\"GOES-11
\n<\/a><\/p>\n

An animation of GOES-11 water vapor channel images (above)<\/strong><\/em> showed that Atlantic Hurricane Dean made landfall in Mexico on 22 August 2007, and eventually emerged into the Pacific basin on 23 August; the middle\/upper tropospheric moisture associated with the remnants of Dean then moved slowly northward across the Baja California region toward southern California during the next several days. AWIPS GOES-11 water vapor imagery on 26 August 2007<\/strong><\/a> (below)<\/strong><\/em> indicated that a good deal of this moisture had spread across much of the southern half of California — this residual moisture (and vorticity) was responsible for helping to initiate numerous thunderstorms (radar animation<\/a>)<\/strong><\/em>, some of which produced flash flooding, record daily rainfall, and even a waterspout<\/strong><\/a> in the San Diego area.

GOES sounder Total Precipitable Water (TPW) derived product imagery (below)<\/strong><\/em> revealed PW values as high as 40-50 mm (1.6-2.0 inches)<\/strong> over southern California at 14 UTC on 26 August.<\/p>\n

\"GOES<\/a><\/p>\n

Since the GOES sounder has 3 separate water vapor channels (6.5 \u00c2\u00b5m, 7.0 \u00c2\u00b5m, and 7.4 \u00c2\u00b5m),<\/em> the TPW can be partitioned into 3 vertical layers:<\/strong><\/a> High Layer PW, Mid Layer PW, and Low Layer PW<\/strong> components (below)<\/strong>;<\/em> on this particular day, the bulk of the TPW across southern California appeared to be in the middle layer<\/em>, which is generally between 700 and 900 hPa (1-3 km, or 3000-10,000 feet).<\/p>\n
