Possibility of the investigation of interplanetary shock interaction with the earth's bow shock,magnetopause and plasmapause by means of a non-coherent response method     

J.V. Kovalevsky  T.V. Kuznetsova 《Planetary and Space Science》1977,25(7):657-662

The problem of interaction between the interplanetary shock of 8 March, 1970 and the Earth's bow shock, magnetopause and plasmapause is considered. Estimates are made using existing models of the moments of initial impulsive interaction of interplanetary shocks with the bow shock and of the secondary interaction of the resulting split discontinuities with the magnetopause, plasmapause and a modified bow shock. Using computed data on the plasma's concentration jumps at discontinuities and on the latters' velocities, estimates have been carried out of remote sounding and the response signals' phase difference change rates Δf (which were found to be of the order of ～ 10^?3?10^?2Hz) appearing on the radio path with a non-coherent response near the subsolar region. It has been ascertained that the non-coherent response method permits, by using generators with a stability of $\text{ε =}\text{δ}{}_{\mathrm{<mtext>r</mtext>}}\text{f}\text{f}{}_{\mathrm{<mtext>O</mtext>}}\text{= 10}{}^{\mathrm{?11}}\text{?10}{}^{\mathrm{?10}}$, effective investigation (with a good time resolution) of the impulsive interaction of interplanetary shocks with the plasma discontinuities of the bow shockmagnetopause-plasmapause system.  相似文献   

Influence of a high aerosol concentration on the thermal structure of the atmospheric boundary layer     

M. N. Khaikin  I. N. Kuznetsova  E. N. Kadygrov 《Izvestiya Atmospheric and Oceanic Physics》2006,42(6):715-721

The influence of increased concentrations of submicron aerosol produced by forest fires on thermal characteristics of the atmospheric boundary layer (ABL) in Moscow and its remote vicinity (the town of Zvenigorod) are analyzed on the basis of regular remote measurements of the ABL temperature profile with the use of MTP-5 profilers. In the air basin of a large city, additional aerosol and accompanying pollutants in early morning hours (at small heights of the Sun) most frequently did not cause substantial changes in the ABL thermal structure. In the locality remote from the megalopolis (Zvenigorod), the atmospheric pollution by aerosol led to noticeable changes in the ABL thermal characteristics. Especially strong changes were observed in the daytime, during the maximum supply of solar radiation. In morning hours, the heating rate of the lower 100-m layer of the polluted air exceeded the heating rate of a relatively pure air by more than one degree. In higher layers, the differences between the rates of temperature changes in a relatively clean atmosphere and in an atmosphere polluted by aerosol (in the suburb) were insignificant.  相似文献   

Ozone content over the Russian Federation in the second quarter of 2017     

A. M. Zvyagintsev  N. S. Ivanova  I. N. Kuznetsova  V. A. Lapchenko 《Russian Meteorology and Hydrology》2017,42(9):621-623

The review is compiled on the basis ofthe operation ofthe system that monitors total ozone (TO) in the CIS and Baltic countries and functions in the operational regime at the Central Aerological Observatory (CAO). The monitoring system uses the data from the national network equipped with M-124 filter ozonometers under the methodological supervision ofthe Main Geophysical Observatory. The quality of the functioning of the entire system is under the operational control based on the observations obtained from the OMI satellite equipment (NASA, USA). The basic TO observation data are generalized for every month of the second quarter of 2017 and for the quarter as a whole. The data of observations of surface ozone content carried out in the Moscow region and on the Black Sea coast of Crimea are also briefly presented.  相似文献   

Moscow Urban Heat Island: Detection,boundaries, and variability     

I. N. Kuznetsova  N. E. Brusova  M. I. Nakhaev 《Russian Meteorology and Hydrology》2017,42(5):305-313

The determination of the anthropogenic impact on the thermal regime of a megalopolis is discussed. The nominal boundaries of the megalopolis thermal effects are determined taking into account orographic and landscape effects and the variability of temperature difference between the center of the city and its suburbs. It is proposed to use the data of stations located within 40-50 km from the urban agglomeration boundaries for calculating the anthropogenic component of the urban heat island. The parameters of the heat island in Moscow are determined from the measurement data on maximum and minimum daily surface air temperature in 2012-2016, and their significant seasonal and intradaily variability is revealed. It is corroborated that anthropogenic causes for the higher air temperature in Moscow as compared with suburbs during the cold season are the release and loss of heat of heating systems; in the absence of snow cover the anthropogenic effect of these sources is enhanced by the thermal radiation of the urban surface.  相似文献   

Ozone Content over the Russian Federation in the Third Quarter of 2018

The review is compiled on the basis of the results of the operation of the total ozone (TO) monitoring system that covers Russia and adjoining territories and functions in the operational mode at the Central Aerological Observatory (CAO). The monitoring system uses data from the national network equipped with M-124 filter ozonometers being under the methodological supervision of the Main Geophysical Observatory. The quality of the system functioning is operationally controlled based on the OMI satellite equipment observations (NASA, USA). Basic TO observation data are generalized for each month of the third quarter of 2018 and for the third quarter as a whole. The data of routine observations of surface ozone values in the Moscow region, Crimea, and on the Kola Peninsula are also considered.  相似文献

Possibility of estimating the abundance of oxygen atoms and molecules based on electron density measurements in the middle atmosphere     

L. A. Shchepkin  G. P. Kushnarenko  G. M. Kuznetsova 《Geomagnetism and Aeronomy》2008,48(1):124-128

It has been tried to develop the method for estimating the ratio of the densities of oxygen atoms (n ₁) and nitrogen molecules (n ₃) as well as n ₁/n ₂ and n ₂/n ₃ (where n ₂ is the density of oxygen molecules) at the reference level of the upper thermosphere (120 km), using the data on electron density at altitudes of 120–200 km. This approach is based on an analysis of the semiempirical model (SEM) equation describing the dependence of electron density (N) on the characteristics of the thermospheric neutral gas. The series of the SEM versions [Shchepkin et al., 1997, 2004] was previously developed by the authors of this work. The estimates were performed based on the regular N measurements with the help of a digital ionosonde at ISZF SO RAN, Irkutsk, in 2003–2005.  相似文献
