China and India Cold and Snow Blitz, Canada and United States Next?

By Joseph D’Aleo, CCM

Roger Pielke Sr. aptly notes Climate Science has made as one of its main conclusions that the needed focus for the study of climate change and variability is on the regional and local scales. Global and zonally-averaged climate metrics would only be important to the extent that they provide useful information on these space scales. The recent prolonged rare cold and snow in China provides an excellent example to support this conclusion. As reported on China View under the title Experts blame snow disaster on La Nina, atmospheric circulation

See the extent of the cold across much of China and India the 8 days ending February 2, 2008. Note amounts exceed 8 degrees Celsius (nearly 15 degrees F) in many locations. See a new story today on Planet Ark

Cold is again building in western Canada and will come east and south the next few weeks. Look for more snow and cold in the news in the weeks ahead across many areas of the northern United States. This too is classic La Nina, cold Pacific Decadal Oscillation weather. Snow fell heavily in the Pacific Northwest as we often find in La Ninas. In fact in some places in Oregon, heavy enough (eighteen inches on top of 6 feet of snow already there) to cause roofs to collapse. See Idahna, Oregon Buried in Snow; Mayor Asks for Emergency Help. This story has some amazing video.

As some of the cold air first makes an appearance across the northern tier the next few days, rain will change to snow with heavy amounts once again from Chicago across the Great lakes into New York State and New England. See Tom Skilling’s blog for stories on how Chicago already ranking as the 6th snowiest in 124 years of record is facing another heavy snow this week and is headed for a 60 inch plus snow season.
