Abstract

A series of radiosonde flights over Laverton, Victoria (38ยฐS), is found to have sufficient vertical (100m) and temporal (3 h) resolution, and sufficient length (28 days) to detect inertial waves. Fourier analysis shows that in the stratosphere there is a strong anticyclonic rotation of the wind vector which has energy concentrated near the local inertial frequency. This rotation is associated with a vertical wavelength between 1 and 3 km, and a downward phase propagation. There is no sign of inertial waves in the troposphere. The waves appear to be generated below the stratosphere and spread upwards.

## Abstract During a routine instrumentation flight check in the lower stratosphere periodic variations of temperature and winds were observed. It is deduced that these variations are gravity waves which appear to be associated with a narrow frontal zone separating regions with different potential
