Like a Chi-clone

Subtitle: Who you gonna call?

Poignant for Professor Joe, to have his Frankenstorm predictions realized so soon, and simultaneously to understand that such occurrence forebodes severe consequences for future generations.

“Visible satellite image of the October 26, 2010 superstorm taken at 5:32pm EDT. At the time, Bigfork, Minnesota was reporting the lowest pressure ever recorded in a U.S. non-coastal storm, 955 mb.”

Climate Progress has featured a number of Extreme Weather Posts:

With the current CP post Professor Joe concludes with the really scary part: “We’ve only warmed about a degree Fahrenheit in the past half-century. We are on track to warm nearly 10 times that this century (see M.I.T. doubles its 2095 warming projection to 10°F — with 866 ppm and Arctic warming of 20°F ). In short, we ain’t seen nothing yet!”

The post and commentary to the post emphasize that this Frankenstorm is the result of global conditions. The post quotes statements by Jim Hansen, author of Storms of My Grandchildren, and Keven Trenberth, head of Climate Analysis Section at National Center for Atmospheric Research. As commentator facepalm summarizes, the rise in probability and strength [of extreme weather events] is attributable to climate change.

    Climate Progress relays findings from a new study by a Duke University-led team of climate scientists. They suggest that “global warming is the main cause of a significant intensification in the NASH (North Atlantic Subtropical High)”.

    “The NASH, commonly referred to as the Bermuda High, is an area of high pressure that forms each summer near Bermuda, where its powerful surface center helps steer Atlantic hurricanes and plays a major role in shaping weather in the eastern United States, Western Europe and northwestern Africa.”

    Mapping the North Atlantic Subtropical High
    In recent decades, the Bermuda High “has more than doubled the frequency of abnormally wet or dry summer weather in the southeastern United States.”

    Climate scientists have predicted for a long time that wild climate swings will become more the norm, e.g., “a once-in-a-century drought followed by once-in-a-century flooding.” (In fact, the flooding in Georgia was more like “a once in 500 year event.”)

    “Now a team of scientists has quantified the rise in extreme wet and dry summer weather — and finds global warming is likely the main cause.”

    By analyzing six decades of U.S. and European weather and climate data, the Duke-led team found that the center of the NASH intensified by 0.9 geopotential meters a decade on average from 1948 to 2007. (Geopotential meters are used to measure how high above sea level a pressure system extends; the greater the height, the greater the intensity.

    The team’s analysis found that as the NASH intensified, its area enlarged, bringing the high’s weather-making western ridge closer to the continental United States by 1.22 longitudinal degrees a decade.

    “This is not a natural variation like El Nino,” says lead author Wenhong Li, assistant professor of earth and ocean sciences at Duke University’s Nicholas School of the Environment. “We thoroughly investigated possible natural causes, including the Atlantic Multivariate Oscillation (AMO) and Pacific Decadal Oscillation (PDO), which may affect highs, but found no links.

    “Our analysis strongly suggests that the changes in the NASH are mainly due to anthropogenic warming,” she says.
