~If only sea ice extent projections were just as easy as long range projections with a paper and crayons.
projection based on refraction techniques and other means. In Green is the jet stream.
A look at this 250 mb GFS jet stream map:
The image of no Arctic sea ice at all during summer would leave Greenland as the center of the polar jet stream, this would affect weather incomprehensibly strange except for UK and Ireland with loads full more rain, but everywhere else would be weird. Although not there yet, lack of sea ice like September 2015, gives us an impression
contradicting normal El-Nino summer just past expectations :
"Although the primary effects of El Niño will likely be restricted to temperatures and snowfall in Central Canada, there could be a number of indirect consequences, such as lower grocery prices due to increases rainfall in California and a better growing season."
"The forecast isn’t so sunny for Ontario and Quebec, where Scott says temperatures are expected to be cooler than seasonal norms overall.
Both the Prairie and Atlantic provinces are forecast to see summer temperatures within seasonal averages, with Alberta trending slightly warmer."
The weather Network model got it wrong:
The apparently thorough WN essay had not one word about sea ice.
A neat current weather article of all places from Gawker:
Breaks down this end of summer extension extremely well. In particular looking at CPC's outlook completely turns the tables on the Weather Network weather projection.
To all those who try, be weary about making weather projections without considering the Polar Cryospheric prognosis.
If only sea ice extent numbers were just as easy to predict. But Global weather is changing fast, faster perhaps than anyone with experience can be useful, because geophysical patterns are becoming unconventionally changing with increasing Global Temperatures. WD September 23, 2015
