УДК550.385.007 Cluster c l assification methods as adequate instrument of investigation of system physical phenomena connected w i t h geomagnetospheric storms and aubatorms. Kov a l e v s k y I . V . , Morozov Yu.I., Pedoeeeva M.K. - Вкн. : Поляр ныегеомагнитныевозмущенияисвязаныеснимиявления. Апатиты, изд. КольскогонаучногоцентраАНСССР,' 1989, с. 83-87. The effectiveness of cluster (dendritic) method usage in the inveetignti** on of geomagnetic storms and aubatorms, con s idered as a complex Interconnec ted set of 29 plasma processes in the syste m interplanetary m e d i u m geomagneto' ephere-ionoephere, ia shown by a n example of two events. We have man a g e d to reveal a n important role of the solar w i n d temperature end of the I M P B x component in the development of magnetospheric disturbances (DR-field, Dst-, AE- and AL-indices).

Апатиты, изд.КольскогонаучногоцентраАНСССР, 1989,с. 0.88-91. The m a i n peculiarities of the auroral to r c h structures are shown. The results of height measurements of the torch using triangulation me t h o d are given. The cause of pulsating luminosity appearance inside the torches is discussed. Pig, - 4, Ref. - 6.

The w o r k suggests a c lassification of the observed types of bl a c k auroras. The mostly frequent types, black bands, are described in details. Geometric parameters of various forms are g i v e n as w e l l as life-time and drift velocities of black auroras. The model of potential double laye r of a V-shape is discussed as a me cha n ism responsible for black auroras. Pig. - 4, Ref. - 7. УДК550.388.2 A possible m e c h a n i s m of ionospheric ion i zation density variations caused by sudden commencement. Danov K.D., Kar t a l e v M.D. - ВкнПолярные геомагнитныевозмущенияисвязаныеснимиявления. Апатиты, изд.Коль скогонаучногоцентраАНСССР, 1989, с.95-101. A m e c hanism is pr o p o s e d f o r explaining ionospheric effects launohed by sudden cohmeaceinent. A n e w conception ia a pplied for modeling horizontally travelling disturbances i n the neutral ionospheric component leading to p e r t urbations of solitary wave type. Th e n the vertical ionization density dis tribution is obtained by numerical solving of the electron density equations under some model conditions. The wave parameters depend finally on one parameter - the total energy input. A c o m parison wi t h theoretical conclusions derived fr o m different model as we l l as w i t h experimental measurements of real ionospheric disturbances is presented. Pig. - 9, Ref. - 7. 125
