Thunderstorm Gust Fonts--Observations and Modeling.

reportActive / Technical Report | Accession Number: ADA068425 | Open PDF

Abstract:

Gust front structures as observed and as modeled are reviewed and a mean model presented. Integrated observations from the 461 m meteorologically instrumented tower at Oklahoma City, OK, aircraft, weather satellites and Doppler radar are compared to one and two-dimensional models to provide a better understanding of the gust front. In the mean, updrafts of 3 msec accompany the gust fronts approach. Horizontal wind shears are 8 msec per km. Gust front cases in 1976 and 1977 are presented along with a data log of tower observations. Aircraft observations during gust front flights are also presented. Author
