Plasma Sheet Dynamics
• How does mass, momentum and energy enter the magentosphere?– Reconnection
– Kelvin-Helmholtz Instability
– Kinetic Alfven Waves/Mode Conversion
QuickTime™ and aH.264 decompressor
are needed to see this picture.

Plasma Sheet Dynamics
• Entropy Definition global/total: S=p1/dv; specific/local: s = p/
• Entropy Crisis– Steady Convection– Substorm Transition
• How are ions heated?• What convects cold plasma to the center of
the plasma sheet?

Role of Heavy Ions
• At Magnetopause– Reconnection (Threshold/Growth)– KH inertial effects (Inertial Scale Effects)– Mode Conversion (Strong Absorption)
• At Planets– Mercury– Jupiter
