It is interesting to note that an increasing pressure gradient between high pressure located over the Gulf of Mexico and the deepening circulation of Hurricane Rina was beginning to enhance the intensity of dry Tehuano gap winds flowing southward into the Gulf of Tehuantepec (below)<\/em><\/strong>.<\/p>\n

On 25 October 2011<\/strong><\/a>, widespread high altitude cirrus “transverse banding” was seen along the western periphery of Hurricane Rina on a 1-km resolution NOAA-16 false color Red\/Green\/Blue (RGB) image (above),<\/strong><\/em> created using AVHRR visible channels 1 (0.63 \u00c2\u00b5m) and 2 (0.86 \u00c2\u00b5m) along with IR channel 4 (10.8 \u00c2\u00b5m).<\/p>\n

4-km resolution GOES-13 6.5 \u00c2\u00b5m “water vapor channel” images (below; click image to play animation)<\/strong><\/em> showed that Hurricane Rina was a prolific producer of transverse banding during much of the day. The GOES-13 satellite had been placed into Rapid Scan Operations (RSO) mode, providing images as often as every 5-10 minutes.<\/p>\n
