Latest WRF v3.2 run: Outflow

 

13 July 2010: New run still has outflow jet issues.
After running for a month in model time, the outflow, here shown as 200 hPa tangential wind speed (warm colors are cyclonic), shows signs of feeling the effects of the period boundaries of the outermost domain (27 km resolution). The outflow falls apart, and is soon followed by the dissipation of the hurricane at the surface.
We are trying to rememdy this problem by adding a much larger, coarser (81 km) resolution fourth domain onto the outside so that the outflow won't interact with the boundaries. This once again bothered the adaptive timestep bug, but after fits and starts and lots of crashes it is finally running so we will see soon if this fixes the problem.
