  • Double Reflected Convective Pastels

  • A weakening supercell moved over cool outflow from earlier storms, combining with some fall foliage at ground level to dazzle who witnessed the spectacle with a brief but brilliant splash of pastel tones.  The dominant light source for the scene came from a strange direction, too:  northeast (left)!  Sunset light first was r[...]
  • Upstream from Angel's Landing

  • To arrive here, one must hike a series of switchbacks adding up to 2.5 miles and 1500 vertical feet each way from the Virgin River, or a total of 5 miles and 3,000 vertical feet.  Parts of the hike ain't easy, traversing slick, tilted, sand-covered rock slopes bracketed by thousand-foot dropoffs within just a few feet distan[...]
  • A Peculiar Experience

  • 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[...]
  • Doppler Ray-dar

  • In the early–mid 1990s, the National Weather Service, in word and deed, established the WSR-88D (a Doppler radar) as its own "ray of hope".  This shot, therefore, would be ideal for a promotional brochure touting its marvelous powers.  Actually, the radar dome located on OU's North Campus was fortuitously juxtaposed in this [...]
  • Towering Cumulus and High Country Foliage

  • At 9,000 feet high in the Colorado mountains, deep convective clouds and brilliantly peaking fall aspens are an uncommon combination to witness.  Still, the passing of a mid-upper level trough over seasonally warm and moist conditions for the area produced this outstanding high-country vista—a summertime sky over a decidedly[...]
  • Convective Tower Shadowing Smoke

  • Towering cumulus created a strange and eerily beautiful visual effect, shadowing boundary-layer smoke that had wafted 125 miles from the Cow Camp fire in Wyoming. That 6,000-acre blaze started a few days earlier in the Medicine Bow National Forest NW of Wheatland WY, and sent pulses of dense smoke skyward. Southwesterlies be[...]
  • TCu (not TCU)

  • A classical towering cumulus (meteorological acronym: TCu, as opposed to TCU the university) shoots skyward in a low-level convergence zone connecting other, larger areas of convection.  Storm observers who can see through towers don't assign them much of a future, and for good reason; they are entraining dry air aloft.   St[...]
