SUMMARY

The coldest place on Earth is the East Antarctic Plateau, as confirmed by the National Snow and Ice Data Center after analyzing 32 years of satellite data. The lowest recorded temperature reached an astonishing minus 136° F (minus 93.2° C) on August 10, 2010, in pockets near a ridge from Dome Arugs to Dome Fuji. This extreme cold is attributed to stationary air that radiates heat away into space. In contrast, the coldest permanently inhabited location is in northeast Siberia, where temperatures have dropped to minus 90° F (minus 67.8° C) in towns like Verkhoyansk and Oimekon.

What’s the coldest spot on Earth? NASA has pinpointed it — and the nights are deadly​

https://www.yahoo.com/news/coldest-spot-earth-nasa-pinpointed-125903009.html

The National Snow and Ice Data Center concluded the East Antarctic Plateau was the coldest place in the world after analyzing 32 years of data from several satellites, NASA says. The hollows on the plateau are considered the coldest spots.

“Near a high ridge that runs from Dome Arugs to Dome Fuji, the scientists found clusters of pockets that have plummeted to record low temperatures dozens of times,” officials reported. “The lowest temperature the satellites detected - minus 136° F (minus 93.2° C), on Aug. 10, 2010.”

Scientists attribute the plateau’s dangerous temperatures to a combination of air that is “stationary for extended periods, while continuing to radiate more heat away into space.”

However, the plateau is not “the coldest permanently inhabited place on Earth,” experts say. That’s located in northeast Siberia, “where temperatures dropped to a bone-chilling 90 degrees below zero F (minus 67.8° C) in the towns of Verkhoyansk (in 1892) and Oimekon (in 1933).”

Isn't that lower than the sublimation temperature for CO2 at atmospheric pressure? (−78.5 °C)

Do they get dry ice snow on that Plateau?

Think about it....
 
"Carbon dioxide freezes at -78.5 degrees Celsius or -109.3 degrees Fahrenheit under atmospheric pressures. The coldest (we know) it has reached in Antarctica is about -93 degrees C. However, dry ice will not form there. This is because it has a very low abundance in the earth's atmosphere, about 0.04% by volume"

And when you add in wind chill, that's pretty cold... :oldbiggrin:
If you have any brass monkeys, better put 'em in a warm spot.

Although there is no wind at really cold temperatures, forget the reason, but its also the case in Yakutia in Siberia where temps get below -60C
