Yellowstone Morning Fogs

By

On a cold Yellowstone dawn, two fog sources blended to form an enchantingly eerie and ethereal scene: ground fog from the previous day's heavy rains and condensed steam risen out of geothermal vents.  For about an hour, an area of several square miles around the park's western geyser basins resembled a giant version of the stages and fun houses that use dry ice to create chaotically dancing and … [Read more...]

It’s BeHIND You!

By

Driving southward past the west side of a supercell, out in the rain-free area just behind the storm, we were hearing tornado reports but couldn't see it buried in the storm's murky precipitation shield to our left.  While crossing a creek valley, this—the dying tail end of the tornado being reported—emerged back to our northeast, off port stern.  The snakelike funnel had quickly popped out of the … [Read more...]

Last-Gasp Circulation

By

A tail cloud, clear slot and ragged area of rotation marked the final wall cloud of the last in series of supercells we would intercept on this day. The old, deeply occluded mesocyclone responsible for this wall cloud seemed to be running on fumes, with cool air in its inflow region. Among other events of years past, we learned from a photogenic tornado a couple of hours before not to dismiss … [Read more...]

Steam in the Fog

By

It seems post-apocalyptic:  this heat-blasted landscape of conifer skeletons, rising steam, bare and mineralized ground, in a sunrise light that reminds of artists' conceptions depicting primordial planets.   Yet the scene is readily available in some form, on most cool mornings in the Lower Geyser Basin.   Locally heavy rains the day before had left the ground saturated also, contributing to an … [Read more...]

A Peculiar Experience

By

Almost immediately behind a powerful complex of thunderstorms, enough instability remained above the cool, moist, somewhat hazy outflow air near the surface to generate still more deep convection.  One can tell that this towering cumulus clump is somewhat starved for buoyancy by its soft, translucent appearance, and the hole almost directly centered on the cloud mass.  We were too bedazzled by the … [Read more...]

Genoa Spin

By

A two-dimensional image doesn't begin to convey the intense, furious rotation that was going on in this wall cloud.  The formation, hovering over Interstate 70 in eastern Colorado, spun so fast that I thought it would produce a big tornado anytime.  This was shot wide-angle; so we were rather close to the action.  At least as fascinating as the rapid motions, I found that the menacing black base … [Read more...]
