Internal lee waves in a tank experiment

Another tank experiment that is run in GEOF213 this fall is the one where we are moving mountains. Or at least one mountain. Read last year’s students’ account of the experiment here!

We move the mountain through stagnant water in a tank in order to simulate the flow of water over a ridge. This creates internal waves in the “lee” of the mountain.

Watch the movie below to get an impression of how cool this looks! And don’t be confused by the split screen after the time lapse ends, I was trying to give you the best of both cameras at once…

Instructions for how to set up the experiment can be found here.
