Stratospheric Mountain Wave Forecasts for West Coast USA


Stratospheric Forecasts: Western USA (stopped 26 February 2004)
26 February 2004: NRL has terminated all funding for the MWFM 6.2 research and validation project. Consequently, due to staff cuts we are no longer able to provide operational twice-daily troposphere-stratosphere mountain wave forecasts for the sectors indicated below or to continue validation work with associated colleagues at various centers. We will continue to provide forecasts on a campaign basis for contract customers, such as NASA scientists involved in this summer's MidCiX campaign. We will also continue our R&D efforts at a reduced level focusing more on science and related issues.

All Forecasts are valid at 12:00 UT on the day in question
The NCEP GFS forecast job runs at ~03:20 EST and 05:20 EST each day.
The NOGAPS forecast job runs twice daily runs at ~08:00 EST and ~20:00 EST, utilizing the NOGAPS 0Z and 12Z forecast update cycles, respectively. You can keep track of today's MWFM-NOGAPS forecast runs by checking the new logfile.

100-70 hPa corresponds roughly to the flight altitude interval FL530-FL600.
