Characteristics of Internal Inertial Gravity Waves and Inertial Waves in the Lower Stratosphere Observed by the MU Radar

Abstract: The MU radar observations were carried out for continuous five days each in September 1985 and1986 to reveal characteristics of internal gravity waves in the upper troposphere and lower stratosphere. Hodograph analysis and rotary spectral analyses in the vertical direction and time series of the data lead to the following results; (i) Upward propagating and saturating internal inertial gravity waves (IIGWs) are evidently observed through out all the observations in the lower region of the stratosphere lying ab… Show more

“…The final approach to the bottom agrees with observed, predominantly downward inertial wave energy propagation, close to the inertial latitude (Leaman & Sanford 1975;d'Asaro & Perkins 1984). Significantly, inertial oscillations have been observed in the stably stratified, lower stratosphere (Thompson 1978;Ushimara & Tanaka 1990;Hu & Holzworth 1997), while they are inconspicuous in the much weaker stratified troposphere (Holton 1979), in agreement with the fact that the homogeneous spherical shell lacks such a trap.…”

“…Their behaviour and fate is relevant to all rotating fluids occurring in nature or industry, particularly, as shown in the experiment here, when through mixing they affect the wave's medium. Examples include stars (Gough & McIntyre 1998), planetary atmospheres (Bjerknes et al 1933;Ushimara & Tanaka 1990), planetary cores (Aldridge & Lumb 1987;Olson & Aurnou 1999), oceans and lakes (LeBlond & Mysak 1978) and fluid-filled spinning spacecraft (Manasseh 1992).…”
