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:

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
