Operating safely in adverse weather environmentsNASA has undertaken three research programs since 1974 that are concerned with the gathering of flight data under adverse and potentially severe weather conditions, such as wind shear, wind turbulence, icing, hail, rain, and lightning. All six conditions may be present in a given storm formation. Attention is presently given to the B-57B, DHC-6, and F-106B research aircraft employed by these flight data gathering efforts, and the accumulated experience with prediction, remote sensing and weather system penetration methods is discussed. Research results are compared with airliner data for 1970-1975. Evidence is found for two electrically active charge centers in thunderstorms, one of which lies at altitudes whose temperature is near the freezing level, and another at higher altitudes, in the temperature range from -25 to -35 C.
