Strong gusts of wind -> lots of energy transferred to the water -> wind waves with large amplitudes

mglessmer — Sun, 08 Sep 2019 06:11:56 +0000

We are still in the “interesting weather” period here in Kiel. Feels more like April than like September, but I am not complaining. I love the rapid change between dark clouds and blue skies and sunshine! Also I like how much more interesting wave pattern get if the wind comes in gusts rather than blowing […]

From wind-driven capillary waves to gravity waves on a calm lake

mglessmer — Sat, 17 Aug 2019 16:10:13 +0000

The picture above I thought was too pretty to not put on my blog (because my blog’s main function to me is still my personal brain dump), but the picture below is actually interesting from a physics point of view. In the middle of the lake, the surface looks a lot rougher and crumpled than […]

Observing a breeze making waves on Parsteiner See

mglessmer — Wed, 05 Jun 2019 18:29:18 +0000

Yesterday, I happened to be at Parsteiner See for work. At first, the sea was completely calm and the only waves were the ones we made doing our photo shoots, like so: Other than that, the lake was completely calm. But then suddenly, I spotted a breeze going over the lake. It becomes visible in […]

Wind-driven waves in natural flumes for #flumefriday

mglessmer — Fri, 31 May 2019 13:05:39 +0000

On a bike tour with my friend Frauke in Greetsiel two or three weeks ago, she pointed out how well one could see that the waves on the puddles left in the Wadden Sea close to low tide were wind-generated. That was that for the bike tour — now I had to take pictures. Below […]

The wonders of a Wadden Sea. Or what someone addicted to #wavewatching thinks they are

mglessmer — Tue, 07 May 2019 13:05:39 +0000

As someone living on the German Baltic Sea coast, I don’t spend a lot of time on the North Sea coast (except, actually, my week-long vacation after Easter with my godson and his family, and when my friend Frauke and I went to Sylt earlier this year, or when Frauke and I are going back […]

Influence of wind and water depth on a wave field (or: a beach vacation in Dornumersiel)

mglessmer — Mon, 06 May 2019 13:05:42 +0000

I took the selfie above mainly to send to my mom from my vacation in Dornumersiel on the German North Sea coast. But then when looking through the hundreds of pictures I took that day, I realized that not only was my hair parted on the wrong side because it was so windy (ha!), the […]

Wave watching from a train

mglessmer — Wed, 06 Mar 2019 05:09:25 +0000

You know how they say that the journey is the destination? That was certainly the case for my spontaneous mini-vacation yesterday (and how awesome is it that my #BestTravelBuddy is up for a cross country trip on a day’s notice?). We went all the way from the east coast to the west coast — which […]

And we are wave watching again! A ship’s wake and the different zones within Here is the wake of the little ferry that goes across Kiel canal. I love how you can see the different parts that a wake consists of: The V with the ship at its tip that consists of wavelets from the […]
