griteater Posted October 27, 2017 Share Posted October 27, 2017 On the current graphs, snow cover extent is right at one standard deviation above normal in each of the following areas: 1) Northern Hemisphere, 2) North America, and 3) Eurasia.

bkviking Posted October 30, 2017 Share Posted October 30, 2017 For what it is worth - latest SAI. Up there quite a bit. Link to comment Share on other sites More sharing options...
40/70 Benchmark Posted November 1, 2017 Share Posted November 1, 2017 I think the SAI is juiced as much as the baseball over the past few years. It seems like every season its through the roof. Link to comment Share on other sites More sharing options...

40/70 Benchmark Posted November 1, 2017 Share Posted November 1, 2017 So this year is the lowest it has been since 2013. Link to comment Share on other sites More sharing options...

So, all that snow must have fallen in September??? I am a little confused. What exactly is his snow advancement index based on? Link to comment Share on other sites More sharing options...

The snow extent itself is. Link to comment Share on other sites More sharing options...

Or a lot of it fell in early October so when you make a slope of the line through the entire month of October, it is not as steep if most of the gains are early. October SCE was impressive, the SAI was not. This year had the highest week 39 Eurasian snow cover since 1977 (week 39 is typically the end of September/beginning October).

He's going to be right now matter what. He just needs to decide which way once it's already happening. Link to comment Share on other sites More sharing options...

Nice gains and this is a bright spot in an otherwise muddied set up. Side bar...nice to see another MU Grad on here. Link to comment Share on other sites More sharing options...
billgwx Posted November 17, 2017 Share Posted November 17, 2017 At any rate, low Arctic sea ice did not lead to a large Eurasian snow advance south of 60N in October, though the total snow cover extent per Rutgers Global Snow Lab at month's end was 9th highest of the last 50 years. The time frame for SAI is really Weeks 40-44, so ending November 5th, and I'm inferring from these snow cover anomalies at the start and end of that time frame that SAI was below average this year (not sure how that positive anomaly over Tibet figures into all of this): Link to comment Share on other sites More sharing options...
