NASA's Aqua satellite passed over Tropical cyclone 15S on Feb. 18 at 10:53 a.m. EST. The Atmospheric Infrared Sounder or AIRS instrument captured infrared data on the tropical system that showed the highest cloud tops and strongest thunderstorms were in a band that stretched from the east to the south of the center.

Cloud top temperatures were near -63F/-52C, indicating high, powerful thunderstorms with potential for heavy rainfall. The eastern-most edge was over western Madagascar and the southwestern extent reached Mozambique on the African mainland.
On February 18 at 1500 UTC/10 a.m. EST, Tropical Cyclone 15S had maximum sustained winds near 35 knots/40 mph/62 kph, making it a tropical storm. 15S was centered near 18.3 south and 40.3 east, about 375 nautical miles/431.5 miles/694.5 km west of Antananarivo, Madagascar.
It was moving to the south at 5 knots/5.7 mph/9.2 kph and is expected to strengthen to hurricane-force over the next couple of days. It is generating 10 foot high waves in the Mozambique Channel.
Forecasters at the Joint Typhoon Warning Center expect 15S to drift south through the Mozambique Channel over the next couple of days and emerge in the Southern Indian Ocean in cooler waters.

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...
