Cold winters caused by warmer summers, research suggests
http://www.iop.org/news/12/jan/page_53414.html[font face=Times,Times New Roman,Serif][font size=5]Cold winters caused by warmer summers, research suggests[/font]
13 January 2012 | Source: Arctic warming, increasing snow cover and widespread boreal cooling
[font size=4]Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes. [/font]
[font size=3]Their findings may throw light on specific weather incidents such as the extremely harsh Florida winter of 2010 which ended up killing a host of tropical creatures, as well as the chaos-causing snow that fell on the UK in December 2010.
Published today, Friday 13 January, in IOP Publishing’s journal Environmental Research Letters, this new research suggests that the trend of increasingly cold winters over the past two decades could be explained by warmer temperatures in the autumn having a marked effect on normal weather patterns, causing temperatures to plummet in the following winter.
The strongest winter cooling trends were observed in the eastern United States, southern Canada and much of northern Eurasia, which the researchers, based at Atmospheric and Environmental Research (AER), the University of Massachusetts and the University of Alaska Fairbanks, believe cannot be entirely explained by the natural variability of the climate system.
