Reconstruction of the space and time variability of thermohaline fields in the Sevastopol Bay     

É. N. Mikhailova  N. B. Shapiro 《Physical Oceanography》2008,18(5):255-271

The aim of the present work is to reconstruct the space and time variability of the three-dimensional fields of currents, temperature, salinity, and density in the Sevastopol Bay under the influence of the actual external factors in 1999. For this purpose, we use a version of the numerical multilayer model on the σ-coordinates. A vast array of the data of observations accumulated as a result of regular monitoring of the Sevastopol Bay contains, in particular, the data on the sea-surface temperature measured with six-hour intervals (at the hydrometeorological station located near the center of the bay) and almost monthly vertical profiles of temperature and salinity obtained at seven hydrological stations. The comparison of the numerical results with the data of observations enables us to conclude that, in general, the model fairly correctly describes the space structure and rearrangements of the fields of temperature and salinity. Among the most important distinctions, we can mention the fact that the fresh river water penetrating into the bay is mixed with seawater faster than predicted by the model. We also discuss the causes of these distinctions. Translated from Morskoi Gidrofizicheskii Zhurnal, No. 5, pp. 23–39, September–October, 2008.  相似文献   

Distribution of type Ib/c supernovae relative to galactic spiral arms     

G. A. Mikhailova  O. S. Bartunov  D. Yu. Tsvetkov 《Astronomy Letters》2007,33(11):715-719

Type Ib/c supernovae are shown to be concentrated to the inner edges of the spiral arms, with the distributions for type Ib and Ic supernovae being identical. We have found differences between the distributions of type II and Ib/c supernovae relative to spiral arms, suggesting that the type Ib/c presupernovae are, on average, younger.  相似文献

Water circulation, sediment dynamics, erosional and accumulative processes in the Gironde Estuary (France)     

M. V. Mikhailova  M. V. Isupova 《Water Resources》2006,33(1):10-23

The basic features of the hydrological regime and morphodynamics of the mouth area of the Garonne and Dordogne rivers and its part, i.e., the Gironde Estuary, are discussed. The main attention is given to the analysis of water circulation and sediment dynamics in the Gironde Estuary under the joint impact of seasonal river flow and tidal fluctuations. In addition to this, the estuary evolution during the Holocene period and regularities of present-day erosional and accumulative processes are characterized.  相似文献   

Hydrological and morphological processes at the Zhujiang River mouth area, China   总被引：1，自引：0，他引：1  

V. N. Mikhailov  M. V. Mikhailova  V. N. Korotaev 《Water Resources》2006,33(3):237-248

Hydrological and morphological processes in the Zhujiang River (Pearl River) mouth area of China are discussed. The hydrological regime of the Xijiang River, which is the largest river of South China and the main source of water inflow into the Zhujiang mouth area, is described. The basic features of the hydrological regime of the delta and the near-shore zone of the Zhujiang River mouth are characterized, much attention being given to the role of tides and mixing of river and sea water in the hydrological regime. Special emphasis is placed on morphodynamic processes at the mouth area and the history of the Zhujiang Delta evolution.  相似文献   

Electric and electromagnetic processes in the near-Earth atmosphere before earthquakes on Kamchatka     

Yu. M. Mikhailov  G. A. Mikhailova  O. V. Kapustina  G. I. Druzhin  S. E. Smirnov 《Geomagnetism and Aeronomy》2006,46(6):796-808

Simultaneous records of the diurnal variations in the quasistatic electric field in the near-Earth atmosphere, fluxes of discrete electromagnetic pulses in the VLF band, source azimuths, narrowband filter output emission intensity at frequencies of 4.65 and 5.3 kHz, and time forms and spectra of VLF pulses have been analyzed. The anomalous behavior of these parameters in October 2002 and August 2004 with different time delay was accompanied by earthquakes near the southeastern coast of Kamchatka at distances of 250–400 km from the registration points. Based on the results of a fine frequency-time analysis of the broadband records of VLF signals, it has been indicated for the first time that discrete electromagnetic pulses observed in anomalous fluxes before earthquakes were signals of local thunderstorm processes.  相似文献

Hydrological Regime of the Nile Delta and Dynamics of Its Coastline     

Mikhailova  M. V. 《Water Resources》2001,28(5):477-490

General information on the Nile River basin is presented. Specific features of the morphological regime of the Nile Delta and its near-shore zone, as well as the delta water balance and groundwater regime are discussed. The dynamics of the sea coastline of the Nile Delta is described in great detail. It is shown that the recent delta of the Nile and its sea coastline have been formed under the joint impact of the eustatic sea level rise, subsidence of sediments in the northern part of the deltaic plain, and considerable decrease in the river sediment runoff after the construction of the Aswan High Dam.  相似文献
