The Global Precipitation Measurement mission or GPM core satellite gathered rainfall data on the severe storms that impacted the southeastern U.S. over two days. From Tuesday evening, Nov. 29 through Wednesday morning, Nov. 30, 2016 tornadoes formed along a squall line in advance of a cold front that moved through the Southeast. Over three dozen tornadoes were reported with sightings occurring in Louisiana, Alabama, Mississippi, Tennessee and Alabama.
Tornadoes caused the deaths of at least five people in northern Alabama. Storms also took the lives of two people in Tennessee.
The GPM core observatory satellite viewed a western portion of a line of violent weather when it flew over on Tuesday, Nov. 29 at 11:16 p.m. EST. The areas covered by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments are shown in lighter shades. Red symbols show the approximate locations where tornadoes were reported.

This rainfall may provide some relief to drought ridden eastern Tennessee where destructive wildfires have been occurring. Some storms were accompanied with hail, strong winds and intense showers. Golf ball sized hail was reported in a storm that passed through Louisiana Tuesday evening.
The GPM core observatory satellite viewed a western portion of a line of violent weather when it flew over on Tuesday, Nov. 29 at 11:16 p.m. EST (November 30, 2016 0416 UTC). GPM found that rain was falling at a rate of over 5.7 inches (144.8 mm) per hour in a heavy downpours over southwestern Louisiana.
At NASA's Goddard Space Flight Center in Greenbelt, Maryland, GPM's Dual-Frequency Precipitation Radar (DPR) data was used to produce a 3-D view of the precipitation within storms that were moving over Louisiana. Storm tops were measured by GPM's radar (Ka and Ku band) reaching heights above 8 miles (13 km).
On Nov. 30, NOAA's National Weather Service Storm Prediction Center (SPC) noted "Storms will be capable of producing damaging winds, hail, heavy downpours, and a few tornadoes.
Heavy rainfall could lead to localized flooding of low lying and poor drainage areas. Additional heavy rainfall will also be possible from the Appalachians to the Middle Atlantic Region." For updated information from the SPC, visit: http://www.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
