Atmospheric rivers set to increase UK winter flooding
http://www.iop.org/news/13/jul/page_60647.html[font face=Serif][font size=5]Atmospheric rivers set to increase UK winter flooding[/font]
24 July 2013
[font size=4]The prolonged heat wave that has bathed the UK in sunshine over the past month has given the country an unexpected taste of summer that has seemed to be missing in recent years[/font]
[font size=3]However, a new study published today, 24 July, in IOP Publishing’s Environmental Research Letters, has provided warnings that will chime with those accustomed to more typical British weather.
According to the study, winter flooding in the UK is set to get more severe and more frequent under the influence of climate change as a result of a change in the characteristics of atmospheric rivers (ARs).
ARs are narrow regions of intense moisture flows in the lower troposphere of the atmosphere that deliver sustained and heavy rainfall to mid-latitude regions such as the UK.
They are responsible for many of the largest winter floods in the mid-latitudes and can carry extremely large amounts of water: the AR responsible for flooding in the northwest of the UK in 2009 transported 4500 times more water than the average flow in the River Thames in London.
