Using NOAA snow/ ice cover

For earlier materials see Table of Contents

Arctic Freezing	Seasonal ‘progress’
	Images from NOAA snow cover

Arctic remains warm – clear water above -----------Compare the snow cover 20^th to 11^th

Again, as seen last year (where done 2 weeks later in season)

· Increased snow cover

· Beaufort Sea etc freezing over

Interesting – differences become less obvious when Nov 11^th compared than 20 Oct

Watching the ice freeze

On 24^th October waters around Boothia Peninsula (red arrow) beginning to freeze

And by 28^th the ‘NW Passage’ almost closed (red arrow)

--	What a difference a day makes
	Note the snow fall in BC when November 3^rd compared with November 4^th

Snow Cover

By the 11^th BC was losing snow cover (red arrow). Rains?

While in Alaska the Anchorage/ Kenai Peninsula area (blue arrow) going into deep freeze for winter

	Comparing different years
	Given the archives on the NOAA snow site – I compared series 2004 through 2007 – both for my start date of October 20^th and my end date of November 11^th ---- while each series is similar --- I argue 2007 was the warmest of series --- though becomes less dramatic for the 11 November series
