Modeling of Magnetic Field Disturbances in Sheath Region of Interplanetary Magnetic Clouds of Elliptical Shapes
Abstract
It is widely accepted that magnetic disturbances around fast interplanetary magnetic clouds can play an important role in their geo-effectiveness. An analytical solution for magnetic field in the sheath region of a cylindrical magnetic cloud with an elliptical cross-section is proposed. Upstream magnetic field can have an arbitrary direction. Normal magnetic field components are conserved through the bow shock with a high accuracy.
