Lecture 3 Introduction to Magnetic Storms

Lecture 3 Introduction to Magnetic Storms. An isolated substorm is caused by a brief (30-60 min) pulse of southward IMF. Magnetospheric storms are large, prolonged disturbances of the magnetosphere caused by variations in the solar wind. Many storms follow coronal mass ejections.

Positive/Negative Effects of Solar Wind Density on Auroral Electrojets

Positive/Negative Effects of Solar Wind Density on Auroral Electrojets. RU (RL) is the rate of change of the AU (AL) index per unit solar wind density. The rates are small for northward IMF. As the southward IMF becomes larger, the distribution bifurcates.
