Jeff Braun and Dan Lindsey NOAA/RAMMB CIRA/CSU ***(Also, please see addendum near the end of this message) The following are a sequence of GOES-13 visible images from 19:45 UTC on 20 July 2010 to 00:45 UTC on 21 July 2010. On 20 July 2010, a United Airlines Boeing 777 aircraft experienced severe turbulence during its Continue Reading
J. Braun GOES-R ABI will have several channels in the window region from which channel difference products can be produced. Four channels, 8.5, 10.35, 11.2, and 12.3 µm can be differenced to produce a total of six difference images. In this example, differences were produced from a numerical simulation of the 27 June 2007 thunderstorm Continue Reading
Louie Grasso, Dan Lindsey and J. Braun GOES-R ABI will have several channels in the window region from which channel difference products can be produced. Four channels, 8.5, 10.35, 11.2, and 12.3 µm can be differenced to produce a total of six difference images. Shown in Fig. 1 is a loop, every five minutes, of Continue Reading
On 5 May 2009, NESDIS staff at CIRA called for Super Rapid Scan Operations (SRSO) for GOES-11 due to the forecast of severe weather in Texas. The GOES-11 SRSO activation is in preparation for the VORTEX-II field project so that high temporal resolution satellite imagery is available for this important field project. During the VORTEX-II Continue Reading
Ken Pryor A convectively active late winter season over the Great Plains has proven fruitful for the assessment of the GOES-11 imager microburst risk product. During the evening of 8 February 2009 , a line of convective storms tracked through eastern New Mexico and western Texas , producing several strong downbursts west of Lubbock . This event Continue Reading
(Courtesy NOAA/NWS – July 15, 2008) Jeff Braun Strong heating over the elevated (Mexican Plateau) desert southwest CONUS causes an area of low pressure to form known as a thermal low. Since the air pressure is relatively higher over the nearly adjacent ocean areas (Gulf of California and the Tropical Pacific) to the south and west, air flow (from high Continue Reading
(From SPC MCD 1327 – Concerning Tornado Watch #509) Jeff Braun Wednesday night, June 11, 2008, at just after 6:30 PM, some 93 boys, ages 13 to 18, along with 25 adult BSA staff members, were fighting for their lives as a deadly tornado roared through the Little Sioux Boy Scout Camp. Four of the Boy Continue Reading

Data source – NOAA/NWS; Map – FEMA) Jeff Braun Thursday, May 22, 2008 was truly a day the will live in infamy for many folks in and around the communities of western Weld County (and north eastern Larimer county), Colorado. While the city of Windsor, Colorado sustained Continue Reading
J. Braun Here is a paper/discussion presented at this year’s 13th Conference on Aviation, Range, and Aerospace Meteorology by Haig Iskenderian (from MIT) titled, “Cloud-to-Ground Lightning as a Proxy for Nowcasts of VIL and Echo Tops.” Although geared toward the aviation community, this inforamtion can be valuable to any WFO with forecasting/warning duties in their CWA in Continue Reading
Jeff Braun Below are some links to, or copies of, some perhaps lesser known meteorological training materials. Many of these have been born out of Aviation Weather programs either here in the USA through the military Air Force Weather Agency (AFWA) or the FAA, or from up north and our Canadian Neighbors. Although some of Continue Reading
