Strong winds gusting to around 140 mph<\/strong> (63 m s-1)<\/em> caused damage to the Reno\/Virginia Peak radar in western Nevada at around 10:30 UTC on 19 December 2008<\/strong><\/a>. GOES-13 images of the 4-km resolution 6.5 \u00c2\u00b5m “water vapor channel” (above)<\/strong><\/em> revealed a large area of “lee waves” immediately downwind of the Sierra Nevada Range — intense vertical motions associated with these lee waves were producing strong bands of subsidence (indicated by the darker blue to yellow color enhancement on the water vapor imagery),<\/em> which were likely\u00c2\u00a0 contributing to the strong wind gusts at the surface.<\/p>\n

The National Weather Service forecast office at Reno captured an AWIPS image of the 1-km resolution MODIS 6.7 \u00c2\u00b5m water vapor channel (below)<\/strong><\/em> about 4 hours prior to the time of the radar damage. Reno is one of the NWS forecast offices that receives the MODIS product suite that CIMSS distributes in AWIPS format<\/strong><\/a>.<\/p>\n

— 25 DECEMBER UPDATE —<\/strong><\/em><\/p>\n

Another round of strong winds brought gusts to 95 mph on 25 December 2008<\/strong><\/a>, which caused even more damage to the radome and the actual radar antenna structure. GOES-13 water vapor images (below)<\/strong><\/em> again showed the presence of lee waves in the region for several hours prior to the period of the peak winds (which occurred around 10:15 UTC)<\/em> — however, the arrival of dense cirrus clouds eventually masked the lee wave signature around the time of the additional radar damage.<\/p>\n
