Is global warming responsible for fewer tornadoes in 2009? Stu Ostro of the Weather Channel thinks so. Image courtesy NSSL.<\/figcaption><\/figure>\n

Stormchasers across Tornado Alley have been frustrated this spring by what seems to be a lack of tornadoes and severe weather.\u00a0 Indeed, VORTEX2, the largest tornado field study ever, has been running for more than two weeks now and has not seen one twister.\u00a0 Last week, Weather Channel Senior Meteorologist Stu Ostro<\/a> speculated that global warming was the cause.<\/p>\n

In a segment with on-air meteorologist Stephanie Abrams, Ostro explained that the jet stream lingering over Canada and a continual ridge of high pressure were suppressing severe weather.\u00a0 Without the collision of low and high pressure (among other factors), tornadoes and supercell thunderstorms have a hard time forming.<\/p>\n

Ostro continued his explanation saying that atmospheric pressure in the Northern Hemisphere’s mid-latitudes between 30 and 60 degrees has increased steadily since 1970.\u00a0 He then overlaid a chart showing this increase with that of a chart that shows global average temperatures having increased over the same period.\u00a0 As he says in his blog entry<\/span><\/a>, \u201cThat parallels remarkably well the trend of globally-averaged temperatures, which has also shown a significant rise since the mid 1970s.\u201d<\/p>\n\n\n\n
