Breaking News: The MITgcm is now able to generate Sea-Ice Donuts. |
67 |
|
In a push to move forward MITgcm on the path of fundamental science and climate |
68 |
|
understanding, David Ferreira and Jean-Michel Campin |
69 |
|
simulated a Sea-ice Donut using a coupled AquaPlanet configuration (see |
70 |
|
movie <A href=movies/Sea_Ice_Donut_x1.mpg>here</A>). |
71 |
|
This experiment was initialized with the T and S fields from |
72 |
|
a previous Aquaplanet run which has polar sea-ice caps. These |
73 |
|
caps are associated with salt-compensated temperature inversions in the upper |
74 |
|
ocean. The new run is initialized without sea-ice and within a month, large |
75 |
|
sea-ice caps grow over the poles, rejecting salt. This triggers convection which |
76 |
|
in turns brings relatively warm water to the surface and melts the ice close |
77 |
|
to the poles. Here we have a <A href=movies/Sea_Ice_Donut_x1.mpg>donut</A>. |
78 |
|
Look out for that chapter on aqua-planets in the next IPCC report! |

News is back by popular request. New advection schemes are currently |
84 |
|
being tested. Some preliminary results from the new schemes can be seen |

here. |

The plots show a tracer being transported and stretched in the |
89 |
|
MITgcm advect_xz verification test. Both new schemes (OS7MP |
90 |
|
and Prather second-order scheme with limiting) have very low implied |
91 |
|
diffusivity. |
92 |
|
We are currently evaluating the |
93 |
|
schemes to assess their implied diffusivity, with a bottle of |
94 |
|
Jean-Michel's favorite Belgian |
95 |
|
beer going to the the least diffusive scheme - watch this space! |

A short article entitled |
101 |
|
"NASA Supercomputer Improves Prospects for Ocean Climate Research" |
102 |
|
in the current EOS (volume 86, number 9, March 1 2005) |
103 |
|
gives a succinct overview of some of the advanced high-resolution |
104 |
|
state-estimation work being undertaken with MITgcm by members |
105 |
|
of the ECCO consortium. The article describes |
106 |
|
ground-breaking computational |
107 |
|
technologies that have enabled this work and outlines the future goals of |
108 |
|
this next generation planetary scale assimilation initiative. A pdf containing |
109 |
