NOAA's Geostationary Operational Environmental Satellite, GOES-13, captures visible and infrared images of weather over the eastern U.S. every 15 minutes, and captured the movement of the weather system that generated the Texas twisters.
The 23 second movie runs from April 2 at 1615 UTC through April 4 at 1615 UTC (11:15 a.m. CDT), and shows the progression of the storm system that generated about 15 tornadoes on April 3. Around 2215 UTC (5:15 p.m. CDT) on April 3, the tail end of the front appeared in the GOES animation as a pie-shaped wedge that continued to thin out.
It is that wedge where the tornadoes were generated and touched down in the southeastern Dallas suburbs. One thing people viewing the video can take from the satellite view is that if they're seeing GOES imagery live on television, they can relate wedge shaped-frontal clouds with severe weather and be prepared.
NOAA operates the GOES series of satellites, and NASA's GOES Project, located at NASA's Goddard Space Flight Center in Greenbelt, Md. compiles the images into animations. The GOES visible and infrared data is compiled and then overlayed on a true-color land surface map of the U.S. that was created using data from the Moderate Resolution Imaging Spectroradiometer instrument that flies on NASA's Aqua and Terra satellites.
At least 15 tornadoes were reported in Texas yesterday afternoon, south and southeast of the Dallas metro area. According to the National Weather Service, reports of tornadoes were from: 4 miles south of Cumby; 3 to 5 miles south of Royse City; 5 miles south of Sulphur Springs and in the town, Campbell, 10 miles west of Quinlan, 4 miles southeast of Pickton, 4 miles north of Lone Oak, Lancaster, Forney, Cleburne, Everman, Oak Leaf, and Mesquite. The National Weather Service's Fort Worth office noted that most of the tornadoes were between EF2 and EF1 on the Fujita scale. According to WFAA-TV meteorologist Steve McCauley, preliminary analysis showed that EF-2 tornadoes (with max. winds of 130 mph) struck Arlington and Lancaster, and an EF-3 (150 mph winds) hit Forney. A National Weather Service website was created to provide reports of hail, wind and tornado reports at: https://nwschat.weather.gov/lsr/#FWD/201204030500/201204040440/0100.
Live video shot on April 3 on the south side of Dallas aired on the Weather Channel that showed semi-tractor trailer truck s being lifted about 50 feet in the air from the tornado. Local Dallas-area television station WFAA-TV provided a severe weather blog that covers many incidents related to the storms. It can be found here: http://www.wfaa.com/news/weather/Severe-weather-blog-Tornado-warnings-issued-145963545.html
Anyone who experiences severe storms on the ground would likely want to see how they appear to develop in satellite view, as it may provide extra warning time. GOES satellites continue to provide continuous coverage over the entire U.S., as the clean up continues today in Texas.You can view a related video here:

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.
Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren't the type...
Study co-led by Berkeley Lab reveals how wavelike plasmons could power up a new class of sensing and photochemical technologies at the nanoscale
Wavelike, collective oscillations of electrons known as "plasmons" are very important for determining the optical and electronic properties of metals.
