    Overview - Electric fields (1979)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-08-28
    Beschreibung: The electric fields session is designed to review progress in observation, theory, and modeling of magnetospheric electric fields, and to expose important new results. The present report comments on the state and prospects of electric field research, with particular emphasis on relevance to quantitative modeling of the magnetospheric processes. Attention is given to underlying theories and models. Modeling philosophy is discussed relative to explanatory models and representative models. Modeling of magnetospheric electric fields, while in its infancy, is developing rapidly on many fronts employing a variety of approaches. The general topic of magnetospheric electric fields is becoming of prime importance in understanding space plasmas.

    Solution of a few nonlinear problems in aerodynamics by the finite elements and functional least squares methods (1979)
    In:  CASI
    Details
    Publikationsdatum: 2019-08-28
    Beschreibung: The numerical simulation of the transonic flows of idealized fluids and of incompressible viscous fluids, by the nonlinear least squares methods is presented. The nonlinear equations, the boundary conditions, and the various constraints controlling the two types of flow are described. The standard iterative methods for solving a quasi elliptical nonlinear equation with partial derivatives are reviewed with emphasis placed on two examples: the fixed point method applied to the Gelder functional in the case of compressible subsonic flows and the Newton method used in the technique of decomposition of the lifting potential. The new abstract least squares method is discussed. It consists of substituting the nonlinear equation by a problem of minimization in a H to the minus 1 type Sobolev functional space.

    Application of space technology to crustal dynamics and earthquake research (1979)
    In:  CASI
    Details
    Publikationsdatum: 2019-08-28
    Beschreibung: In cooperation with other Federal government agencies, and the governments of other countries, NASA is undertaking a program of research in geodynamics. The present program activities and plans for extension of these activities in the time period 1979-1985 are described. The program includes operation of observatories for laser ranging to the Moon and to artificial satellites, and radio observatories for very long baseline microwave interferometry (VLBI). These observatories are used to measure polar motion, earth rotation, and tectonic plate movement, and serve as base stations for mobile facilities. The mobile laser ranging and VLBI facilities are used to measure crustal deformation in tectonically active areas.

    Lightning as an indication of storm severity (1979)
    In:  CASI
    Details
    Publikationsdatum: 2019-08-28
    Beschreibung: There is a substantial case for the theory that cloud electrification is related primarily to strong convection and the sizeable relative air motion that it implies; therefore, the electrification and subsequent discharge rates can be related to the air motion environment of thunderstorms. The isoceraunic contour map used by the WMO for observing and measuring thunderstorm occurrence contains no information on flash rates, flash density, flash relationship to storm severity, or flash variation with meteorological environment. A constant-view geosynchronous lightning mapper would permit simultaneous studies of the lightning discharge patterns and the meteorological environment of storms, thus establishing whether or not there is a reliable enough relationship to use the observed flash rates and characteristics as supplemental guidance for storm forecast refinement.

    The effect of errors in the assignment of the transmission functions on the accuracy of the thermal sounding of the atmosphere (1979)
    In:  CASI
    Details
    Publikationsdatum: 2019-08-28
    Beschreibung: In order to test the error of calculation in assumed values of the transmission function for Soviet and American radiometers sounding the atmosphere thermally from orbiting satellites, the assumptions of the transmission calculation is varied with respect to atmospheric CO2 content, transmission frequency, and atmospheric absorption. The error arising from variations of the assumptions from the standard basic model is calculated.

    On the acceleration of the auroral plasma of the Earth due to conic instability (1979)
    In:  CASI
    Details
    Publikationsdatum: 2019-08-28
    Beschreibung: The role of electrostatic conic instability in the diffusion of spilled particles and the acceleration of the auroral plasma of the Earth are numerically investigated by means of quasi-linear equations. Linear increments to the conic instability under magnetospheric conditions are introduced. The quasi-linear equation is averaged along tubes of force taking into account the drift across the magnetic field lines. It is shown that the existence of a conic instability leads to small spills and isotropic distribution of particles, but is also accompanied by significant acceleration of electrons.
