内容記述 | This paper describes some computational results on the mesospheric sodium layer using the newly measured chemical reaction rate coefficients. After the most updated neutral chemistry, the calculated winter/summer ratio is consistent with the observational results. The time constant of sodium atoms is found to be shorter than 20s (70-90km). This short time constant invalidates a previous model of sodium gravity waves, which assumes that sodiums are chemically conservative during their vertical moving induced by gravity waves. We proposed a new mechanism here to explain the wavelike structures of the sodium layer drived by gravity waves. | |||||||||
