Заглавие: Dependence of High-Latitude and Low-Latitude Geomagnetic Disturbances on Solar Wind Parameters during the Magnetic Storm of November 7-8, 2004

Количество страниц: 4 с.

By global geomagnetic observation data the variations of intensity and dynamics of auroral electrojets, low-latitude disturbances at latitudes ~10-55°, SYM-H and studied. It is shown that positive values of SYM-H and Dst or the decrease of their negative values correspond to the growth period of Pd. The enhancement of magnetic field depression at latitudes Ф'~10-30° with the maximum ∆H in the evening sector is observed at negative values of IMF Bz and is accompanied by the enhancement of auroral electrojets in all temporal sectors and their southward shift. The maximum values of Dst ~-400 nT correspondent to the most intensity of western (eastern) electrojet in the midnight (evening) sector with a current center at the lowest latitudes. The possible sources of Dst and SYM-H variations are discussed.

Заглавие: Dependence of longitudinal localization of substorm center on geosynchronous orbits on the IMF Bγ-component

Количество страниц: 4 с.

The dependence of the longitudinal substorm center localisation on geosynchronous orbits on the IMF Bγ-component has been studied. It is shown that the local magnetic time of the longitudinal substorm center localisation in the magnetosphere varies from evening hours to morning hours as the Bγ-component increases. At low solar wind speeds the substorm centers localize nearer to the evening sector. The ionospheric projection of the substorm center magnetospheric localisation shifts westward at By0. Maximum longitudinal shifts of substorm centers in the ionosphere relative to their location in the magnetosphere are - 3.5 h at Bγ=-4 nT and 3.5 h at Bγ=4.4 nT. Thus, the change of the substorm center localisation relative to the midnight in the ionosphere is caused by both the change of the substorm center position in the magnetosphere and a turn of the magnetotail relative to X-axis.

Заглавие: Dependence of semi-diurnal variation of auroral absorption on a geomagnetic disturbance

Количество страниц: 4 с.

From data of riometer observations from 1986 to 1993 at stations of Kotelny Island, Tixie Bay and Zhigansk the semi-diurnal variations of occurrence frequency of auroral absorption and their dependence on geomagnetic activity have been determined. It has been found that the phase of semi-diurnal variation maximum is systematically shifted to earlier hours with the rise of geomagnetic disturbance. The reason of this experimental fact is discussed.

Заглавие: Dynamics of the field-aligned current during substorms with a sharp onset of the expansion phase

Количество страниц: 4 с.

By using satellite magnetic field measurements it is shown that before the substorm expansion phase onset the field-aligned currents of zone 2 type are not always observed on the geosynchronous orbits at the midnight sector. The relationship between the appearance of the field-aligned currents of zone 2 types before the beginning of the substorm expansion phase and the active phase duration and the preceding magnetic disturbance level has been found. It is found that if the expansion phase lasts less than 11 min, the appearance probability of the field-aligned current of zone 2 type before the substorm expansion phase onset T0 decreases. As the geomagnetic activity rises before a substorm, the probability of the beginning of the field-aligned currents before T0 increases. These results indicate that substorms in which the field-aligned currents of zone 2 type the T0 onset are absent, can be probably developed in the distant part of the magnetotail.

Заглавие: Dynamics of the Field-Aligned Current Systems Observed during The Super-Storm on Nov. 20, 2003

Количество страниц: 4 с.

Spatial distribution in the polar ionosphere of field-aligned currents density is studied by using data of the events on 20.11.03. Observable distributions are described in terms of three Regions of Iijima and Potemra, with taken into account in each Region of three types of spatial inhomogeneities. These inhomogeneitie were overlooked earlier. Dynamics of classical substorm current wedge SCW1, and the "current wedges" SCW2 and SCW3, both creating a polarization and amplification of the westward auroral electrojet, are described.

Заглавие: Dynamics of the Ionospheric Convection Systems Observed during The Super-Storm on Nov. 20, 2003

Количество страниц: 3 с.

In the accompanying Papers 1 and 2 was fulfilled timing of the 20.11.05 super-storm. Were detected 4 various types of the magnetospheric disturbances observable at southward IMF, and presented a new model of the field-aligned currents density spatial distribution in the polar ionosphere. In this paper are described the ionospheric convection systems, characteristic for the above various types. Are mentioned the mesoscale spatial inhomogeneities, which are observed more or less regularly but have not been mentioned in the past literature.

Заглавие: Early migrations to America in the light of a study of the Dyuktai paleolithic culture in Northeast Asia

Количество страниц: 13 с.

The most ancient monuments of Duktai culture were found in North America - in Alaska and the adjacent territories of Canada. At present, scientists have almost no doubt the assumption that it was from Northeast Asia (from Yakutia through Chukotka and Alaska) that the initial settlement of the New World by man took place. It is considered an axiom that America was originally deserted and that the continent was inhabited by a man of a modern physical type (Homo sapiens) from Asia through the areas adjacent to the Bering Strait, along the Bering Land Bridge connecting Chukotka with Alaska.
Древнейшие памятники дюктайской культуры найдены и в Северной Америке — на Аляске и прилегающих к ней территориях Канады.В настоящее время у ученых почти не вызывает сомнения предположение, что именно из Северо-Восточной Азии (из Якутии через Чукотку и Аляску) происходило и первоначальное заселение человеком Нового Света. Считается аксиомой, что Америка изначально была безлюдной и что континент был заселен человеком современного физического типа (Homo sapiens) из Азии через области, примыкающие к Берингову проливу, по Берингийскому сухопутному мосту, соединяющему Чукотку с Аляской.
