There are a few possibilities...all ...Interesting. There are a few possibilities...all of which are hypotheses or educated guesses. This is an interesting event because the temperatures are colder not on the valley floor, but near the base of the inversion (this morning, the coldest temperature in the sounding was at 5871 ft...coincidence, maybe not). The mixing ratio, which is a measure of the water vapor in the atmosphere, was highest just above this level. Thus, I suspect you are seeing the biggest facets at that magic level where it is cold, there is a high water vapor content, and you are in the upper part of the smog/haze layer so that the snow surface cools more radiatively. <br /><br />Below are the observations from this morning's sounding. Note that 5700 ft is just below 1790 m, very near the coldest temperatures and close to the higher mixing ratios.<br /><br />-----------------------------------------------------------------------------<br /> PRES HGHT TEMP DWPT RELH MIXR DRCT SKNT THTA THTE THTV<br /> hPa m C C % g/kg deg knot K K K <br />-----------------------------------------------------------------------------<br /> 1000.0 246 <br /> 925.0 859 <br /> 875.0 1289 -10.3 -12.0 87 1.75 110 4 273.1 278.1 273.4<br /> 873.0 1307 -10.3 -13.6 77 1.54 114 4 273.2 277.7 273.5<br /> 850.0 1515 -11.1 -12.5 89 1.73 160 2 274.5 279.5 274.8<br /> 820.0 1790 -12.1 -12.6 96 1.78 164 3 276.3 281.4 276.6<br /> 815.9 1829 -10.6 -11.0 97 2.03 165 3 278.3 284.2 278.6<br /> 814.0 1847 -9.9 -10.3 97 2.16 161 3 279.2 285.5 279.6<br /> 810.0 1885 -7.3 -8.5 91 2.50 153 3 282.4 289.6 282.8<br /> 801.0 1973 -2.3 -12.3 46 1.87 134 3 288.6 294.3 288.9<br /> 795.0 2033 -0.9 -15.9 31 1.40 121 4 290.7 295.1 290.9Jim Shttps://www.blogger.com/profile/15799757451626876963noreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-72649915290613870082013-01-07T11:06:33.614-07:002013-01-07T11:06:33.614-07:00Hi Jim, I have a random question.

I always assumed that the canyon bottom collected cold, moist air that faciliateted deposition. However, for the last few days I've been seeing big hoarfrost on the city creek ridgeline above 18th ave, at about 5700', with much smaller crystals down lower. What's up with that?Johnhttps://www.blogger.com/profile/14155124764305778798noreply@blogger.com
