Abstract: Four types of chinook winds are described and features detectable in satellite pictures are shown. The hypothesis that large amplitude lee waves could be a possible driving mechanism for chinook winds is investigated for ...

Abstract: The occurrence of extreme low-level wind shear at 10 stations in the conterminous United States is investigated by applying a bivariate frequency-distribution analysis to rawinsonde and pibal data. Data for Denver, Colo., ...

Abstract: Inversions at Point Arguello, California, as detected in 4½ years by rawinsondes at 0400 and 1600 PST, are related to surface wind direction and speed and surface temperatures. Nocturnal inversions based below 1000 ft msl ...

Abstract: A Monte Carlo technique simulates the effects of cloudcover on the performance of the Apollo On-board Navigation System. For each of three simulated Apollo missions, the probability of sighting at least a specific number ...
