Probability of Encountering Thunderstorms at 50,000 and 60,000 Feet for Selected Routes Over the United States.
Abstract
The probability of encountering cumulonimbi has been determined for the worst route, month and time; that is, over the southern U.S. during July between 1600 and 1800 LST. Three transcontinental routes are examined: Miami to Los Angeles, Miami to San Francisco, and Washington D. C. to Los Angeles, distances measuring 2000, 2250, and 2030 nmi, respectively. Preliminary results indicated one encounter (within a 10-mile-wide flight path) for every 4 flights along the Miami-West Coast routes at 50,000 ft, and one for every 57 flights along the same routes at 60,000 ft. Clouds are assumed to be dome-shaped with base diameters ranging from 6.7 to 15 nmi at 50,000 ft and 6.7 to 10.5 nmi at 60,000 ft. (Author)
