== Foehn wind or Katabatic wind == 

 In the articles on Santa Ana winds it is made clear that this phenomenon is not constitute Foehn winds, but are katabatic winds, as their hot, dry character is not due to flowing across mountain ranges and consequently losing moisture on the ascent, but rather as a result of mechanical compression of subsident air as it descends from the interior plateau. I would argue that at least some  if not most  berg wind events are caused by outflow of air from the interior plateau, where the Kalahari High dominates during winter. However, at times, berg winds may result from moist air ascending the Drakensberg,or other eastern mountain ranges, as it is advected onshore by a ridging South Indian or South Atlantic High, and then subsequently descending the western escarpment, devoid of moisture, causing occasional searing mid- and late-summer heat along the western coastal belt (in towns such as Paarl, Wellington, Vredendal, Clanwilliam and Vioolsdrif)
