Magnetic field and plasma parameters for magnetic clouds in the interplanetary medium

Abstract

For a set of 16 magnetic cloud events measured at 1 AU we investigated the magnetic field and plasma parameters in order to characterize the pressure differences between the structure and the environment. The asymmetry profile of the magnetic cloud field strength seems to be related to the magnetic pressure difference between the front and the rear medium, possibly by a compression process.
