N. Hemisphere SnowcoverFebruary 12th, 2012 at 12:28 am by Bill Steffen under Bill's Blog, Weather
Thought you might like to see these images (click on each image to enlarge). The first is Northern Hemisphere snow cover over the past 30 years. The second is current snow cover in N. America (a large swath of the Northern Plains is snow free. The third is Europe/Asia (look how much of Italy and the northeast Mediterranean has a snow cover). The fourth is the 4-month difference from normal of N. Hemisphere snow cover from Dr. Bob Hart’s website at Florida State. Compare the snow cover in the U.S. last year at this time (which was a lot – up to 63% at one point with only Florida reporting no snow anywhere in the state) to this year (about 32% of the Lower 48 with a snow cover). The bitter cold and snow continue to batter much of Europe. Look at all the record low temperatures in Europe. Anchorage, Alaska is running out of places to dump snow. Anchorage reports 28″ of snow on the ground and 103″ for the season, just about double the average snowfall. Yakutat, AK has had 226.3″ of snow this winter. That’s 139.6″ more than normal! Alyeska, AK reports 564.6″ of snow since Oct. 1. On the other side of the world, check out the weather in Vostok, Antarctica. Wow, it’s summer there! Here’s the South Pole. The Antarctic icecap has grown significantly since last year at this time and is now well above average in areal extent. Parts of Australia are also having a cool summer. And, if you haven’t seen them yet, here’s the striking images of the fog coming over the high rises in Panama City, Florida. Weatherwise, it still looks like an inch or two of snow Monday night/Tuesday and then about 3″ of snow (or it could be a mix) about Thursday.
