Rivulets of water, ranging in temperature from frigid to scalding, pour down a gravelly hillside in one of Iceland's largest and most peculiar geothermal fields, forming a fluidly abstract landscape of undular texture and strange tones. Behind such alien beauty often lurks hidden danger, and this area certainly qualifies. Some of the island's most notorious eruptions (including Krafla, which is … [Read more...]
Dragging a Dust Plume
After the brief but scenic Phillips tornado had spun its way north of the highway and dissipated, a second tornado developed from the same mesocyclone. At first, this one similarly left a long gap between condensation funnel and small debris cloud. That soon changed in a major way as it got closer. In the meantime, however, a dense plume of non-rotating dust rose off nearby plowed fields south … [Read more...]
Panhandle Power
After peaking in width, the Canadian (TX) tornado gradually narrowed but still presented a stout appearance at this stage. Tornado size does not necessarily offer any insight into intensity. In fact, assuming the mass flux through the vortex changes little or none, a tornado can strengthen as it narrows, due to conservation of angular momentum. Because this tornado occurred mostly over scrubby, … [Read more...]

The chorus of thousands of frogs … [Read more...]
Brule Blow

Shortly after sunset, the marvelous pastels of twilight emerged above and along the formation. This manner of subtle yet somewhat surreal front-lighting is why early twilight is one of my favorite … [Read more...]
Big Bend Discharge
Late May usually is a hot time down in Big Bend country, but an active southern-stream pattern that flooded much of the southern Plains kept the southwest Texas deserts well-soaked also. The back side of one of the responsible storm clusters sliced the sky with this lightning bolt, after its other end ran us off the Rio Grande. 26 ESE Terlingua TX (21 May 15) Looking S 29.2651, … [Read more...]
