Abstract
Routine Navy-sponsored 300-mb. transosonde flights from Japan for the months September 1957–February 1958 are analyzed. Statistics on the wind velocity, acceleration, and power spectra for the flights are indicated. With the aid of radiosonde data, the mean vertical motions and mean horizontal divergences along the flights are evaluated. Comparisons of transosonde velocities with geostrophic velocities obtained from National Weather Analysis Center maps are presented.
