POES AVHRR 12.0 \u00c2\u00b5m IR images + surface reports<\/p><\/div>\n

 <\/p>\n

Unusually cold conditions were seen across the North Slope region of Alaska during the 22 January – 24 January 2012<\/strong> period. A sequence of AWIPS images of 1-km resolution POES AVHRR 12.0 \u00c2\u00b5m IR channel data (above)<\/strong><\/em> showed the expansion of a large area of surface IR brightness temperatures of -50 C and colder (violet to white color enhancement)<\/em> across the interior portions of the North Slope. Nuiqsut (station identifier PAQT)<\/em> was as cold as -62 F<\/strong> (-52 C) on 24 January, and Barrow (station identifier PABR)<\/em> reached a low temperature of -45 F<\/strong> (-43 C) on 23 January (the record low temperature for the date was -47 F, and the normal low for the date is -20 F)<\/em>.<\/p>\n

Another feature of interest over the Arctic Ocean was the appearance of a number of what resembled “warm cracks”\u00c2\u00a0 in the sea ice, where IR brightness temperatures were -30 C or warmer (yellow color enhancement)<\/em> — significant amounts of thermal energy from the warmer waters below were able to “bleed up” through weaknesses and thinner areas of the sea ice, showing up as warm anomalies on the IR imagery.<\/p>\n
