Seeing Kelvin Helmholtz
24th January 2017
A milder day but with cooling winds, snow fields still available on North-East to East aspects.
We also had along with us today some of the mountain weather forecast team from Met Office Aberdeen. On a regular basis we get together and discuss weather effects on snowpack stability as well as continuing our collaboration and discussing ways to improve information exchange and forecast provision to mountain and hill goers. It was good that they were along as we were able to identify a very rare Kelvin Helmholz cloud, an indicator of wind shear, with strong winds above the cloud plucking cloud strands from its upper surface into a unique and fleeting fishbone like shape.
