A rapidly intensifying mid-latitude cyclone (named “Cyclone Ulli<\/a><\/strong>” by the Europeans | surface analysis<\/strong><\/a>) was responsible for a high wind event as it moved over Scotland on 03 January 2012<\/strong><\/a>. A sequence of EUMETSAT<\/strong><\/a> Meteosat-9 Water Vapor (7.35 \u00b5m) images (above)<\/strong><\/em> revealed two notable signatures: (1)<\/strong> the formation of a pronounced area of warm\/dry water vapor brightness temperatures (bright yellow to orange color enhancement)<\/em> over the open water north of Ireland, which indicated a strongly forced region of rapidly descending middle-tropospheric air, and (2)<\/strong> a classic “Sting Jet”<\/em> signature (Monthly Weather Review<\/strong><\/a> | Wikipedia<\/strong><\/a>) which then moved eastward across Scotland. Just to the south of the sting jet signature, a wind gust of 78 knots (90 mph)<\/em> was recorded at Glasgow<\/strong><\/a> at 08:20 UTC<\/strong><\/a>, followed by a wind gust of 70 knots (81 mph)<\/em> at Edinburgh<\/strong><\/a> at 08:50 UTC<\/strong><\/a>.\u00c2\u00a0 There were additional reports of wind gusts in excess of 87 knots (100 mph)<\/em> at non-METAR sites in Scotland.<\/p>\n

The Sting Jet signature can also be seen in EUMETSAT Meteosat-9 Infrared (10.8 \u00b5m) images (Animated GIF<\/strong><\/a>) and EUMETSAT Meteosat-9 Visible (0.635 \u00b5m) images (Animated GIF<\/strong><\/a>).<\/p>\n

A comparison of 1-km resolution NOAA-19 Visible (0.63 \u00b5m) and Infrared (10.8 \u00b5m) images at 12:54 UTC (below)<\/strong><\/em> showed the structure of the cyclone as it was centered over the North Sea between the British Isles and Norway.<\/p>\n
