We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Sublimation is the process by which a solid goes directly to a vapor. Snow does that, even when it's below freezing. It evaporates. It's finally above freezing during the daytime here, at least for a day or two.
My grandfather used that expression--or was it 'poor man's manure"?? Anyway, ever notice how green the grass looks after a spring snow melts? As far as crops doing better after a snowy winter I think it's because things really stay dormant until they're ready, not starting to sprout and then getting refrozen by intermittant thawing.
The opposite of sublimation is also true - as the temperature drops in a humid air mass, the capacity to carry moisture also drops, and water freezes and precipitates. Working on the Asian Steppe many years ago, it was not uncommon to see a light, fine snow falling on a perfectly cloudless, sunny day, blue sky and all.
