On gamma radiation from the magellanic clouds and galactic supernova remnants — Possible antiproton sources in the galaxy     

V. L. Ginzburg  V. S. Ptuskin 《Journal of Astrophysics and Astronomy》1984,5(2):99-110

Radiation from the Magellanic Clouds is discussed from the point of view of near future possibilities in observational γ-ray astronomy. The γ-ray fluxes expected according to the metagalactic and galactic theories of the origin of cosmic rays are compared. It is shown that the strongest test of the metagalactic hypothesis will be provided by a determination of the ratio of γ-ray fluxes from SMC and LMC. The γ-ray luminosity of a typical young supernova remnant that can generate sufficient antiprotons is estimated. It is shown that such remnants must have a short phase during which they are very powerful γ-ray emitters.  相似文献   

The extremely late freezing of the European Russia’s rivers in the winter 2006–2007 and climate warming     

S. V. Borsch  B. M. Ginzburg 《Russian Meteorology and Hydrology》2009,34(6):392-397

In this paper, anomalies of freezing of the European Russia’s rivers in 2006–2007 are considered. Multiyear observation data are used for analysing of trends in time series, which express terms of the first floating ice appearance in the European territory of Russia. It is shown that, in the end of the 20th and beginning of 21st centuries, a tendency of later freezing of rivers in this territory was detected. Linear equations that describe temporal trends were obtained for various rivers. Three variants of terms of the first floating ice appearance until 2020 were computed in accordance with the basic climatic scenarios. It was shown that changes in the climatologic norms are significant for all the scenarios. In comparison with the present values, future changes in the norms can reach 5 through 15 days.  相似文献   

On the automatic interpretation of direct current resistivity soundings     

Ginzburg  Avihu  Loewenthal  Dan  Shoham  Yoram 《Pure and Applied Geophysics》1976,114(6):983-995

A method for the automatic inversion of resistivity soundings is presented. The procedure consists of two main stages. First, application of linear filters which transforms the apparent resistivity curve into the kernel function, and vice versa. In the second stage the first and second derivatives of the kernel function are calculated and used in a second-order modified Newton-Raphson iterative fitting procedure. The model obtained is optimal in the least squares sense. The method has been tried on some field examples and produced resistivity models which show a good agreement with the geological well logs.  相似文献

Some features of seasonal variations in the methane content in the atmosphere over northern Eurasia     

A. S. Ginzburg  A. A. Vinogradova  E. I. Fedorova 《Izvestiya Atmospheric and Oceanic Physics》2011,47(1):45-58

The climatic trends and basic features of seasonal variations in and anomalies of the concentration of methane in the atmospheric surface layer are considered on the basis of the current notion of the processes that form the global field of methane in the Earth’s atmosphere. Measurement data on the surface concentration of methane, which were obtained in Moscow and at a number of observation stations in Europe and Siberia in the fall-winter period of the first decade of the 21st century, have been analyzed. It is shown that, in the anomalously warm winter months of 2006/2007, the concentration of methane in the atmosphere over Moscow was higher than in the previous and following years. The excess concentration of methane amounted to 10% in March 2007, which is higher than the mean range of seasonal variations in the monthly mean concentration of surface methane. A comparison between the data obtained in Moscow and the data obtained at three stations of the NOAA global monitoring network and at three Russian Hydrometeorological Research Center stations shows the high spatial variability of the methane concentration in the atmosphere over northern Eurasia. The complex and multifactor processes that determine the content of methane in the atmospheric surface layer result in noticeable spatial and interannual deviations from the mean seasonal cycle of its concentration, which can manifest themselves on both regional and global scales. It is possible that the resumed increase in the content of methane in the Earth’s atmosphere recorded in 2007 (after its relative stabilization in the early 2000s) at the global monitoring network was also caused, to some extent, by the anomalously warm winter of 2006–2007 in northern Europe and western Siberia.  相似文献
