Are we getting used to this? After the persistent cyclone in May and June, and the spiffy, but short-lived cyclone of two weeks ago, the Arctic is visited by yet another intense storm that goes below 980 hPa. In fact, according to Environment Canada it is currently at 976 hPa, which is lower than the lowest pressure of the previous storm (click for a larger version):
Do also note the high pressure over the Beaufort Sea, Canadian Archipelago and Greenland. Yesterday's DMI SLP map also shows the storm developing:
According to the ECMWF weather forecast the storm will stay intense today and tomorrow, and then wind down again, albeit more slowly than the last one, and accompanied by more high pressure on the American side of the Arctic (click for a larger version):
I don't know what this will do to the ice pack. The storm is pretty fierce, but still doesn't come close to the intensity and duration of last year's GAC-2012. It still isn't clear what damage the two previous storms did either, as cyclones also bring in cold and clouds.
I also don't know how unusual it is to have three of these cyclones in one single melting season. I've only been watching the ice as intently as I do now since starting the blog in 2010. There was a big, but short-lived storm in late August in 2011 and we all remember last year's Great Arctic Cyclone. It almost feels like this year the atmosphere 'wants' to do a repeat, but doesn't quite succeed because there's more ice.
But feeling isn't knowing or even speculating, so I'll leave it at that for the time being. This post will be updated if anything interesting happens.
