News is back by popular request. New advection schemes are currently |
| 59 |
|
being tested. Some preliminary results from the new schemes can be seen |
| 60 |
|
<A href=news/advection_testing_jan07/advection_testing.html> |

here. |

The plots show a tracer being transported and stretched in the |
| 64 |
|
MITgcm advect_xz verification test. Both new schemes (OS7MP |
| 65 |
|
and Prather second-order scheme with limiting) have very low implied |
| 66 |
|
diffusivity. |
| 67 |
|
We are currently evaluating the |
| 68 |
|
schemes to assess their implied diffusivity, with a bottle of |
| 69 |
|
Jean-Michel's favorite Belgian |
| 70 |
|
beer going to the the least diffusive scheme - watch this space! |

A short article entitled |
| 76 |
|
"NASA Supercomputer Improves Prospects for Ocean Climate Research" |
| 77 |
|
in the current EOS (volume 86, number 9, March 1 2005) |
| 78 |
|
gives a succinct overview of some of the advanced high-resolution |
| 79 |
|
state-estimation work being undertaken with MITgcm by members |
| 80 |
|
of the ECCO consortium. The article describes |
| 81 |
|
ground-breaking computational |
| 82 |
|
technologies that have enabled this work and outlines the future goals of |
| 83 |
|
this next generation planetary scale assimilation initiative. A pdf containing |
