But there are places where persistent
katabatic winds flowing downwards from mountains rake the
surface so fiercely that the snow is lifted away from the continent altogether.
Over the coastal escarpment, the regression coefficients of temperature anomalies with the SAM are an indication that the SAM is tied with the
surface energy balance and modulation of the thermally direct circulation as described by Parish and Bromwich (2007); the
katabatic winds mix sensible heat towards the
surface to balance longwave cooling (van den Broeke et al. 2006).
