Refined data of systematic measurements of total water vapor in the atmosphere from May 1980 to April 2005 are presented. The data were obtained at the Issyk Kul atmospheric-monitoring station by the method of solar molecular-absorption spectroscopy. Over 25 years, the annual mean water-vapor content in the atmosphere increased by 4.5% at a mean rate of increase of 0.18% per year. However, the water-vapor content decreased in the last five years. The results of statistical processing of experimental data (general statistical characteristics, correlation coefficients, composite oscillations) are described. A refined model is proposed for forecasts of temporal variations in the monthly mean and annual mean water-vapor contents for the coming years. The model includes a linear trend and the sum of oscillations with periods close to the periods of a number of well-known geophysical phenomena. Regression equations are proposed to relate the water-vapor content in the atmospheric column to the surface temperature and absolute humidity. 相似文献

The paper discusses the conditions corresponding to the largest and smallest North Atlantic Oscillations (NAOs). It is shown
that in winter, when NAOs are at a minimum, the number of cyclones over the Black Sea increases. At the same time, cloudiness
in the Atlantic-European section becomes heavier, compared with the largest NAO. Heavy cloudiness over the Balkan and Karpaty
mountains, with NAO at a minimum, may imply the greater likelihood of Balkan cyclones’ penetration into the Black Sea region.
The mechanism responsible for the generation of maximum (minimum) cloudiness in the Atlantic-European section is discussed.

We describe one of possible mechanisms of the formation of anomalies of the cloud field over the North Atlantic and Europe
by using, as an example, the processes developed in the Atlantic-European sector during the natural synoptic season in the
spring of 1996. It is shown that the anomalies of the cloud field can be classified with the use of the index of the North
Atlantic oscillation and the latitude of the center of the Azorean maximum.

We have studied an electron-photon cascade in an isotropic photon field as one of the possible gamma-ray generation mechanisms in compact sources.A cascade in a monoenergetic photon field and in a field of the power-law spectrum is considered. Two types of interaction of cascade particles with the photon field are taken into account: the inverse Compton scattering of electrons and the photoproduction of electron-positron pairs by gamma-quanta. The cascade characteristics have been obtained by numerical solution of the kinetic equations. A quantitative and qualitative analysis is made of the main regularities of the cascade. We have established simple relations between the spectra of cascade particles and the parameters of the photon field and primary radiation. The magnetic field effect on the cascade characteristics is estimated. The results obtained are compared with the results of calculation of other investigators.In the first part of the paper we outline the method of solution and the results relating to the monoenergetic photon field. The theory of cascades in a photon field of the power-law spectrum and its application to the problem of gamma-rays in compact sources are discussed in the second part of the present paper. 相似文献

The results of investigations into the spatial variability of the Atlantic Ocean surface temperature field on interannual scales are presented. The analysis is based on monthly mean satellite data of the AVHRR Pathfinder Data JPL NOAA/NASA over 1985–2001. Specific features of the structure of the sea surface temperature (SST) fields averaged over 17 years, as well as fields of the gradient and variance of the SST time series, are described for each node of the data grid. It is shown with the use of the rhythmodynamic approach that spatial heat waves exist in the interannual variability of the SST field in two directions: zonal and meridional. 相似文献
