Converging Weather Patterns Caused Last Winter’s Huge Snows
A Warming World Can Still See Severe Storms
The memory of last winter’s blizzards may be fading in this summer’s searing heat, but scientists studying them have detected a perfect storm of converging weather patterns that had little relation to climate change. The extraordinarily cold, snowy weather that hit parts of the U.S. East Coast and Europe was the result of a collision of two periodic weather patterns in the Atlantic and Pacific Oceans, a new study in the journal Geophysical Research Letters finds.
After analyzing 60 years of snowfall measurements, a team of scientists at Columbia University’s Lamont-Doherty Earth Observatory found that the anomalous winter was caused by two colliding weather events. El Niño, the cyclic warming of the tropical Pacific, brought wet weather to the southeastern U.S. at the same time that a strong negative phase in a pressure cycle called the North Atlantic Oscillation pushed frigid air from the arctic down the East Coast and across northwest Europe. End result: more snow.
Using a different dataset, climate scientists at the National Oceanic and Atmospheric Administration came to a similar conclusion in a report released in March.
“Snowy winters will happen regardless of climate change,” said Richard Seager, a climate scientist at Lamont-Doherty and lead author of the study. “A negative North Atlantic Oscillation this particular winter made the air colder over the eastern U.S., causing more precipitation to fall as snow. El Niño brought even more precipitation—which also fell as snow.”

Erm… Last I checked, Dallas, Texas was not on the East Coast… And I’m pretty sure it’s not in northwest Europe either.
I got stranded in Houston because of this blizzard. I had to drive back to Dallas. There was snow as far south as Conroe. I-45 was down to one or two lanes in each direction north of Centerville because of the snowpack in the left lane in each direction. This blizzard wasn’t due to Dallas having a wet winter… It was due to Dallas having a COLD FREAKING winter!
The NASA-GISS station data for Dallas only go back to 1947; but there are four stations around Dallas with data going back to 1881. I averaged these five stations together…
The stations form a nice little perimeter around DFW airport…
Here’s what the meteorological winter has been doing in the DFW area over the last 130 years…
Winters in North Texas aren’t part of the warming world that sees severe storms.
