Now notice a couple of things - the type of crystals they're creating in the lab sure sounds like
but the conditions they create are somewhat different than the conditions NAC describe on their page.
cold sunny calm day (followed by storm)
clear + humid calm day, forms in the shade (followed by storm)
So...do the primary driving factors for surface hoar vary by location (one thing in Montana, another in California, frex?) Or is the movie actually talking about faceted snow, the sun creating a gradient > 1C per 10cm?
If #2 - then does faceted snow "fill in" the sunny zones where surface hoar didn't occur?
