Ken Pryor (NESDIS / STAR) A GOES sounder-derived Microburst Windspeed Potential (MWP) algorithm, based on convective available potential energy (CAPE), and vertical temperature and humidity lapse rates, and based on the vertical difference in equivalent potential temperature (theta-e difference, TED) between the surface and middle-troposphere (between 10,000 and 20,000 feet above ground level) recently observed Continue Reading

This blog entry will consider the synthetic IR imagery from the NSSL 4-km WRF-ARW model for 19 April 2011.  There were many severe weather reports on this day: http://www.spc.noaa.gov/climo/reports/110419_rpts.html The synthetic IR imagery from the WRF-ARW model from 1200 to 2300 UTC (from the 0000 UTC 19 April 2011 model run) is given here: http://rammb.cira.colostate.edu/visit/web/19april11/loop_synthetic_ir.asp Continue Reading

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

Ken Pryor (NESDIS) The VISIT lesson “Forecasting Convective Downburst Potential Using GOES Sounder Derived Products” presents current applications of a suite of GOES sounder-derived products. The lesson has been recently revised to include updated imagery examples, and new case studies of downburst events that occurred over the United States Great Plains during June and August 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 served as another Continue Reading
