Ez így nem teljesen igaz, az alacsony napfoltaktivitás, a negatív NAO csak kettõ azokból az igenis fontos jellemzõkbõl, amik alapján több meteorológus és szolgálat is hideg telet vár.
Bastardi is, de nem csak õ: (tudjuk, õ mindig hideg telet vár... nyilván nem realista vidám)

"What to look for during November
During the next few weeks, we will monitor the following variables to prepare our official winter forecast:
Temperature of the polar stratosphere, particularly a steady warming trend which would make a colder than average winter more likely;
Signs of the next westerly wind burst in the Pacific centred 180 degrees West;
Growing pool of colder than normal surface Atlantic waters off Newfoundland which would promote higher confidence in a colder than average winter;
Extent of snow cover over Asia as a means of gauging of the likely extent of cold air further into the winter;
The value of globally averaged angular momentum to determine whether El Nino is impacting the global weather pattern."

Ez minimum 3-4 további hasonló, hidegebb télre utaló jel.
