Cumulative Volume and Area: 2012.

I've been delving into the data I have on sea ice to try to a greater understanding of the changes and to be able to explain the changes in the seasonal cycles of area and volume. As part of that I've been playing around with a different way of looking at the sea ice area and volume data, running the year from the day of maximum. My aim had initially been to look at changes to the seasonal cycle without the year on year losses in volume and area, what came out of the process however needed to be dealt with before the changes in the seasonal cycle could be considered.

End of Month Miscellenea.

First there's Dr Jennifer Francis at the Weather & Climate Summit. I was lucky enough to have a day off and stumble upon this last year. This year Dr Francis covers a lot of what was covered before, and proceeds into a narrative of Arctic impacts on the wider atmosphere. Then there's new stuff from

PIOMAS gridded data - 2012 is here!

The PIOMAS team have now uploaded the 2012 gridded data to their server, here. Which means more data to analyse. The only downside - it involves programming which I'm not much good at and don't enjoy at all.

An Observation from the Brink.

This post is not reliable: See correction.

I've been thinking about the relationship between volume and area, so I plotted a scatter plot of PIOMAS volume at annual minimum and CT area at annual minimum. I can't believe I've not done this before, or if I have that I've forgotten, not having seen the significance.

Northern Hemisphere Blocking.

Over at Neven's Sea Ice Blog, Steve Bloom posted a link to some data on Northern Hemisphere blocking, I've got to work on the data Steve linked to, but haven't really got to the bottom of the matter. This data holds some exciting detail. I've not reached a firm conclusion on this, I need to read some more papers on blocking. But this post summarises where I've got to.
