    Magnetic cloud passage at Earth and associated substorm activity (1992)
    In:  CASI
    Details
    Publication Date: 2004-12-03
    Description: An approach to the study of the solar wind-magnetosphere interaction by signal type, that is, by examining the effect in the magnetosphere of well defined interplanetary structures, is presented. Focus is on the response of the magnetosphere to interplanetary magnetic clouds. Among their properties are: the slow and smooth variation of the magnetic field vector, with fluctuation level well below common interplanetary values; the similarly well behaved bulk flow; the wide range of field and flow parameters; and the longevity of passage (1 to 2 days). If the magnetic cloud is oriented such that a long period of uninterruptedly northward pointing field is followed by a long interval of continuously southward pointing field, then the transition of the magnetosphere from a quiescent state (the 'ground state') to a very active state can be studied, the latter being sustained by continued forcing from the magnetic cloud. A synopsis of the main findings of a recent study in such an interaction is given, concentrating on the substorm activity attending the second part of cloud passage.

    FMRFamide-like immunoreactive nervus terminalis innervation to the pituitary in the catfish, Clarias batrachus (Linn.): demonstration by lesion and immunocytochemical techniques (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: Certain thick FMRFamide-like immunoreactive fibers arising from the ganglion cells of nervus terminalis in the olfactory bulb of Clarias batrachus can be traced centripetally through the medial olfactory tract, telencephalon, lateral preoptic area, tuberal area, and hypothalamohypophysial tract to the pituitary. Following 6 days of bilateral olfactory tract transection, the immunoreactivity in the thick fibers, caudal to the lesion site, was partially eliminated, whereas after 10 and 14 days, it was totally abolished in the processes en route to the pituitary. The results indicate a direct innervation of the pituitary gland by the FMRFamide-like peptide containing fibers of the nervus terminalis.

    Dayside ionospheric convection changes in response to long-period interplanetary magnetic field oscillations - Determination of the ionospheric phase velocity (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: Ground magnetic field perturbations recorded by the CANOPUS magnetometer network in the 7 to 13 MLT sector are used to examine how reconfigurations of the dayside polar ionospheric flow take place in response to north-south changes of the IMF. During the 6-h interval in question, IMF Bz oscillates between +/- 7 nT with about a 1-h period. Corresponding variations in the ground magnetic disturbance are observed which we infer are due to changes in ionospheric flow. Cross correlation of the data obtained from two ground stations at 73.5 deg magnetic latitude, but separated by about 2 hours in MLT, shows that changes in the flow are initiated in the prenoon sector (about 10 MLT) and then spread outward toward dawn and dusk with a phase speed of about 5 km/s over the longitude range about 8 to 12 MLT, slowing to about 2 km/s outside this range. Cross correlating the data from these ground stations with IMP 8 IMF Bz records produces a MLT variation in the ground response delay relative to the IMF which is compatible with these deduced phase speeds.

    Radial expansion of an ideal MHD configuration and the temporal development of the magnetic field (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: We study the free radial expansion of a 3-component magnetic configuration. The emphasis of this paper is on the behavior of a field undergoing non-self-similar expansion. Comparing our results with the evolution of a magnetic configuration expanding self-similarly, we find that self-similar expansion appears as the asymptotic limit (with time) of the general case. Using a model field we show that a non-self-similar velocity profile need not have a strict monotonic decrease with time.

    Global distributions of upper tropospheric relative humidity derived from SAGE II observations (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: The global distributions of upper tropospheric relative humidity derived from the archived SAGE II water vapor data set are presented. For both summer and winter months, vertical profiles of zonal mean relative humidity are derived for each of the six 20-deg latitude bands covering 60 deg N - 60 deg S. Some examples of global maps of upper tropospheric relative humidity are shown to illustrate the relationship between moist areas and convective activity.

    Stratospheric temperature increases due to Pinatubo aerosols (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: Northern-Hemisphere stratospheric temperatures at 30 and 50 mb beginning in June 1991 are compared with 20-year (1965-1984) and 26-year (1964-1989) monthly means. Significant temperature increases are shown in July, August, September, and October for latitudes from approximately 30 deg N to the equator. In September and October deviations are observed for large areas between the equator and 30 deg N, with temperature increases as high as + 3.5 C occurring at some locations. The monthly averaged zonal mean 30-mb temperatures at 20 deg N in September and October were approximately 2.5 C higher that the 26-year mean, with some daily zonal mean increases of almost 3 C. Higher values occurred equatorward of 20 deg N. These warmings are due to absorption of radiation by the aerosols produced from the June eruptions of the volcano Pinatubo (15.1 deg N, 120.4 deg E) in the Philippines. Stratospheric warmings are expected to be occurring simultaneously at southern latitudes, especially from the equator to about 20 deg S, based on satellite and lidar measurements of the locations of the new aerosol layers. These localized temperature increases should decrease in magnitude and become more global as the cloud disperses globally and spreads in altitude.

    Initial assessment of the stratospheric and climatic impact of the 1991 Mount Pinatubo eruption - Prologue (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: An overview is given of the techniques employed to evaluate the early effects of the volcanic eruption on the stratosphere and climate, and data are given on the initial eruption yield. Global satellite measurements were taken by TOMS, SAGE II, AVHRR, and other devices, and the initial results indicate an eruption yield of 20 megatons of SO2 and 20-30 megatons of H2SO4/H2O aerosol mass. The predicted effects of the eruption - accelerated global ozone depletion and surface cooling - can be compared to meteorological data to test the validity of present climate models based on these data.

    SAGE II measurements of early Pinatubo aerosols (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: SAGE II satellite measurements of the Mt. Pinatubo eruption cloud in the stratosphere during June, July, and early August 1991 show that aerosols in the tropics reached as high as 29 km altitude with most of the cloud between 20 and 25 km. The most optically thick portions of the cloud covered latitudes from 10 deg S to 30 deg N during the early part of this period. By late July, high stratospheric optical depths were observed to at least 70 deg N, with the high values north of about 30 deg N from layers below 20 km. High pressure systems in both hemispheres were observed to be correlated with the movement of volcanic material at 21 km into the westerly jet stream at high southern latitudes and similarly to high northern latitudes at 16 km. By August, the entire Southern Hemisphere had experienced a 10-fold increase in optical depth relative to early July due to layers above 20 km. Initial mass calculations using SAGE II data place the aerosol produced from this eruption at 20 to 30 megatons, well above the 12 megatons produced by El Chichon.

    Excitation and decay of flows in the magnetosphere-ionosphere system due to magnetic reconnection at the dayside magnetospause and in the geomagnetic tail (1992)
    In:  CASI
    Details
    Publication Date: 2004-12-03
    Description: The excitation and decay of flows in the magnetosphere-ionosphere system which are caused by magnetic reconnection at the dayside magnetopause and in the geomagnetic tail are applied. Following an outline of the theoretical framework recently introduced by Cowley and Lockwood, their ideas are applied to the discussion of the time dependent flows generated by both impulsive and quasicontinuous reconnection.
