Geophysical investigations on manned spacecrafts

Summary Review has been made of the first results and perspectives of investigations in geophysics and bordering sciences (geology, geography, agrobiology, etc.) by means of manned orbital space laboratories. Relatively detailed discussion is given to the problems of the interpretation of terrain feature pictures from space. Attentively considered are the technique and results of the photometric processing of atmospheric photographs near the horizon with the purpose of studying atmospheric optical non-homogeneities (in particular, aerosol layers). The possible investigations based on the use of data about the outgoing radiation spectra are mentioned. (, , .) . . ( , ) . .

Inverse problems of satellite meteorology

Summary The paper presents a review of the possibilities of using meteorological satellites for investigating various atmospheric phenomena and obtaining data on the physical condition of the atmosphere required for realizing the numerical methods of weather forecast, the synoptical analysis and other purposes. To avoid repetition the review does not include the much important material in the field of satellite meteorology which had been dealt with in earlier reviews.

Automation of measuring the temperature dependence of electrical conductivity of rocks using a PMD-85-1 microcomputer

Summary The new for measuring the electrical conductivity of rocks and minerals developed in the Geophysical Institute is briefly discussed. Unlike the earlier method it uses a PMD-85-1 microcomputer and related equipment (all of CMEA production), which enable the automatic control of the experiment, collection, evaluation, graphic display and storage of the results. This method is verified by measuring the electrical conductivities of granitoids.

Constraints to the three-dimensional non-hydrostatic density distribution in the earth

Summary The paper is concerned with the properties of a density distribution within the Earth. A system of density parameter constraints involving Stokes' coefficients of the gravity field and the parameters describing the Earth's figure is derived. A density model, whose parameters fit these constraints, accounts for the fine structure of the gravity field and Earth's figure. Additional condition imposed on the average spherical density model are derived; they guarantee that the average spherical model is compatible with the 3-D density model.

Magnetic field at the core boundary in the nearly symmetric hydromagnetic dynamo z

Summary The behaviour of the poloidal and toroidal magnetic field at the core-mantle boundary is analysed in more detail, assuming that the conductive layer in the lowest mantle is thin. We can conclude that, in the case of the Z-model of the nearly symmetric hydromagnetic dynamo, the poloidal field may be considered potential everywhere in the mantle and that the azimuthal field depends on the geostrophic azimuthal velocity in the same manner as derived in[1] and[3].

On the entrainment in cumuli — A contribution to a case study

Summary The case study presented here is related to the thermodynamic analysis of entrainment and mixing in a shallow cumuls layer. The fair weather situation on 9. 9. 1983, Voves, is characterized by a field of scattered cumuli of the same depths and by a towering isolated cumulus. The clouds were sampled. Two types of analysis were used, the Paluch analysis and saturation point analysis, both of them making use of conserved parameters and a mixing line structure. Both methods gave similar results. For the small cumuli, lateral entrainment prevailed up to the highest penetration level while in the isolated cumulus, cloud top entrainment was the dominant mixing mechanism.

The connection between characteristic values of the 11-year cycles of solar and of geomagnetic activity

Summary Using the annual values of the indices of solar and geomagnetic activity for the period 1868–1976, the basic values characterizing the cycle as a whole were determined for the 11-year cycles nos 11–20, (Tab. 1). High values of the coefficients of correlation were found for some pairs of characteristic values of the same and different kinds, given in Tab. 2, which can be utilized for long-term predictions of geomagnetic activity.

Influence of the IMF sector boundaries on cosmic rays and tropospheric vorticity

Summary The effect of the IMF sector boundary crossing (IMF SBC) in the vorticity area index (VAI) — the well-known dip in the VAI after IMF SBC — is found to be independent of the IMF SBC effect in the cosmic ray flux. This finding refutes a recent suggestion by Lundstedt [1] that the IMF SBC effect in VAI is caused by a decrease in cosmic ray flux, but supports the concept of the IMF SBC effects in the ionosphere and atmosphere developed by Latovika [2–4]. Cosmic rays seem to affect the troposphere in another way.

Summary A formation of ice particles on artificial deposition INis described. INacting in dependence on the temperature and supersaturation over the ice are considered in the 1 D SSconvection cloud model with detailed microphysics including freezing. The limiting influence of the water vapour pressure upon the concentration of active INis shown resulting from the dependence of water vapour pressure on the ice particle concentration.
