Thanks for stopping by. Here you will find images and video that involve my research on severe storms, specifically thunderstorms that produce tornadoes and/or downbursts. Some of the presentations are in video form and contain visualizations of storms. You may access these from the Presentation menu above. Hover over the Presentation menu to access all talks. All HD video is viewed best in full screen mode with 1080p HD quality chosen (select gear icon at the bottom right of the YouTube video window). However, due to the nature of streaming video (finite bandwidth) artifacts occur even at 1080p – especially when there are many particles being animated.
November 16, 2016: Robert Wilhelmson and I both received HPC Innovation Excellence Awards.
November 9, 2016 Severe Local Storms presentation:
August 2016: “Inside a Supertwister” – part of the NSF sponsored CADENS project. Click here for NCSA’s page dedicated to this documentary on devastating tornadoes.
June 19, 2016: NVIDIa blogs about their new IndeX software, using some of my supercell model data
June 13, 2016: Presentation at fourth annual Blue Waters Symposium in Sunriver, Oregon
First major publication on this work is in press. It will appear in the January 2017 issue of BAMS:
Orf, L., R. Wilhelmson, B. Lee, C. Finley, and A. Houston, 2017: Evolution of a Long-Track Violent Tornado within a Simulated Supercell. Bull. Am. Meteorol. Soc., in press, doi:10.1175/BAMS-D-15-00073.1. http://dx.doi.org/10.1175/BAMS-D-15-00073.1. Direct link to PDF: https://goo.gl/EDXdFf
New volume rendering of 30 meter simulation, going back to t=3000:
May 5, 2016: Two new seminar talks, see here.
February 3, 2016: New 20 meter simulation on Blue Waters produces long-track multiple vortex EF5 tornado (see below):
August 2015: David Bock, Rob Sisneros, and I submitted a video to XSEDE 2015 and it received the People’s Choice Award! Short article about it here (International Science Grid This Week); another here (The Weather Network), and more recently Science News picked it up (article here). Below is the video, which shows the cloud field of a tornadic supercell simulation run at 30 meter resolution on the Blue Waters supercomputer. It is based upon the environment that produced the 24 May 2011 long-track EF5 supercell near El Reno, OK.
