Ali, This is great. Your students did a wonderful job with the paper. The SciAm editor added that Istanbul was the capital of Turkey, and she is very embarrassed by this mistake.
If any of your students want to go deeper, they can check my web site below, which includes the most recent work on this subject and a new paper (Toda et al, JGR, 2005) with 3 animations included.
Best,
