News from the Arctic: 21 November 2010

by billlaurelMD

This is the next in a series of diaries on the state of Arctic sea ice (and other topics as warranted) in memory of Johnny Rook, who passed away in early 2009. He was the author of the Climaticide Chronicles.

This diary will be relatively short; not the Climate Change News Digest, but just news from the Arctic last week.  Headlines:

  • Ice extent increased more slowly than usual last week.
  • The general circulation set up in something like what's called a positive Arctic Oscillation, with stronger-than-normal cyclonic circulation at high latitudes, and higher than normal pressures toward the south.
  • Sea ice extent is less than it was after the record melt of 2007.

Here's a picture of the scene from the Barrow AK Arctic sea ice web camera taken last weekend.
