We had driven down from the north and turned east, ahead of a supercell with a long-lived tornado that was reported to be crossing I-40 near El Reno. From a position SW of Piedmont, we waited patiently for its approach. A somewhat rain-wrapped tornado pair gradually became visible immersed inside the hazy murk to our southwest, merging, then expanding quickly into a dust-flinging barrel shape, … [Read more...]
The Stacks of Reynisdrangar
Volcanic crags stubbornly stand after millennia of ferocious beatings from the far North Atlantic's icy gales and subpolar surf. This day, however, the erosive forces relaxed. A million twinkling diamonds surrounded the sea stacks, silhouetted before a distant stratus deck, rendering their temperament at once placid and ominous. Still, the old maxim, "Never turn your back to the sea," is wise … [Read more...]
Lightning on Cheyenne Ridge
We thought the storm-observing day was nearly over after exiting the backside of an outflow-dominant complex of storms and marveling at its sunset mammatus display. Instead, in the southwestern half of the sky, crackles of distant thunder appeared from an intensifying left-moving storm moving generally in our direction, while an occasional, tall stroke split the air beneath. All around, the … [Read more...]
Optical Glory
One of the best ways to see a glory is from an aircraft overflying liquid-water clouds. Sunlight is backscattered toward the sun by uniformly sized cloud droplets, in a process loosely akin to the visualization of a rainbow (but with far smaller water particles). When observing a true glory, your eyes always will lie on a straight line between its middle and the sun behind you. Put another way: … [Read more...]
Bigger than Bicentennial
One smooth but decidedly severe hailstone lies atop a fencepost, compared to a celebratory coin milled 34 years earlier. Conveniently, a quarter is an inch across; so this hail reached two inches in diameter, qualifying it as "significant" by conventional definition. Hailstones actually should be measured precisely with a ruler or calipers when reporting maximum diameter to the National Weather … [Read more...]
Wall off Saga Bay Apartments
The most intense portions of Andrew's eyewall passed over this spot, stripping a poorly attached exterior wall off an apartment building in the Saga Bay development northeast of Homestead. [This was close to Burger King corporate headquarters, where Andrew's 16.9 foot storm tide is a South Florida record.] After the hurricane, some residents of this building salvaged their belongings by lowering … [Read more...]
