Title:
Shelf Cloud Over Saskatchewan
Explanation:
Perhaps it's time to go inside. Such thoughts might occur to people witnessing the approach of an impressive shelf cloud [ http://en.wikipedia…]. Shelf clouds are typically seen leading thunderstorms [ http://www.nssl.noa…], although they may precede [ http://en.wikipedia…] any well defined front of relatively cold air. Shelf clouds [ http://www.targetar…] differ from roll clouds [ http://antwrp.gsfc.…] because shelf clouds are attached to a larger cloud system lurking above. Similarly, shelf clouds [ http://eo.ucar.edu/…] differ from wall clouds because wall clouds typically trail storm system [ http://www.youtube.…]s. The above pictured shelf cloud [ http://www.crh.noaa…] was photographed toward the southwest during a trip crossing the prairies of Saskatchewan [ http://en.wikipedia…], Canada [ http://en.wikipedia…] on the Trans-Canada Highway [ http://www.jpgmag.c…] in 2001 August. A rising Sun [ http://antwrp.gsfc.…] illuminated the impressive cloud [ http://antwrp.gsfc.…] from the east as it advanced from the west.
