I'm curious about the unusual sight on Lake Mendota this morning (1/23/03, 9:20 am) - a "steaming", iced over lake. For those of you who can see it, is it a big crack that's causing the "steaming", or is the ice just so much "warmer" than the air?
It's amazing how much heat can radiate upward through leads and cracks in lake ice; we see this effect quite often in Hudson Bay, Canada: ftp://ftp.ssec.wisc.edu/pub/ssec/scottb/030121_MODIS_CH31_CANADA_OBS_LARGE.GIF This is a clear-sky, infra-red image -- red/yellow colours* are warm surfaces, cyan/blue colours* are cold surfaces. * colour: how Canadians spell "color" -- Scott Bachmeier University of Wisconsin - Madison / SSEC / CIMSS [EMAIL PROTECTED] http://www.ssec.wisc.edu/~scottb _______________________________________________ http://www.MadNorSki.org/ XC mailing list [EMAIL PROTECTED] http://www.danenet.org/mailman/listinfo/xc
