Abstract: The general features of atmospheric acoustic structure in the lower mesosphere have been known for several decades. Initial studies were accomplished by surface observations of anomalous propagation of pressure perturbations ...

Abstract: Data obtained from the Meteorological Rocket Network indicate gross stratospheric circulation responses to solar heat input which range as high as forty days late in the case of the reversal from winter westerly to summer ...

Abstract: The intimate relationship between the local speed of sound of a flight environment and the lift and/or drag on a vehicle is discussed. The fact that this parameter will become increasingly significant as the speed increases ...

Abstract: Rotation of the earth introduces a diurnal perturbation into the heating experienced by the ozonosphere through absorption of solar ultraviolet radiant energy. This diurnal heat wave induces perturbations in the stratospheric ...

Abstract: Measurements of droplet count have been made in fogs, natural clouds, and laboratory clouds. All droplets larger than 0.75-micron radius that were contained in a small volume (approximately 1 cubic centimeter) of the cloud ...

Abstract: Samples of more than 35 natural clouds were passed through a special centrifuge and an ion filter in such a way that the free electricity on the droplets and on the air could be measured separately. The net charge on typical ...

Abstract: The performance of the Loki wind-sensing rocket system is discussed. Altitudes in excess of those obtainable by standard sounding-balloon techniques were sampled in a series of ten Phase I Loki rockets fired at White Sands ...
