Some more memories from my September mountain trip and mountain boundary layer: clouds filling the valley and climbing up toward us

Here the teaser movie...see later more for explanation

Last week at the Italy–France border: moist valley air rising and forming near-surface clouds, while a higher cloud layer (with a cloud base of around 3,500 metres) tries to grow by convection, but fails to reach the rain stage. Beautiful!

lots of shallow convective weather for me recently

And the @bokuvienna.bsky.social radar capturing it met.boku.ac.at/wetter/radar...

Nice one just over NW Vienna, from 10 min ago #Wien #Wetter @uwz.bsky.social

While preparing for teaching on deep convection tomorrow...I managed to capture this nice shelf cloud approaching NW Vienna; see also how clouds at different altitudes travel in different directions => wind shear
