Needle ice forms when the temperature of wet earth is above freezing, but the air is dry and below freezing. The liquid water in the soil wicks to the surface via capillary action through small pores and cracks, where it freezes on contact with the cold air; it expands and forms a small ice cap atop the pore…

Meanwhile, in Northeast Alabama (really!)
The sirens were paid for with federal money, tested, but never turned on due to four noise complaints! Permalink: https://langa.com/?p=2704
Suuuure, the climate’s fine. No problems at all…
As if Boston’s warm-ish, nearly snowless winter wasn’t enough of a clue that something weird is going on, a local resident spotted a porpoise in Dorchester Bay last week — a normal event in Spring, not February. A brief Boston Globe article on the porpoise is here, and includes a phone video of something you…
Around Boston: The nearly snowless winter continues
Boston’s 2018-19 winter has been warmer and wetter than normal. There’s been some serious cold, but not too much; and a little snow and ice, but mostly liquid rain. It’s simultaneously convenient, and disturbing. Permalink: https://langa.com/?p=1966

Found! The missing “Part 5” to the tornado chase videos
Several days ago, I posted four videos of a tornado chase I went on a few years back. (For info and links, see A reader asks for reposts of my tornado chase videos.) That prompted another reader — Peter Wharton, who was in fact the driver of our van during the chase — to ask…
A reader asks for reposts of my tornado chase videos
Reader Drew Foster was hoping I could resurrect some videos from a tornado chase I went on in 2008, and he asked me about it via the Contact link: “Fred: Please re-upload your videos of the Quinter tornado. Part 2 is available on YT but that’s it.” Sure, Drew! In a week’s chasing from Texas…
