Atmospheric gravity waves have been a subject of intense research activity in recent years
because of their myriad effects and their major contributions to atmospheric circulation …

This paper provides a review of our current understanding of the processes responsible for
gravity wave saturation as well as the principal effects and variability of saturation in the …

More than 500 nightly mean temperature profiles have been obtained since 1981 by two
Rayleigh lidars located in south of France 550 km apart. In the mesosphere a temperature …

The Microwave Limb Sounder (MLS) on the Upper Atmosphere Research Satellite has now
produced the first global maps of small‐scale variances in the middle atmosphere. Initial …

A large data set obtained by Rayleigh lidars during 4 years has been analyzed in order to
describe the gravity wave climatology in the 30‐to 75‐km altitude range at mid‐latitude. The …

Using wind data monitored by the MU radar at Shigaraki, Japan (35° N, 136° E) in the three
years of 1986–1988, a statistical analysis is made of inertio-gravity waves (IGWs) with short …

We have regularly monitored mesospheric winds at 60–85km for three years with the MU
radar (35° N, 136° E), and have found that the variance of wind velocity fluctuations for …

Radial velocity and temperature data obtained at the MU Radar Observatory during October
and November 1986 are used to examine the character of the motion spectrum in the …

The nightly and seasonal variations in gravity wave activity in the mesopause region are
examined by analyzing 60 nights of Na lidar observations obtained during a 5‐year period …

We have observed wind motions from 60 to 90 km altitudes with the middle and upper
atmosphere (MU) radar during daylight hours (0800–1600 LT) from October 13 to 31, 1986 …
