One of the most amazing sunsets I (still!) have witnessed wasn't just the astoundingly brilliant display of light and clouds and the northwest, but the rest of the sky too. At a right angle to the left of the supercellular mammatus, the southwestern sky also blazed brightly, on and all around a fast-growing young dryline cumulonimbus that didn't exist visibly just a few minutes before. Thirteen … [Read more...]
Autumnal Altocumulus Translucidus Undulatus
On a fine and cool fall morning, it was a treat to round the corner of Battlestar Norman and see this splendid field of altocumulus translucidus undulatus covering a substantial proportion of the northern and eastern sky. This came nearly a month after a wonderful sunset display of silhouetted undulatus clouds as seen from these grounds, and brought to mind a different but equally beautiful … [Read more...]
High-Based Wall Cloud and Forward-Flank Core
Though high-based, with only weak visible rotation, this supercell had a large updraft, visible from many miles away, and deserved closer scrutiny. A quick jaunt NNW out of Roll provided such an opportunity, albeit short-lived. Focal length here was 50 mm, shooting 35-mm Ektachrome slides; so yes, it was close, but not dangerously so. After dropping back south to get out of the way of both the … [Read more...]
Window Dressing
Consequences of forgetting my usual vehicular tarp in a night-shift freezing-rain event included this one, for which I'm now glad, thanks to the incidentally abstract artistry. All that was necessary was to heat up the interior for a few minutes and roll down the window partly, with no significant frictional resistance, thanks to a thin melting layer that formed on the inside of the ice. Once … [Read more...]
Blast in the Dark
Numerous lightning flashes punctuated the sky in the middle to far distance on this eventful evening, most of which illuminated some cloud material or thin shafts of anvil precip between us and the main storm core. I probably shot two dozen slides of those strikes, mostly of dissatisfying quality due to either distance, or the lack of any evidence of foreground, given the utter dearth of … [Read more...]
Colorful Mare’s Tails
On this day after a deeply disputed election, chaos, uncertainty and sociopolitical tumult precipitated in the news all around. I welcomed and preferred this form of precipitation instead: long thick streamers of snow virga in the upper troposphere, falling from cirrus clouds into brilliant sunset light, forming uncinus, long known as "mare's tails". Norman OK (4 Nov 20) Looking S … [Read more...]
