Ml. Bentley et Sr. Cooper, THE 8 AND 9 JULY 1993 NEBRASKA DERECHO - AN OBSERVATIONAL STUDY AND COMPARISON TO THE CLIMATOLOGY OF RELATED MESOSCALE CONVECTIVE SYSTEMS, Weather and forecasting, 12(3), 1997, pp. 678-688
This study addresses a particularly damaging derecho that occurred on
8 and 9 July 1993. This progressive, warm season derecho organized in
northeastern Colorado and swept through Nebraska and Kansas before dis
sipating in western Iowa, Records indicate this was one of the costlie
st single storms in Nebraska's history. A detailed analysis was conduc
ted to determine which synoptic and mesoscale processes initiated, sus
tained, and dissipated the derecho. Research has provided insights int
o derecho environments and structure; however, observational studies u
sing comprehensive datasets are necessary for comparative examinations
. This study presents several unique characteristics of the derecho-pr
oducing mesoscale convective system, including multiscale interactions
and observational data with strong temporal relevance to the event. I
t is both the climatological and unique characteristics that are exami
ned in this investigation.
