200 highly accurate balloon soundings taken at 44(DEGREES)N, 1(DEGREES)W in the Southwest region of France are analysed, using the multiple filtering technique of (Dziewonski et al. 1969). / Inertio-gravity waves having periods between 6 and 17 hours, horizontal wavelengths between 800 and 1250 km and vertical wavelengths between 1200 and 1600 m are isolated from the data. A stability analysis shows that these waves are generated in the Troposphere by a mixed inertia-shear instability and propagate upwards in the Stratosphere. Evidence is presented to prove the existence of inertial waves in the atmosphere as well as the mechanism by which they are generated. / Results obtained from the data are compared to the theory and a fair agreement is found. It is also shown that flux divergence of heat and momentum within this lower range of the inertio-gravity wave spectrum is not capable of transporting momentum upwards into the Mesosphere to bring about the kind of temperature gradient and wind reversals in the context of the Holton-Matsuno theory. / The wave spectrum is found to follow a -5/3 inertial subrange slope with an energy cascade towards high wavenumbers. The universal constant (,(PROPORTIONAL)) is found to lie betwen 1.5 and 11, supporting some findings by (Lilly, 1983) who found a value of 9.8. / Source: Dissertation Abstracts International, Volume: 45-11, Section: B, page: 3534. / Thesis (Ph.D.)--The Florida State University, 1984.
