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   

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

Peculiarities of the outer radiation belt dynamics during the strong magnetic storm of May 15, 2005     

L. V. Tverskaya  E. A. Ginzburg  T. A. Ivanova  N. N. Pavlov  P. M. Svidsky 《Geomagnetism and Aeronomy》2007,47(6):696-703

The dynamics of energetic electrons (E _e =0.17–8 MeV) and protons (E _p =1 MeV) of the outer radiation belt during the magnetic storm of May 15, 2005, at high (GOES-10 and LANL-84 geosynchronous satellites) and low (Meteor-3M polar satellite) altitudes is analyzed. The data have been compared to the density, plasma velocity, solar wind, and magnetic field measurements on the ACE satellite and geomagnetic disturbances. During the magnetic storm main phase, the nighttime boundary of the region of trapped radiation and the center of westward electrojet shifted to L ～ 3. Enhancements of only low-energy electrons were observed on May 15, 2005. The belt of relativistic electrons with a maximum at L ～ 4 was formed during the substorm, the amplitude of which reached its maximum at ～0630 UT on May 16. The results are in good agreement with the regularity relating the position of a maximum of the new relativistic electron belt, boundaries of the trapped radiation region, and extreme low-latitude position of westward electrojet center to the Dst variation amplitude.  相似文献   

Dynamics of radiation belt relativistic electrons in November 2004–January 2005     

L. V. Tverskaya  N. N. Veden’kin  E. A. Ginzburg  T. A. Ivanova  N. N. Pavlov  P. M. Svidskii 《Geomagnetism and Aeronomy》2006,46(2):146-150

The radiation belt dynamics during the extreme solar events in November 2004 and January 2005 is studied based on the measurements of relativistic electrons (with energies of 0.8–8 MeV) on the Express-A2 geostationary satellite and Meteor-3M polar satellite. New radiation belts of relativistic electrons in the space (L ～ 3) between the stationary outer and inner belts were formed as a result of either superstorm (|Dst|_max = 373 and 289 nT). The position of the maximums of these belts (L _max = 2.9 and 3.1) coincides with the known dependence of L _max on the magnetic storm Dst variation amplitude: |Dst|_max = 2.75 × 10⁴/L _max ⁴ . In November–December the new belt very slowly (ΔL ～ 0.1 per month) shifted toward the Earth. During the series of moderate (～100 nT) magnetic storms that developed as a result of the extreme solar events in January 2005, the belt in the space shifted toward deeper L shells (L ～ 2.5). The moderate January storms produced new belts with L _max ≥ 4.  相似文献
