Zonal component of the thermospheric neutral winds as a function of latitude and longitude for 20:00 LT as modeled by HWM14. The winds are the same used by EZDrifts to produce the equatorial zonal drifts shown in Figures 2–4. Each panel represents one altitude and season. The altitudes are indicated on the top of each column of panels. The seasons are indicated on the right-hand side of each row of panels. The solid blue line indicates the location of the geomagnetic equator.
