Can anybody do the math on the wind chill at 155mph and 12 degrees?

Loose calculation here: (12 degrees F-32)/1.8 = -11 C * 155 mph wind = freakin cold!

It's actually -25. According to NOAA, Wind speeds above 40 mph have little additional chilling affect.
I would think that if I was not rolling like tumbleweed across the snowfield, I would get a pretty good wind burn or sandblasting of pellets.
Nice picture Fresh!

I spent some time looking through the archived NWAC data today. As far as I can find, the 155 mph gust is the highest wind speed recorded at Camp Muir since that site was installed in September 2006, and also the highest wind recorded at any NWAC site over the full period of data. The previous highest was recorded at Mission Ridge, which reached 137 mph in January 2007 ( see this old thread for discussion on that event and previous Mission Ridge winds over 100 mph).
A list of days with winds over 100 mph at the Muir telemetry site:
[tt]
06Sep2006: Muir station installed
06Nov2006: 121 mph (16" of rain in 48 hrs at Paradise, park flooded and closed until May)
29Apr2007: 125 mph
30Apr2007: 100 mph
12Nov2007: 119 mph
26Nov2007: 117 mph
02Dec2007: 111 mph
29Feb2008: 109 mph
03Mar2008: 100 mph
23Mar2008: 131 mph (avg 109 mph)
data missing for most of Oct-Nov-Dec 2008
27Jan2009: 110 mph
07Mar2009: 108 mph
15Mar2009: 126 mph
04May2009: 113 mph
17Oct2009: 106 mph
11Mar2010: 101 mph
20Mar2010: 106 mph
28Mar2010: 100 mph
19May2010: 113 mph
15Nov2010: 111 mph
12Jan2011: 109 mph
07Feb2011: 116 mph
11Feb2011: 109 mph
12Feb2011: 155 mph (avg 132 mph, min 107 mph)
[/tt]
There are large amounts of missing wind data at Muir, often for days or weeks at a time, due to the anemometer riming up and freezing solid, and also due to occasional communications problems. Nevertheless, the February 11-12 wind event is clearly exceptional in both magnitude and duration, far beyond any previous storm recorded in the data. Maximum gusts over 100 mph for 27 consecutive hours, average winds over 100 mph for 12 consecutive hours, and sustained winds never dropping below 105 mph for the 2 hour peak.

you have any idea the specs on the specific instrument the NWAC uses for this station? in 150+ mph within its calibrated ability? i guess aka, how reliable are the numbers even before it breaks 3 digits?
good stuff though, would love to see some footage up there from 2 12 1500!
