How Cold Is It?published Jan 6, 2014
Those who regularly exercise their QR state of mind routinely find themselves asking, "Compared to what?" So, as I look out my window at daytime temps of -20o F (we're headed to a high of -15o F from a low below -20o F) I thought I would take on this important question.
- While Ohare Airport posted a record, meaning they haven't been this cold at this time of year in over 100 years, in Minnesota our -20o F won't even come near the coldest 10 observations. (You have to get to -33o F to make that list.)
- The South Pole clocked in at -11o F this morning. We could send them "Wish we were there!" postcards.
- Today's predicted windchills of -40o F to -50o F–or even the alarmist warnings of -60o F–won't top (or bottom?) the 1936 Twin Cities record of -67o F'.] Note: Prior to 2001 we reported that as -87o F, but then we figured out that the formula for calculating the effects of wind speed on perceived temperature were overly aggressive. We don't want to exaggerate! It was only -67o F!
- The [link http://usatoday30.usatoday.com/weather/resources/askjack/wasnow.htm 'average low temperature at the US South Pole Station during the months of July-September is -81o F. At that temperature, even a breeze of 10 mph creates a windchill below -100o F.
All in all, I feel better about my lot when it is put in perspective. Another advantage of QR literacy!
