[Part 1 of 2] This is the first of two images (from Provia slide film) of a single southwest Oklahoma supercell about 15 minutes apart. Here, two wall clouds can be seen: the one at middle rear beneath an older, occluded mesocyclone (that had produced a brief tornado while we were navigating through town, unable to photograph it), the newer one at nearer right, never tornadic, with less precipitation in front. A supercell is a localized but intense low pressure system, and because of that, the pressure forces make it breathe, quite violently sometimes! It continually inhales an enormous volume of air from many directions below and expels much of that air above, an atmospheric combination of a vacuum cleaner and a giant, tilted, rotating chimney.
