Mesocyclone

I adored Camille Seaman's Last Iceberg photographs, and her new series The Big Cloud is just as stunning. She hunted the weather in search of supercells, a type of thunderstorm that (so Wikipedia tells me) is "overall least common and [has] the potential to be the most severe." I can't imagine being calm enough to set up my camera equipment and take such beautiful photographs with clouds like the ones she photographed roaring down on me.
