\"GOES-15<\/a>

GOES-15 “Sitka” RSO Sector<\/p><\/div>\n

During a 4-hour period on 17 March 2015, NOAA\/NESDIS conducted a test of two special GOES-15 (GOES-West)<\/em> Rapid Scan Operations (RSO) sectors for the Alaska Region. From 16:00 to 18:00 UTC, the test was conducted for the “Sitka” sector (above)<\/strong><\/em> — and GOES-15 0.63 \u00b5m visible channel images over a portion of that sector (below; click image to play animation)<\/strong><\/em> showed the circulation of a mid-latitude cyclone that was producing gale force winds in the eastern portion of the Gulf of Alaska (IR image with surface analysis<\/strong><\/a>), as well as clusters of deep convection which were forming along an occluded front approaching from the south.<\/p>\n

Then from 18:00 to 20:00 UTC, the RSO test was conducted for the “TPARC<\/strong><\/a>” sector (above)<\/strong><\/em> — and GOES-15 0.63 \u00b5m visible channel images (below; click image to play animation)<\/strong><\/em> showed the circulation of two cyclones south of the Aleutian Islands, in addition to a large “banner cloud” and a few mountain waves which had formed downwind (to the north)<\/em> of the rugged terrain of the Alaska Peninsula and the Aleutian Islands. GOES-15 IR brightness temperatures associated with the banner cloud were as cold as -65 C, which according to the nearby Bethel, Alaska rawinsonde data at 12 UTC corresponded to an altitude of around 27,700 feet (IR image with Bethel Skew-T and surface analysis<\/strong><\/a>).<\/p>\n

Regarding the Alaska Peninsula banner cloud seen on the GOES-15 visible images, a sequence of Terra\/Aqua MODIS 11.0 \u00b5m and Suomi NPP VIIRS 11.45 \u00b5m IR images (below; click image to play animation)<\/em><\/strong> showed the evolution of this feature several hours before and after the RSO test. There were a few pilot reports of moderate turbulence, at altitudes as high as 36,000 feet – and some of these pilot reports specifically mentioned “MNT WAVE” in their remarks.<\/p>\n
