Low ‘Bow

By

What this rainbow lacked in height, it made up in stunning clarity and brilliance, made possible by the combination of strong direct sunshine, dark-storm background, and clean air on the back side of a scuddy, outflow-dominant, post cold-frontal supercell.  Every primary rainbow's outer red ring would be a full circle spanning 42 degrees of view, centered exactly opposite the sun, if the Earth's … [Read more...]

Charged Atmosphere in the Borderlands

By

In the short distance between Tucson and the Sonoran border at Nogales, the atmosphere on this day was seriously charged up, and it manifest marvelously  as cloud-to-ground lightning.   Storms that fired in early afternoon on the Santa Rita Mountains to the east lingered there for a few hours before sending outflow across the I-19 corridor to the west, which in turn set off this convection.  Other … [Read more...]

Electrical Lacework

By

As a severe thunderstorm complex moved away, it continued flinging cloud-to-ground lightning, mostly less-forked than earlier, while increasing its delivery of "crawler" discharges within the trailing precipitation region.  The delicate and intricate appearance of these filaments belies their deadliness, should one be unfortunate enough to sample any of the electricity directly.  At distance, … [Read more...]

Sterling Sunset in the Desert

By

Even though the thunderstorms that produced the brilliantly lit, anvil cirrus clouds dissipated before I could get any decent lightning shots, this sunset scene was a wonderful consolation prize.  Light on the lower cumulus and fractus clouds had to travel through more of our atmosphere to get there, and therefore is redder.  The variation between low and high clouds, in both light and texture, … [Read more...]

Dark Turbulent Arcus Base

By

The day's outflow-dominant storm intercept finished, we rolled south, the hunters now the hunted, cruising at barely legal speeds on the interstate highway to stay ahead of the core.  As we surfed the cold outflow winds, we remained for a long time beneath the "whale's mouth" of an uncommonly beautiful, well-defined, slate-blue underbelly of the arcus cloud.  The striking coloration may have been … [Read more...]

CG behind Arcus

By

While taking a short break from escaping this raging squall, we stopped to admire and photograph its tiered shelf cloud and arcus formation with a windmill-punctuated wheat field in the foreground.  This was the rare shot where the lightning serendipitously struck as I happened to click the shutter, though I had been attempting unsuccessfully to capture a few other strokes manually.  We soon would … [Read more...]
