Expand The DGZ is the temp range where you get max dendritic crystal growth...that -12C to -18C layer. The snow crystals will grow in varying arrangements and size at any sufficient temperature/supersaturation below freezing though. "Sufficient" meaning cold enough to produce ice nuclei. That sounding kinda sucks for snow growth because the entire max DGZ is below the ground. Where you have saturation and lift the temps are in the -30s Celcius. That's going to give you small crystals in the shape of prisms, columns, and bullets...i.e. lower ratio and sugar like. Link to comment Share on other sites More sharing options...

weathafella Posted December 30, 2017 Author Share Posted December 30, 2017 Walk right in by the rooftop singers climbed the charts to number 1. I was excited about the cold. The original uncle wethbee was talking about the big vortex in eastern Canada. I was hoping for snow but alas-no soap. The following late December was also kind of cold. I had a date NYE and I remember walking across town with snow squeaking under my feet. A lot of cold December’s in the late 50s to mid 70s.
