-45 degrees F in October in Utah...wondering....

Post by wbdeford » Wed Oct 30, 2019 9:49 pm

It was -45F this morning in Peter Sinks, Utah....about a 1/2 mile away and about 300 ft higher, it was about -4F. The terrain allows this huge difference at night in calm winds. This got me to wondering.....

Does DVNP have any areas where this sort of thing could occur--a large temp difference within a short distance and not much elevation change?

Good catch Brian, wondering if true but in the opposite temperature direction of heat. One would assume Badwater is always the hottest, but maybe there is a "sink" somewhere with higher temps?

I have experienced inversion layers in the park several times; most often in the winter after storms. It'll be in the 50s in the valley but also up at Wildrose. I've never seen or heard about a 40 degree difference though, however we do have those in Oregon (ice in Portland, 45 and sunny at Mount Hood).

It just occurred to me that an obvious place to check for this sort of thing would be Ubehebe Crater. It has a similar depth to Peter Sinks (a little deeper)....dry climate....only thing it lacks is high elevation. Would be interesting to compare the rim and the bottom on a cold, clear, calm morning.

Latest data point at Peter Sinks, is 5 degrees on the rim and -44 at the bottom.
