As a comparison, March 12th 2012 was somewhat warmer, but then we had a #e summer.
Temps in 2012 for March 23rd got up to around 16-17c..
Maybe we're going to get a warm summer this year?
The most important mode of variation in the Arctic’s winter atmospheric circulation is the Arctic Oscillation. When the Arctic Oscillation is in a negative mode or phase, sea level pressure is higher than normal over the central Arctic and lower than normal over middle latitudes. This pattern tends to keep the high Arctic relatively warm. It brings colder weather to Europe and North America because air masses can cross into and out of the high Arctic more easily. This pattern tends to favor the retention of thick ice in the Arctic basin by reducing the outflow of ice through the Fram Strait and strengthening the Beaufort Gyre, a clockwise circular pattern of ice drift in the central Arctic. The opposite conditions generally hold for a positive Arctic Oscillation pattern.
Linking Weird Weather to Rapid Warming of the Arctic
The loss of Arctic summer sea ice and the rapid warming of the Far North are altering the jet stream over North America, Europe, and Russia. Scientists are now just beginning to understand how these profound shifts may be increasing the likelihood of more persistent and extreme weather.
Does it seem as though your weather has become increasingly “stuck” lately? Day after day of cold, rain, heat, or blue skies may not be a figment of your imagination. While various oceanic and atmospheric patterns such as El Niño, La Niña, and the North Atlantic Oscillation have been blamed for the spate of unusual weather recently, there’s now a new culprit in the wind: Arctic amplification. Directly related to sea-ice loss and earlier snowmelt in the Far North, it is affecting the jet stream around the Northern Hemisphere, with potentially far-reaching effects on the weather.
