Scientific paper

The solar wind quasi-invariant (QI) has been introduced as the energy density ratio QI=(B2/8π )/(ρ v2/2) [Osherovich, Fainberg and Stone, GRL, 26, 16, 2597, 1999]. B is the interplanetary magnetic field strength, v is the bulk velocity and ρ is the plasma density. The significance of this result has been supported by the studies of QI from 0.7 AU to 28 AU, using data from Pioneer-Venus Orbiter and the Voyagers [Fainberg, Osherovich and Stone, GRL, 28, 8, 1447, 2001; Fainberg and Osherovich, Proc. 10th European Sol. Phys. Mtg, ESA SP-506, vol. 1, 43, 2002]. Magnetic clouds have anomalously large values of QI of 10-100 times higher than QImedian because of their larger than average B and lower ρ due to the expansion. We report the contribution of high QI events (not only magnetic clouds) to the yearly QI based on hourly values of QI. The geomagnetic effectiveness of individual high QI events and their impact on geomagnetic indices will be discussed.
