This may be the wrong thread for this discussion, but I will use the timeliness of this discussion with the current storm, and ask forgiveness:
There seems to be a prevailing opinion, that there have been frequent summer storms in the Arctic. I am particularly interested in August storms, especially those strong enough to keep the storm center around 850mb for three days or more, because these are the kind of storms that can cause a massive overturning of the Arctic sea surface layers.
Last year, some posters suggested that there was a major storm in 2005, some have claimed a significant summer storm in 2008, again with no evidence I have seen. Does anyone have a chart for these storms?
If the large counterclockwise rotation of the SLP system in the E. Siberian during August 1-10 in 2007 doesn't qualify, then I don't see any obvious large Arctic storms in August of that year either.
Since 2010, I have only seen the August 2011 storm, the GAC 2012 that hit on August 4-9, and the current storm this August, that have been strong enough to cause massive ice pack disruption. If anyone could point me to the best access to archived Arctic charts, I would be willing to look through them for other August storms. I would like to see the charts for the last ten years for August, if possible.
Or is it just possible, that we didn't see these large storms moving into the CAB before the last three years? If so, then we really are in "uncharted" territory (pun intended).
