- International Women’s Day: Unsilencing the Forgotten Pillars of MeteorologyIn the pages of scientific history, one often hears too much silence. A science–especially meteorology–is built by women who are rarely, if ever, remembered, let alone credited.

- Flying the Fastest SkiesHow fast can an airliner go? Monday night a Virgin Atlantic Boeing 787-9 reached 801 m.p.h. en route from Los Angeles to London. Matthew Cappucci of the Washington Post reported the jet reached this amazing speed—a record for the Boeing 787-9 and probably the highest speed for a non-supersonic commercial flight—while cruising at 35,000 feet over the central Pennsylvania. Clearly the plane was hurled along by an […]
- New Western Storms Scale to Describe Intensity, Potential Impacts of Atmospheric RiversHurricanes are classified by the Saffir-Simpson Scale and tornadoes by the Enhanced Fujita Scale, and now atmospheric rivers—those long, transient corridors of water vapor that fuel flooding rain events each winter in the West, especially California—will also be scaled to enhance awareness and bolster prediction. The new AR scale ranks their intensity and potential impacts […]
- Making Sure No Tornado Damage Is Too SmallPlanetary, synoptic, meso-alpha, meso-beta, local, and more—there are atmospheric scales aplenty discussed at AMS meetings. Enter microtopography, a once-rare word increasingly appearing in the mix in research (for example, here and here). The word is also coming up as researchers are getting new tools to examine the interaction of tornadoes with their immediate surroundings. Microtopography looks like a potential factor in tornadic damage […]
