An anomalous non-convective high wind episode over Upper Michigan.
December 1, 2004... Abstract Several stations in northwestern Upper Michigan observed wind gusts over 40 kt behind a well-developed low pressure system during the evening and overnight hours of 6-7 April 1997. Observed data and gridded-model output show the...

Baseline climatology of sounding derived parameters associated with deep moist convection.
December 1, 2004... Abstract A baseline climatology of several parameters commonly used to forecast deep, moist convection is developed using an extensive sample of upper-air observations. Previous climatologies often contain a limited number of cases or do...

A wind-wave interaction explanation for Jelesnianski's open-ocean storm surge estimation using Hurricane Georges' (1998) measurements.
December 1, 2004... Abstract On 28 September 1998, Hurricane Georges made its final landfall near Biloxi, Mississippi with maximum one-minute sustained surface winds of 46 m[s.sup.-1] (90 kt) and a minimum central pressure of 960 hPa. The measured peak storm...

Structural characteristics of a particularly intense convectively driven high wind event.
December 1, 2004... Abstract West Texas Mesonet (WTM) observations and WSR-88D data are examined to ascertain the forcing mechanisms involved in the 30 May 2001 Lubbock, Texas, high-wind event. The wind event was characterized by a classic bow-echo signature...

Digital circumpolar vortex area index calculations for the Northern and Southern Hemispheres.
December 1, 2004... Abstract By calculating the area encompassed from the pole to the 5640-m contour at the 500-mb constant pressure level, the temporal ebb and flow of the cool air pool can be observed. Mean monthly, by year, circumpolar vortex area indexes...

Model-output post-processor algorithm development with interactive visualization software.
December 1, 2004... Abstract An "interactive" algorithm development methodology for creating meteorological forecast products is described. Using interactive grid manipulation software, gridded model forecast parameters are compared to either human forecasts,...

Partnership between the Greater New Orleans Expressway Commission and the National Weather Service Forecast Office in Slidell, Louisiana.
December 1, 2004... Abstract For the safety of life and property in southeast Louisiana in hazardous weather situations, a strong partnership has developed between the NOAA/National Weather Service Forecast Office in Slidell, Louisiana and the Greater New...

Effective use of various communication methods during a severe convective outbreak.
December 1, 2004... Abstract On the afternoon and evening of 15 May 2003, 26 tornadoes occurred across the Amarillo (AMA), NOAA/National Weather Service Forecast Office (WFO), County Warning Area (CWA), establishing a one-day tornado record for the 23 county...
