Here is a finite element simulation of strong winds in the Scharffenbergbotnen blue ice area.
Simulations made by Torsten Malm (Aalto Univ.) and Thomas Zwinger (CSC - IT Center for Science) using Elmer, animation made by Jyrky Hokkanen (CSC). [Thesis]
It so happens that i have some validation data. But first lets take a view of the valley from one of the northernmost nunataks (North is the left side of the youtube video).
Photo taken from one of the peaks in the left side of the video (on a nice day).
The camp was on the moraine to the left of the icefall in the back of the valley.
The strong winds in the deep end of the valley are roughly located where we had a camp in 2006/7.
After a particular violent storm we came back to our camp and found:
So yep ... the model is right!
There are definitely very strong winds where it predicts it should be.
