POES AVHRR visible, IR, and IR + severe weather reports<\/p><\/div>\n

A large Mesoscale Convective System (MCS) initially developed over Nebraska and quickly grew in size as it propagated eastward across the Missouri River Valley region of the north-central US on 08 August 2010<\/strong>. AWIPS images of 1-km resolution POES AVHRR 0.63 \u00c2\u00b5m visible and 10.8 \u00c2\u00b5m IR channel data (above)<\/em><\/strong> revealed an impressive back-sheared anvil structure, along with well-defined overshooting tops and very cold cloud top IR brightness temperatures (as cold as -91\u00c2\u00ba C<\/a><\/strong>). SPC storm reports<\/a><\/strong> showed a number of hail an damaging winds associated with this MCS, as well as one tornado.<\/p>\n

An alternative view of the storm can be seen using a false color Red\/Green\/Blue (RGB) image using POES AVHRR channels 1, 2, and 4 (below)<\/em><\/strong>.<\/p>\n

On the back-sheared portion of the anvil, note how warm the IR brightness temperatures were on the AVHRR 10.8 \u00c2\u00b5m IR image — due to the very thin nature of the cirrus shield, radiation from the warm ground below contributed to the IR brightness temperatures being warmer than -20\u00c2\u00ba C on that portion of the cirrus shield. However, the more accurate AVHRR Cloud Top Temperature (CTT) product (below)<\/em><\/strong> gave a much more accurate CTT of -40 to -50\u00c2\u00ba C. <\/p>\n
