MIMIC Total Precipitable Water product<\/p><\/div>\n

AWIPS images of the MIMIC Total Precipitable Water<\/a><\/strong> (TPW) product (above)<\/em><\/strong> revealed the formation of a long “atmospheric river<\/strong><\/a>” of moisture over the North Atlantic Ocean during the 17-19 November 2009<\/strong> period. MIMIC TPW values were as high as 60 mm<\/strong> (darker orange color enhancement)<\/em> within the moisture plume.<\/p>\n

The surface analysis (below)<\/em><\/strong> showed that this moist plume was along and ahead of a cold front that was trailing southward from a deepening mid-latitude cyclone. This plume of moisture was contributing to very heavy rainfall and significant flooding over parts of the United Kingdom — Seathwaite reported a 24-hour rainfall amount of 12.36 inches (314 mm), which if confirmed as accurate will set a new record for 24-hour precipitation in the UK (UK Met Office<\/a><\/strong>)<\/em>.<\/p>\n

A composite of GOES-12 and Meteosat-9 water vapor imagery (below)<\/em><\/strong> suggested that this long atmospheric river tapped into a pocket of deep tropical moisture (associated with the remnants of what was formerly Hurricane\/Tropical Storm Ida),<\/em> and was then brought northward within the warm conveyor belt in advance of the deepening cyclone over the North Atlantic Ocean.<\/p>\n
