Piteraq - The Greenland katabatic wind
« on: November 15, 2016, 11:54:52 PM »
The Piteraq originates on the Greenlandic icecap and sweeps down the east coast. The word "piteraq" means "that which attacks you".

Currently one running down the east coast today.

At 18Z today the station at Ikermit had gusts to almost 193 km/hr (coupled with an air temp of -6.4  :o )

Interestingly "wind chill" calculators equate that situation with about -25C with no wind, which must be totally incorrect! The catabatic wind in question would kill a naked person extremely quickly, while hanging around in -25C with no wind at all is not that dangerous (I've spent 3 minutes in -110C with no real problems at all).

Extremely strange.
btw, is the 110oC correct, or a typo??
