Effect of solar and galactic cosmic rays on the duration of macrosynoptic processes     

I. V. Artamonova  S. V. Veretenenko 《Geomagnetism and Aeronomy》2013,53(1):5-9

The effect of solar and galactic cosmic ray variations on the duration of elementary synoptic processes (ESPs) in the Atlantic-European sector of the Northern Hemisphere has been studied. It has been found that solar cosmic ray (SCR) bursts result in an increase in the duration of ESPs, which belong to the western and meridional forms of atmospheric circulation. Forbush decreases in galactic cosmic rays (GCRs) are accompanied by an increase in the duration of ESPs, which belong to the meridional atmospheric circulation form, and in a decrease in the duration of ESPs, which are related to the western and eastern circulation forms. It has been assumed that the observed variations in the ESP duration are caused by the effect of short-period cosmic ray variations on the intensity of cyclonic processes at middle and high latitudes, namely, the regeneration of cyclones near the southeastern coast of Greenland after SCR bursts and the development of blocking anticyclones over the northeastern Atlantic, Europe, and Scandinavia during GCR Forbush decreases.  相似文献

Pulsating magneto-dipole radiation of a quaking neutron star powered by energy of Alfvn seismic vibrations     

Sergey Bastrukov  Irina Molodtsova 《中国天文和天体物理学报》2011,(9)

We compute the characteristic parameters of the magneto-dipole radiation of a neutron star undergoing torsional seismic vibrations under the action of Lorentz restoring force about an axis of a dipolar magnetic field experiencing decay.After a brief outline of the general theoretical background of the model of a vibration-powered neutron star,we present numerical estimates of basic vibration and radiation characteristics,such as frequency,lifetime and luminosity,and investigate their time dependence on magn...  相似文献   

The geoelectric structure at the site of “Crystal” underground nuclear explosion (Western Yakutia) from TEM data     

N.O. Kozhevnikov  E.Yu. Antonov  S.Yu. Artamonova  A.E. Plotnikov 《Russian Geology and Geophysics》2012,53(2):185-193

The resistivity pattern at the site of the “Crystal” underground nuclear explosion (Daldyn–Alakit district of Yakutia) of 1974 which led to an accident has been imaged using TEM data. The local background pattern corresponds to a three-or four-layer earth with a conductor at the base. The uppermost layer, with a resistivity of tens to hundreds of ohm · m, has its bottom at 190–260 m asl and consists of perennially frozen Late Cambrian carbonates. The resistivity structure of shallow subsurface at the blast epicenter remained unperturbed though being subject to mechanic and thermal effects. The bottom of the second layer is at 20 to 190 m below the sealevel and its resistivity is 7–10 ohm · m. It is composed of frost-bound and unfrozen cold rocks that belong to a Late Cambrian water-bearing sequence (an aquifer). The third and fourth layers make up the conducting base of the section (0.2–1.4 ohm · m) while the conductor’s top matches the table of a Middle Cambrian aquifer. Anomalous transient response at the site prompts the existence of a local conductor possibly produced by highly saline waters in the containment cavity and in deformed rocks around it. However, the resistivity is too low (0.02 ohm · m) to be accounted for by any model available at the present state of knowledge. Another problem is to explain how the brines circulating at large depths may have reached the explosion cavity and the surrounding strained zones. The study has provided a first idea of the background resistivity distribution and its UNE-induced changes.  相似文献   

Middle-Upper Miocene stratigraphy of the Taman Peninsula, Eastern Paratethys     

Eleonora P. Radionova  Larisa A. Golovina  Natalia Yu. Filippova  Valery M. Trubikhin  Sergey V. Popov  Irina A. Goncharova  Yulia V. Vernigorova  Tatiana N. Pinchuk 《Central European Journal of Geosciences》2012,4(1):188-204

The stratigraphy of the Taman Peninsula is defined using the sections at Zelensky Hill ?? Panagia, Popov Kamen, Taman and Zheleznyi Rog. The stratigraphy is constructed from distribution of mollusks, foraminifers, nannofossils, diatoms, and organic-walled phytoplankton, as well as incorporating paleomagnetic data. The occurrence of oceanic diatom species in the Middle-Upper Sarmatian, Maeotian and Lower Pontian makes a direct correlation possible between the sections studied, the Mediterranean basin and oceanic zonation. The new data on planktonic and benthic biotic groups suggests a pulsating connection of the Eastern Paratethys with the open marine basins, especially during transitional intervals within constant environments. Comprehensive studies of the Chokrakian-Kimmerian microbiota provide evidence for several levels of marine microbiotic associations that are related to short-term marine invasions. The biotic and paleomagnetic data of the Taman Peninsula sections give a more comprehensive, but sometimes a controversial picture on the Eastern Paratethys history and the nature of its relationship with the adjacent marine basins.  相似文献

Permafrost and groundwater settings at the site of “Kraton-3” peaceful underground nuclear explosion (Yakutia), from TEM data     

S.Yu. Artamonova  N.O. Kozhevnikov  E.Yu. Antonov 《Russian Geology and Geophysics》2013,54(5):555-565

Geological and geophysical interpretation of TEM data has revealed changes to the subsurface from the “Kraton-3” peaceful underground nuclear explosion (PUNE). The explosion was conducted on 24 August 1978 at a depth of 577 m in Middle Cambrian limestone on the eastern periphery of the Tunguska basin (Western Yakutia). The site is located in an area of 100 to 300 m thick permafrost and pressurized aquifers with Na-Ca-Cl brines (up to 400 g/l TDS) and cryopegs. The “Kraton-3” epicenter is only 160 m away from a fault emerging along the Markha River.TEM responses collected at 22 stations along three profiles image a layered-earth background resistivity pattern. The highly resistive uppermost layer, ~ 150–200 m thick, consists of perennially frozen ice-rich rocks. Dry permafrost on watersheds of the Markha right side reaches 1200 ohm?m, while the hypsometrically lower frozen ground along the fault is 10 to 40 times less resistive. That is exactly the place of the PUNE epicenter, and the resistivity lows may record permafrost degradation and taliks (unfrozen layers).The layers below are conductive and correspond to Upper Cambrian and Middle Cambrian (I) aquifers with brines. The top of the Upper Cambrian aquifer along the central profile is highly variable in depth, especially along the fault on the river left bank. The data indicate a local groundwater anomaly above the explosion: the Middle Cambrian I brines, which show up as a conductor in the resistivity pattern, become ~ 300 m shallower, most likely rising along the rubble chimney above the UNE containment cavity; the lateral extent of the anomaly reaches 400 m. There may exist paths for mass and heat transport maintained by pressurized brines in the system “containment cavity–rubble chimney–fault zone–ground surface”.  相似文献
