Different views of this storm were provided by GOES-15<\/strong> (GOES-West),<\/em> GOES-14<\/strong> (in SRSO-R<\/strong><\/a> mode),<\/em> and GOES-13<\/strong> (GOES-East)<\/em> 0.62 \u00b5m visible channel images (above; click image to play 190 MB animated GIF; also available as an MP4 movie file<\/a>, or on YouTube<\/a>)<\/strong><\/em>. This comparison highlights the advantages of 1-minute interval Super Rapid Scan images (which will be available from GOES-R<\/strong><\/a>) compared to the standard 15-minute interval Routine Scan images provided by the current generation of GOES.<\/p>\n

One interesting feature seen on the visible channel images above was the apparent merger of the large dominant dryline storm and a smaller northward-moving storm that had formed in Mexico (radar animation<\/strong><\/a>). In GOES-13 10.7 \u00b5m IR imagery with an overlay of SPC storm reports (below; click image to play animation),<\/strong><\/em> one report of 2.0-inch diameter hail was seen around or shortly after the time of the storm merger.<\/p>\n

With higher spatial resolution IR imagery from MODIS (1-km),<\/em> VIIRS (375-meter),<\/em> and AVHRR (1-km),<\/em> much colder cloud-top IR brightness temperatures were seen (below)<\/strong><\/em> compared to the corresponding 4-km resolution GOES IR imagery at those times — especially during the early formative stages of the thunderstorms captured with MODIS and VIIRS. The coldest cloud-top IR brightness temperature on the 2128 UTC AVHHRR image was -80\u00ba C, compared to -67\u00ba C on the 2130 UTC GOES image.<\/p>\n
