++ 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 here). + 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 donut. + 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 + + here. + + 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 + technologies that have enabled this work and outlines the future goals of + this next generation planetary scale assimilation initiative. A pdf containing + the article can be found + + here. + ++ +

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 tqhe model output is now much easier to read and - understand.
