McIDAS images of GOES-13 0.63 \u00c2\u00b5m visible channel data (above; click image to play animation)<\/strong><\/em> showed the development of a batch of cumulus clouds over the central Gulf of Mexico during the day on 13 February 2011<\/strong><\/a>. Other features of interest on the visible imagery include the rapidly-melting snow cover over the portions of the southern Plains, and a few small smoke plumes drifting northeastward due to fires burning in some of the Gulf Coast states.<\/p>\n

A comparison of AWIPS images of the 1-km resolution MODIS 0.65 \u00c2\u00b5m visible channel and the corresponding MODIS Sea Surface Temperature (SST) product (below)<\/strong><\/em> indicated that this area of cumulus development was occurring over the warmer waters of the Gulf of Mexico “Loop Current”, where SST values were as warm as 78\u00c2\u00ba F<\/strong> (darker orange color enhancement)<\/em>. As a seasonally cool northeasterly flow of air moved across the warmer Loop Current, enough instability was generated to lead to the formation of shallow cumulus clouds.<\/p>\n

About 3 hours later, a similar comparison of a 1-km resolution POES AVHRR 0.63 \u00c2\u00b5m visible image with the corresponding POES AVHRR Sea Surface Temperature product (below)<\/strong><\/em> showed a few more cumulus lines forming over the northern portion of the Loop Current, with the cumulus cloud field becoming more dense in the southern portion.<\/p>\n
