Infrared satellite imagery from shows how cold cloud top temperatures are in a tropical cyclone, and recent imagery from NASA's Aqua satellite shows the cloud-top temperatures have been warming in Tropical Storm 13W. Warming cloud top temperatures indicate less strength, and Tropical Storm 13W is weakening.
NASA's Aqua satellite passed over Tropical Storm 13W on August 7 at 0253 UTC. The AIRS instrument captured an infrared image of the cloud temperatures that showed very limited strong storms (purple) and most of the precipitation was to the east of the center of circulation.

NASA's Aqua satellite passed over Tropical Storm 13W on August 7 at 0253 UTC. The Atmospheric Infrared Sounder (AIRS) instrument that flies onboard Aqua captured an infrared image of the storm's cloud temperatures that showed very limited strong thunderstorms make up the tropical cyclone and most of the precipitation was to the east of the center of circulation. The AIRS imagery also shows that the bands of thunderstorms around the center are fragmented.
On August 7 at 1500 UTC (11 a.m. EDT), Tropical Storm 13W's (TS13W) maximum sustained winds were near 35 knots (40.2 mph/64.8 kmh). TS13W was located 745 nautical miles (857 miles/1,380 km) north-northwest of Wake Island, near 30.2 North and 160.5 East. It was moving to the northwest near 9 knots (10.3 mph/16.6 kmh).
The Joint Typhoon Warning Center forecasters noted that Tropical Storm 13W "Continues to maintain a warm core and will likely dissipate before transitioning to a subtropical or extra-tropical system."Text Credit: Rob Gutro

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...
