What airflow, if any, is replacing the Arctic vortex?
« on: February 07, 2014, 03:07:11 AM »
This winter, much cold air is entering the northern US from the Arctic vortex. It seems that some airflow must
 be replacing the cold air entering the US. Where is the flow entering the Arctic and what effect
 is it having since it has to be warm? Or is the flow so small overall that it is having no appreciable effect
 on the Arctic?

Thanks, Bill

retiredbill, There are people here that can better answer your question than I but to look at current temperatures you can look at the ice tethered buoy's maintained by Woods Hole.

And for composite temperatures you can go to Daily Mean Temperatures North of 80 Degees North

http://ocean.dmi.dk/arctic/meant80n.uk.php

The Daily Mean 80 north numbers are warmer than last year at this time. There are threads for both of these data sets on the arctic sea ice page.

Thanks for the reply, Bruce. I should have looked in the sea ice forum to begin with. Or searched
 for the term "arctic vortex".
