Description of a physical model of the magnetic-field structure that exists in the inner magnetosheath, near the earth-sun line, and during highly disturbed periods. Magnetometer data are presented in a new format that uses the ordinary inclination-declination coordinate system. Measurements of the inclination angle show how much the field lines are distorted from being tangent to the magnetopause. Distortions in the inclination angle sometimes exceed 45 deg in the low-field regions that are believed to be associated with plasma condensations or clouds. The magnetic field is usually within 15 deg of being tangent to the magnetopause in high-field regions, but some larger distortions have also been seen. The clouds usually appear to be extended along the average magnetic field direction.
