Linear theory of the response of Na mixing ratio to gravity waves.

Studies the influence of gravity waves on the sodium layer by using a linear photochemical-dynamical coupling gravity wave model. Details of the model, which includes the background photochemistry and the photochemical reactions in the sodium layer; Calculation of amplitude and phase difference in the sodium mixing ratio to gravity waves; Indication that the lower part of the sodium layer is most sensitive to gravity waves; How temperature fluctuation is linked with in phase and out of phase conditions of the sodium mixing ratio.
