A beautiful day in La Fouly (Switzerland)
During a sensor maintenance and data collecting session with some members of the EFLUM Laboratory (EPFL, Switzerland) we were lucky to observe impressives Kelvin-Helmoltz Breaking Wave Clouds over the top of the mountains. This spectacular behavior of the air occurs when there is a velocity shear in a single continuous fluid. In this particular case, the Kelvin-Helmoltz waves were followed by a zone of the mountain that was directly exposed to the sun which explains the diffusion of the clouds on the left of the picture.
My name is Raphaël Hoesli and I have a strong passion for photography. I am based in Bienne in Switzerland. I began photography at the age of 13 with my father's Canon AE1 camera. First attracted by Wildlife and nature photography, I progressively started with sport, events, city and people photography. This website should provide a good general idea of what I do.
