#WaveWatching: Wind & sheltering

For my dear friends, who are worrying because I didn’t post any #WaveWatching pics recently: I’m still here, and I’m still wave watching! :)

For example on my lunch time walk with F today: Isn’t this a beautiful pic of how waves build up over both time and distance if the wind is blowing continuously? In the far back, there are hardly any waves because the water is sheltered from the wind, and the water looks dark, because it’s reflecting the trees in the back. As we move away from the trees and onto the open lake, waves grow. We now see the sky reflected in the rougher parts, but in other parts we still see flat areas where there are smaller waves and we notice the reflection of the sky.

The closer we move to the foreground, i.e. downwind, the larger the waves become. Until there are pieces of wood floating in the water that suddenly shelter a small area! Notice how suddenly there are only “longer” waves moving into that area, but all smaller wavelengths disappear, because the wind forcing is gone?
