May 10 2011. Wonderful dark wild skies set against a nice rape oil crop. The turbulent deck of stratocumulus cloud contains elements of a 'Whales Mouth' effect. This is caused by cooler air sinking from an adjacent precipitation storm/cell rolling along in the lower levels and undercutting warmer air thus pushing it aloft. The combination of sinking and rising of different airmass densities creates this effect. Wild and beautiful. Captured with Olympus E5 & 12-60mm SWD - 2 images stitched.
