Just to add that the symptoms Stu describes sound suspiciously like some of the things that are expected to result from the poleward climate zone shift. Recent review article abstract and link:
"Widening of the tropical belt in a changing climate "Some of the earliest unequivocal signs of climate change have been the warming of the air and ocean, thawing of land and melting of ice in the Arctic. But recent studies are showing that the tropics are also changing. Several lines of evidence show that over the past few decades the tropical belt has expanded. This expansion has potentially important implications for subtropical societies and may lead to profound changes in the global climate system. Most importantly, poleward movement of largescale atmospheric circulation systems, such as jet streams and storm tracks, could result in shifts in precipitation patterns affecting natural ecosystems, agriculture, and water resources. The implications of the expansion for stratospheric circulation and the distribution of ozone in the atmosphere are as yet poorly understood. The observed recent rate of expansion is greater than climate model projections of expansion over the twenty-first century, which suggests that there is still much to be learned about this aspect of global climate change." http://www.arl.noaa.gov/ss/climate/JournalPDFs/SeidelEtAl.ngeo.2007.38.pdf > -----Original Message----- > From: [email protected] > [mailto:[EMAIL PROTECTED] Behalf Of Steve Bloom > Sent: Monday, January 21, 2008 9:25 PM > To: [email protected] > Subject: [Global Change: 2388] One of my rare questions here > > > > For the second time Weather Channel chief meteorologist Stu Ostro has posted > (link below) > on what seems like an interesting idea that an apparent AGW-driven poleward > migration of > NH high pressure zones has resulted in an identifiable pattern of screwy > weather. > Anything to this? > > http://climate.weather.com/blog/9_14587.html > > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
