Lee waves with an asymmetrical “mountain”
How will lee waves look differently if we are using the asymmetrical mountain instead of the symmetric one? And is symmetry actually important at all or are we just looking…

Instructions: Lee wave demonstration in the GFI basement
This blog post is meant as guideline if someone other than me might have to set up this demonstration at some point… Have fun! :-) Lee waves Lee waves are…
Tank experiment: Lee waves in a fancy density (and dye) stratification
Did you seriously think we’d stop tank experiments with only 2-layer systems? Nooo! Today, the plan was to set up a continuous stratification, which I have been planning to do…
The one where it would help to understand the theory better (but still: awesome tank experiment!)
The main reason why we went to all the trouble of setting up a quasi-continuous stratification to pull our mountain through instead of sticking to the 2 layer system we…
Dead water — the fancy experiment including Nansen himself
Now that we do have a really awesome 12-layer 6-color stratification, we obviously had to do the dead water experiment again. This time we chose to include a not-too-happy-looking Nansen…
Lee waves in the tank
Did you guess what we needed the stratification for? Yes — we are moving mountains again! :-) What we want to look at: How a current reacts to an obstacle…
Wake of a house.
Am I weird for noticing that kind of stuff? When I posted that picture of the fountain in the last post, it very strongly reminded me of a breakfast my sister and I…
Details of lee waves in the tank.
A movie focusing on details of the lee waves in the tank. In this post, we investigated lee waves in a tank in a general way. Here, I want to…
Surface imprints of internal waves
How internal waves in the ocean can be spotted on the surface. Under certain conditions, internal waves in the ocean can be spotted at the ocean’s surface due to changes…
Internal (lee) waves in a tank.
Lee wave experiment in a large tank with a moving mountain. In this previous post, we talked about internal waves in a very simple experiment. But Geophysical Institute has a great…
