Boiling volcanic mud in the Hverir geothermal area paints a wondrous abstraction of concentric bands and contours, shifting and distorting with each new upwelling, evoking a fluid topographic map or a shape-shifting field of scientific isopleths. 3 E Skutustadahreppur, Iceland (22 Aug 14) Looking ESE 65.6417, -16.8098 … [Read more...]
Sailing off Key West
The soothing salve of a Florida Keys seaside twilight was almost too calming! I had to shake free of the mellow mood just long enough to scramble to the tripod to compose this shot, in the precious few seconds after realizing these boats were about to line up so perfectly. Thus resulted one of my very favorite images of 2009. Right place, right time... Key West FL (5 Jan 9) Looking … [Read more...]
Flash in the Forward Flank
A brilliant cloud-to-ground stroke illuminated the forward-flank region of a classic nighttime supercell, just about the same time as the Anadarko tornado began to move into town, unseen to our west. In fact, being a wide-angle view, this flash was much closer than it looks; in-cloud lightning raced across the sky overhead, and the storm as a whole was closing in. We packed our gear to leave … [Read more...]
Electric Wrap
Not often do I manage to catch one of these fast little middle–upper-level lightning filaments during the daytime, without a time exposure, but I got lucky here. Convective plumes running up the back of a tail-end Charlie supercell hosted all manner of flickers and flashes, this one wrapping outside and around one tower like a sparky gift ribbon. I definitely appreciated the atmosphere's … [Read more...]
Millsap Supercell 2
The Millsap supercell organized even further, tightening its rotation at all levels while forming two wall clouds with two occlusions in rapid sequence. Here, the decayed remains of the older wall cloud can be seen in the middle, while at slightly nearer right, a bigger and lower one protrudes, soon to wrap in rain, become tornadic, and unwrap again. Looking at the big picture (literally!) the … [Read more...]
Millsap Supercell 1
A robustly structured supercell looms over one of America's main transportation arteries: Interstate 20, west of Dallas. In this area, rugged lowland terrain covered by scrub forest makes storm observing hard; a combination of high spots and openings is needed. This hilltop, conveniently coinciding with the Brock exit and a construction-zone staging area, was good in a pinch. The storm itself … [Read more...]
