  1. Statistics are from linear regressions of wind support in relation to route × direction. Overall model statistics are provided, along with the coefficients for factors. Coefficients represent the change in wind support in km h−1 when moving from eastern (reference) to Himalayan routes or from northward (reference) to southward migrations. Non-significant models or coefficients are shown in bold.
