Records and oddities
« on: December 22, 2013, 12:43:14 AM »
CT area has reached 5th highest daily area anomaly, the 4 higher days are consecutive days in 2007:

2007.9672   1.8403077
2007.9644   1.7662096
2007.9698   1.7593303
2007.9727   1.7178568
2013.9644   1.6992683

It was exactly the same time of year. That may not be a co-incident but there are other times of year when there are high anomalies: near .3 .5 and .6 of a year seem to feature quite frequently among high anomalies as well as near the end of the year. Didn't find any rounding to 0.1 of a year until 427th highest anomaly. I guess it isn't too surprising for there to be a change in the seasonal pattern over a long period of time.

I would like to note that while the Antarctic sea ice area/extent (and most certainly volume) are trending at historical (recorded history) highs; the most significant reason for this is that the circumpolar winds around Antarctic are abnormally high primarily due to the recurrence of the Antarctic ozone hole (because the winds push the sea ice away from ice generating locations, thus allowing more ice to generate).  Furthermore, as these high winds contribute both to increased up-welling and to the reduction in AABW (both of which contribute to the current acceleration of grounded Antarctic ice); the fact that Antarctic SIA/SIE are high supports the position that the SLR contribution from Antarctica is continuing to accelerate.

Also, I would like to note that GCM projections indicate that the Antarctic SIA/SIE should begin to decrease by 2070 (assuming that the ozone hole heals itself by then as is currently projected).

NASA | The Coldest Place in the World

Now even colder, new record low has been registered at -97.8 C
"Scientists recorded this extreme temperature on the ice sheet deep in the middle of Antarctica during the long, dark polar winter. As they report this week in Geophysical Research Letters, the team thinks this is about as cold as it can possibly get in our corner of the solar system."
