North Atlantic oscillation and the Moroccan High Atlas

A recent client of ours on a ToubkalMountainGuides trip where we endured fresh deep snow (yes we are talking about the Moroccan High Atlas!), reminded us of the North Atlantic oscillation. Of course!

So here's the Wikipedia link for some light reading. Certainly it would appear from the winter of 2008/9 that the NAO index is low. Westerlies are suppressed and cold winters and storms track southerly toward the Mediterranean Sea. This brings increased storm activity and rainfall to southern Europe and North Africa.

Oh yes!
