What NCEP data is used?

0

The sea level pressure, zonal and meridional wind at 1000, 850, and 200 hPa level data available on the hurricane portal are obtained from NCEP’s Global Forecast System analysis. The GFS analysis can be obtained from http://nomads.ncdc.noaa.gov. The GFS data archived on the hurricane portal are global (GFS product 003), have 1ºx1º spatial resolution and 4-times/day (6 hourly) temporal resolution. These data are available from NCEP beginning in February, 2004. A detailed description of the GFS model can be found on http://wwwt.emc.ncep.noaa.gov/gmb/moorthi/gam.html. A number of additional parameters from GFS will be available soon on the hurricane portal, including mass divergence profiles, potential temperature profiles, and vertical wind shear derived from the GFS products.
