Q ь Pig. 3. Dendrog rams for the geomagnetospheric storms 15-18.02.1967: for the full period (а-precise, d-rough); precise dendrograms f o r the background - c, the initial phase - d, m a i n phase - e, r ecovery phase - f. represented by D ^ - i n d e x of geomagnetic activity, by the field of geomagneto spheric ring-current D R = 2 / 3 D gt-0.02v\/n+20 an d by the function of energe inje ction into geomagnetosphere pjibfedDR/dt+DR/'T, where. T = 6 h is a constant of ring-current decay time. Ionosphere has b e e n r e p r esented by AE- and AL- indices an d the whole m agnetospheric-ionospheric r e g i o n by the full value of dissipating energy u t = -4'102 0 ( d D R / d t + D R /т) + 3 A E - 1 0 15 (erg/s). G e o m a g netic field D s1j v a r i a t i o n has be e n used as a base physical process dividing the whole complicated GMS phenomenon into separate stages. Individualisation of each GMS consisted of: a) concrete physical characteristics of its succe ssive phases on the base of precise dendrites wi t h the account of the connec tions stability facts revealed using "rough" dendrites; b) analysis of the most sharp and demonstrative differences b e t w e e n phases; c) estimation of the c ontributions of a separate phases into the whole picture of the phenomenon; 85
