A warmer world may mean more snow-in some areas
A recent story by the Associated Press's Seith Borenstein about global warming causing more blizzards sure stirred up the blogosphere. But even if the trend here in D.C. is for decreasing winter snows as shown in this Capital Weather Gang story, some areas are likely to see increasing winter snows in a warming climate. Here's where and why. Look at this satellite view of New York from two days ago.
Lake Ontario is almost completely ice free. The water temperture is 35°. Here is how New York State looks today.
The Lake Effect snow machine is really going with the cold arctic air sweeping across the lake and generating heavy snow in the Tug Hill area east of Lake Ontario.
The Lake Effect snows essentially stop when the Great Lakes freeze. No moisture from frozen lakes to power the local snows. But studies have shown that in a warmer climate, the Great Lakes, as now Lake Ontario, are less likely to freeze and areas downwind of the lakes are likely to receive increasing snows in the years ahead. Snow lovers, you know where to move for more snow in the coming years. Syracuse and Oswego.:>)
