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
