Comparison of oblique spread structure (OSS) velocities with horizontal neutral winds determined by the HWM14 model at heights and times of observations for a Tucumán and b Taiwan. Values determined by the time delay method shown in blue; velocities determined by the tilt method shown in magenta. The dashed line marks the spread velocity equal to the HWM14 neutral wind model velocity
