Rotating tank experiments on a cone

I had so much fun playing with rotating tank experiments on a cone this afternoon! And with Torge Martin (who I have the awesome #DryTheory2JuicyReality project with) and Rolf Käse (who got me into tank experiments with an amazing lab course back in 2004, that I still fondly remember). We tried so many different things, […]

Topographic Rossby wave

Finally trying the topographic Rossby wave experiment I wrote about theoretically here! And it is working — ok-ish. If you know what you are looking for, you can kind of see it. So check out the picture above so you know what you expect to see below ;-) We are rotating the tank fairly rapidly […]

Vorticity and Rossby waves

mglessmer — Wed, 21 Aug 2019 16:02:10 +0000

Usually when we talk about waves on this blog, we talk about surface- or sometimes internal waves, but my waves almost always oscillate vertically. Today, we’ll mix things up a little: Rossby waves are waves in the horizontal plane. They exist for example as oscillations on the atmosphere’s jet stream. In order to understand what […]

On vorticity

mglessmer — Mon, 25 May 2015 09:37:51 +0000

I’ve promised a long time ago to write a post on vorticity (Hallo Geli! :-)). So here it comes! Vorticity is one of the concepts in oceanography that is often taught via its mathematical formulation, and which is therefore pretty difficult to grasp for those of us with less mathematical training. But it’s also a […]

On drawing on the board by hand in real time

mglessmer — Mon, 14 Oct 2013 04:48:26 +0000

Drawing by hand on the board in real time rather than projecting a finished schematic? It is funny. During my undergrad, LCD projectors were just starting to arrive at the university. Many of the classes I attended during my first years used overhead projectors and hand-written slides, or sometimes printed slides if someone wanted to […]
