High humidity rules in the predawn hours of a cool winter night, as a blend of radiation and advection fog envelops the expansive asphalt slabs that serve automotive commuters to the National Weather Center. Norman OK (13 Feb 10) Looking E 35.1822, -97.4397 … [Read more...]
Wall Cloud and Wildflowers
Treat yourself to mesocyclonic eye candy, courtesy of a midafternoon supercell which formed near Anton, NW of Lubbock. There's nothing quite like a wall cloud and wildflowers to complement any story of the Great Plains! Note the low-hanging tail cloud extending NNE (rightward), from the wall cloud to the top of the rain foot produced by the intense core at right. Rain-cooled air was being drawn … [Read more...]
Altocumulus Undulatus
Classical undulating altocumuli sweep high above the Nebraska Panhandle. This set of undulatus was not as laminar as many, and might be considered a hybrid with castellanus because of the distinct convective elements riding atop some of the bands. Although we were on the way from a great South Dakota chase the day before to a date of destiny with some Kansas tornadoes the next day, the striking … [Read more...]

From the cyclonically violent to the gentle and serene, the atmosphere presents endless ways to captivate the alert and … [Read more...]
Stalactite Attack

Amidst them sits a bottle-shaped stalagmite that has grown into the ceiling. 4 W Whites City NM (9 Jun 14) … [Read more...]
Blue Hole of Haukadalur
As with similar hot-spring pools in Yellowstone geothermal areas, heat-loving micro-organisms accentuate the natural blue hue of the mineral water, which is too torrid for human touch. Such a stark and strange scene conveys the rawness of this Earth before human habitation, or perhaps, after the last of us is extinguished. Haukadalsvegur, Iceland (11 Aug 14) Looking SE 64.3138, -20.3016 … [Read more...]
