The response of the total ozone (TO) at subarctic latitudes to volcanic eruptions, products of which were injected into the
stratosphere, is analyzed. It is established that the behavior of the series of average annual TO values according to the
TOMS, SCIAMACHY, and GOME space equipment data averaged for 55°–65° N latitudes agrees with the activity of explosive volcanic
eruptions. The series of the TO satellite monitoring instrumental data are extended by 200 years into the past using a reconstruction
from the dendro-chronologic data. An analysis of the series of TO reconstructed values indicates that volcanogenic perturbations
of the subarctic ozonosphere initiate long-term negative TO deviations. In this case, the TO negative deviation depth depends
on the frequency of the ozonosphere volcanogenic perturbations and the phase of quasiperiodic oscillation cycles rather than
on the strength of a single volcanic explosion. 相似文献

Prior to extension of the lithosphere in the Eurasia Basin, the Yermak Plateau was an element of the Eurasian Arctic margin. Extension of the Barents Sea shelf culminated gradually in rifting of the continental crust with separation of this block from the continent during Chrons C25r?C26n (57.656?59.237 Ma ago) and emplacement of numerous basic dikes, which could be responsible for the formation of high-amplitude magnetic anomalies on the Yermak Plateau. The investigation included reconstruction of axes in the breakup zones along peripheral continental fragments of Spitsbergen with determination of the Euler poles and angles of rotation, which describe the kinematics of this process. It is revealed that the difference between depths of conjugate isobaths can be as large as many tens of meters, which reflects the nonuniformly scaled slide of peripheral areas of the continental crust along the plane of the crustal-penetrating fault and, correspondingly, their different subsidence during rifting. 相似文献

In this work, we evaluate the impact of terminated oceanic heat flux in the North Atlantic and Barents Sea on the Northern Hemisphere climate in January by numerical experiments with a coupled model of atmospheric general circulation and a thermodynamic model of the upper mixed layer of the ocean. We analyze the variations in the atmospheric circulation and near-surface temperature. We found that the termi-nation of the oceanic heat flux leads to a depression in atmospheric centers of action in the Northern Hemi-sphere (by 3?C5 hPa) and a significant cooling over the continents with the strongest temperature decrease down to ?10°C in northwestern Eurasia. 相似文献
