Processing of the US climatologies continued on schedule. These included large sector composites for March, April and May 1999 and wind regime composites for February, March and April 1999. Combined monthly products covering 1998 and 1999 were processed for January, February, and March for GOES channels 1 and 4.

Collection of PCGRIDDS - ETA 12 UTC model data continues.  The gridded data  are being used to generate a mean boundary layer (~1000-700 mb) wind speed and a resultant boundary layer wind direction to designate a wind regime for specific AWIPS sites for use in the  monthly satellite CONUS climatologies.  Wind regimes have been determined for February, March, and April 1999.

Full disk water vapor imagery (three hour interval) from GOES-8 has been used to calculate 5-day running averages on pixels warmer than -35 C.  The imagery from July-September 1996, July-November 1997 and June through November 1998 are being examined over the Atlantic basin for trends in dry/moist  periods and their relations to hurricane formation.
