Upper level wind analysis from GOES water vapor winds

from

NOAA/NSSL and UW-Madison/CIMSS


Mesoscale analyses of upper level winds derived from GOES water vapor imagery are presented here for use by the IHOP field campaign over the south central US during the spring of 2002.  These winds are from the  CIMSS  water vapor wind tracking algorithm applied to GOES-8 data on an experimental basis at 30-minute intervals in near-real time.  It should be noted that the amount of wind editing has been reduced, as compared to other implementations of the algorithm, in order to include larger deviations from the model 'guess' fields.  This allows the detection of perturbated flow aloft due to convection and other mesoscale features not correctly captured by models.

The products shown here are focused on the IHOP domain in Oklahoma and Kansas.  These and additional products are available over much of the U.S. CONUS from the  GOES-8 Satellite Winds Page .  This page should be used in order to view the larger scale wind field surrounding the IHOP domain.  Additional products available over this larger domain include comparisons of analyzed fields with a global (NOGAPS) and mesoscale (RUC-2) model.  Also, an archive of interactive loops and wind data files is available from that page or by clicking here.

Analyses available from the selections below include background water vapor imagery with user selectable overlays of:

1. Wind vectors and associated mid-layer pressure levels

2. Objectively analyzed fields at 300 hPa:

The objective analysis is based on available wind vectors and a background field from a global forecast model (NOGAPS) References:
