Cold January

I thought it was a tad nippy last month and the statistics bear it out.

Jan08 Northern Hemisphere snow cover: largest anomaly since 1966
9 02 2008


There have been a number of indications that January 2008 has been an exceptional month for winter weather in not only North America, but the entire Northern Hemisphere.

We’ve had anecdotal evidence of odd weather in the form of wire reports from Saudi Arabia, Iraq, and China where record setting cold and snow has been felt with intensity not seen for 30-100 years, depending on the region.

From our remote sensing groups, we have reports of significant negative anomalies in both the RSS and UAH global satellite data for the lower troposphere. The there’s NOAA’s announcement that January 2008, was below 20th century averages, plus news that Arctic sea ice has quickly recovered from the record low extent of Summer 200.

Finally, there’s the massive La Nina said to be the driver of all this but may be a harbinger of a more permanent phase shift according to veteran forecaster Joe Bastardi.

Now to add to this, we have images and reports from NOAA and Rutgers University of large anomalies of snow cover extent for the northern hemisphere in January 2008.
