Breaking News: The MITgcm is now able to generate Sea-Ice Donuts. |
| 68 |
|
In a push to move forward MITgcm on the path of fundamental science and climate |
| 69 |
|
understanding, David Ferreira and Jean-Michel Campin |
| 70 |
|
simulated a Sea-ice Donut using a coupled AquaPlanet configuration (see |
| 71 |
|
movie <A href=movies/Sea_Ice_Donut_x1.mpg>here</A>). |
| 72 |
|
This experiment was initialized with the T and S fields from |
| 73 |
|
a previous Aquaplanet run which has polar sea-ice caps. These |
| 74 |
|
caps are associated with salt-compensated temperature inversions in the upper |
| 75 |
|
ocean. The new run is initialized without sea-ice and within a month, large |
| 76 |
|
sea-ice caps grow over the poles, rejecting salt. This triggers convection which |
| 77 |
|
in turns brings relatively warm water to the surface and melts the ice close |
| 78 |
|
to the poles. Here we have a <A href=movies/Sea_Ice_Donut_x1.mpg>donut</A>. |
| 79 |
|
Look out for that chapter on aqua-planets in the next IPCC report! |

News is back by popular request. New advection schemes are currently |
| 85 |
|
being tested. Some preliminary results from the new schemes can be seen |
| 86 |
|
<A href=news/advection_testing_jan07/advection_testing.html> |

here. |

The plots show a tracer being transported and stretched in the |
| 90 |
|
MITgcm advect_xz verification test. Both new schemes (OS7MP |
| 91 |
|
and Prather second-order scheme with limiting) have very low implied |
| 92 |
|
diffusivity. |
| 93 |
|
We are currently evaluating the |
| 94 |
|
schemes to assess their implied diffusivity, with a bottle of |
| 95 |
|
Jean-Michel's favorite Belgian |
| 96 |
|
beer going to the the least diffusive scheme - watch this space! |
