THUNDERSTORM GUST FRONTS--OBSERVATIONS AND MODELING

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 m/sec accompany the gust front's approach. Horizontal wind shears are 8 m/sec 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)
