Paper Abstract

The data of long-term (1980 - 2000) continuous spectroscopic measurements of total water vapor content in the column of the continental atmosphere (the Issyk Kul station, the center of Eurasia) are given. The amplitudes and phases of water vapor seasonal variations have been defined, their long-term values and seasonal differences of the gas content variability are given for the observation site depending on the atmospheric temperature. A year-to-year variability of atmospheric total water vapor content is stated under a linear approximation that corresponds to an annual increase of its content by 0.015 g./cm2. With the help of the spectral analysis of the data the main periodic components of water vapor variability were revealed with the periods of 6, 12, 35, 51 and 110 months. Their connection is shown with the temperature seasonal variations (periods of 6 and 12 months), with the El Nino phenomenon global consequences (a 51 month period) and with powerful volcanic eruptions (periods of 35, 51 and 110 months). An empirical statistical model was constructed for the atmospheric water vapor variability, that describes its mean monthly contents with an error of +/- 13%.
