We had an upslope storm come and go here in Colorado. It left solid phase hydroxylic acid all over the place. Fortunately, my Jeep has a special traction setting for that situation.
State officials have attempted to deal with it by using Group 1 and Group 2 metal halides as well as diaminocarbonyl to affect the colligative properties of the hydroxylic acid crystals. This leads to an increase in the friction coefficient of the asphaltene and hydrated calcium oxide conglomerates used by motorists.
Lamentations on Chemistry 
And you didn’t even mention associate any thixotropic properties with these materials! That made my day.
Hi John, I’m frightened away from the subject for fear of riling the Rheovolken out there.
The EPA goes ballistic ove a few ppb of this and that but utterly ignores a three foot depth of solids deposition. A sternly worded public petition to FEMA is in order. You are VICTIMS!
Does all the white crap affect your wind generators, algae ponds, cornfields, solar farms, and other sources of Earth-saving alternative energies?
Around here we only use Group II halides, and prefer to eschew obfuscation.
How does the snow go upslope? I don’t live in a place with actual slopes.
Brilliant.
Hap- When a moving, humid air mass follows the terrain to a sufficiently high altitude, it cools to the dew point and clouds can form. If there is enough moisture in the air, precipitation will occur. If it is cool enough at altitude, the precip will be snow. The snow can melt on the way down bringing rain to the lower elevations and snow to the higher elevations. In the winter it is cold enough in the eastern half of Colorado to crash out most of the moisture as snow.
Upslopes work best in Colorado if there is a low pressure system over the OK/TX Pan Handles rotating counter clockwise and moving moist gulf air. High pressure rotating over SD will cause the effect as well. But the Whopper storms that shut down civilization from NM thru CO to WY and KS is when there is a high pressure system over SD and a low pressure system over the TX panhandle. The two pressure systems work synergystically to lift a lot of air uphill and coat the western midwest with a good bit of snow.
It is not uncommon for an upslope snow storm to paralyze the flat lands right up to the mountains, but leave the mountains untouched by snow.
A kind of opposite situation is the Foehn or Chinook wind scenario. Moist air coming from the Pacific flows in an easterly direction uphill, dumping snow as far east as the continental divide. The combination of compressive heating and release of the latent heat from snow formation causes the easterly winds to warm dramatically by the time they get to the flatlands (i.e., Denver). This is a winter phenomenon mostly. Foehn winds are often quite warm, subliming the snow, but howling at high speeds.
I call for a complete ban on hydroxylic acid use. It’s high time someone make a stand!
Mercury, lead, hydroxylic acid (the liquid stuff is the worst!). I will call the EPA and threaten to eat six ounces of the solid crystalline stuff on the steps of their building if something is not done!
You know what that will do to me?
Brain freeze?
Sorry. For some reason I had a mental picture of a snow storm moving east to west up the mountains and snowing at lower altitudes and that didn’t make sense to me. Thanks.
