |
|
|
of the ECCO consortium. The article describes |
|

ground-breaking computational |

this next generation planetary scale assimilation initiative. A pdf containing |

MITgcm is now able to write and (to a lesser extent) read NetCDF files. |
|
|
The framework (the "MNC" package) has been tested by numerous developers |
|
|
on literally dozens of machines and, for the past month, has been a |
|
|
working part of our standard verification suite. We encourage MITgcm |
|
|
users (especially new users) to try out the MNC package since the model |
|
|
output is now much easier to read and understand. For further NetCDF |

A new movie by Dimitris Menemenlis and Chris Henze shows ice dynamics |

over the North Pole. The viscous-plastic behavior of ice sheets subject |

to wind forcing and ocean currents can be clearly seen in the |
|
|
translucent ice-sheet. The movie can be downloaded from <a |

A spectacular movie by Chris Henze of NASA AMES beautifully captures an |

eddy permitting expanded cube sphere MITgcm simulation being carried out, |
|
|
as part of the <a href="http://www.ecco-group.org">ECCO</a> project, by |
|
|
Dimitris Menemenlis and others at JPL with help from core MITgcm team members |
|
|
and staff from NASA AMES. The animation |
|
|
shows the speed of ocean currents at 15m depth from the simulation, it can be |
|
|
downloaded <a href=news/cube_6.mpg>here</a> (its 47MB |
|
|
but worth waiting for!). A second animation with different perspectives and |
|

rotation can be downloaded <a href=news/cube_7.mpg>here</a>. |

As described <a href=news/agu_2004/menemenlis_et_al.pdf>here</a> Dimitris Menemenlis |

will be presenting aspects of this calculation at AGU in Portland. |
