I'm learning nue wurds...

Many of you already know these words, and maybe I've heard them before but don't remember. (Life is such an adventure when you have the memory of an Alzheimer's patient.)

A colloquialism for a combination of snow and dirt/street litter usually found in urban areas or along the sides of roads.

A colloquialism for a combination of snow and dog feces usually found in urban areas.

And here's some that I've known but many of you maybe haven't...

Precipitation formed when freezing fog condenses on a snowflake, forming a ball of rime ice. Also known as snow pellets.
I'm often pelted by graupel above treeline.

Rimed snow
Snow flakes that are partially or completely coated in tiny frozen water droplets called rime. Rime forms on a snow flake when it passes through a super-cooled cloud. One of the 4 classes of snow flakes.
This can only form as the temps drop from above freezing to below freezing in high humidity. Often it is formed as snow or rain drops from the sky, passing through temperature gradients. It's what tends to "flock" trees with crystals.

Snow which has been lying for at least a year but which has not yet consolidated into glacier ice. It is granular.

Snow formation found at high altitudes. They take the form of tall thin blades of hardened snow or ice closely spaced with the blades oriented towards the general direction of the sun.

Depressions in the snow caused by sun melting.
This is a layman's term referring to the spaces between small penitentes, but penitentes can become huge (as tall as a person).

Transition from the solid to gas phase with no intermediate liquid stage.
In other words, snow or ice can evaporate without melting. Much of our potential water-source is lost to sublimation. Sublimation is higher when trees are loaded with snow.

The removal of a substance from another surface. Ablation may refer to the melting of snow or ice, and then the evaporation or runoff of the water, or it may also, vaguely or from context, refer to sublimation.

Corn snow
Snow that has partly melted and refrozen and acts like ball-bearings

Sugar snow
Snow that has crystalized into granules and has the consistency of sugar. This tends to form under harder crusts of snow.
When wind-packed, hardened slabs of snow break loose, the sugar and/or corn snow underneath acts like a lubricant that lets the slab pick up amazing speeds during an avalanche.

Lemme guess, it finally decided to snow in Colorado.

I left you a funny retort on my blog comments.

Hope you're well!
