Introduction Continued
Balance of forces on neutral winds in the ionosphere Pressure Gradient
Ion-Drag
Coriolis Force
Viscosity
Methods
TIE-GCM ran with different solar activity and night time ionization levels to provide variable values
Calculate neutral wind accelerations using model outputs
Determine which force(s) are responsible for the wind shear using plots and possibly statistical analysis
Richmond et al. 2015
Wind Shear
Accelerations
