From it one can learn that different temperature and moisture regimes can result in novel mixes of both ice crystals and supercooled water
droplets in the same air mass.
Snowflakes start with a mixed-phase layer containing supercooled water
and ice crystals.
A vivid example of the predictive capability of simulation approaches can be seen in the work on the detailed structure of ice embryos, where supercooled water
was shown to contain crystallized ice with sequences of hexagonal and cubic ice (Moore and Molinero 2011a).
It was a thing called graupel - a soft kind of hail which forms when microscopic snowflakes get covered in supercooled water
particles, which themselves then freeze to form these very soft balls of ice which people confuse with snow.
Freezing of supercooled water
drops on cold solid substrates: initiation and mechanism--Faryar Tavakoli, Stephen H.
Even homogenous nucleation of supercooled water
drops at -30[degrees]C has been reported.
That lends support to the idea, proposed by Stanley and colleagues 22 years ago, that supercooled water
undergoes a phase change at around -50[degrees]C into two never-before-observed liquid states.
We're solving a very old puzzle of what is going on in deeply supercooled water
Some supercooled water
may nucleate on particles in the water column or grow on small ice crystals scoured from surface sea ice, forming frazil ice.
Much discussion and experimentation traced the problem to one of the unique attributes of large ice shelves: supercooled water
Hail, for instance, happens when supercooled water
freezes on dust particles that are then pushed back into clouds via an updraft, over and over again, accumulating more water, and more size, until they finally crash onto our heads and cars.
The cloud phenomena is called a Fallstreak Hole caused by supercooled water
droplets freezing and falling away causing the hole to form in the sheet of cloud.
