An analysis is presented of the data obtained from an instrumented balloon rising through a jet stream. Emphasis is placed on the determination of the vertical atmospheric velocity. The analysis of the temperature and velocity perturbations shows evidence of a wave structure propagating upward. An estimation of the vertical flux of horizontal momentum is given. These preliminary results show clearly the ability of our helisonde to measure wave motions with a vertical velocity as low as 0.1 m s-1. The method allows a direct measurement of wave propagation in the stratosphere.DOI: 10.1111/j.1600-0870.1984.tb00263.x
