Former Tropical Cyclone Emeraude was battered by northeasterly vertical wind shear and reduced to a remnant low pressure area in the Southern Indian Ocean. NASA-NOAA's Suomi NPP satellite passed over the system on March 24 captured a visible image of the large area of remnant clouds.
On Mar. 24 at 07:42 UTC (3:42 a.m. EDT) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of clouds associated with the remnant low pressure area. The poorly-defined center circulation was barely distinguishable in the imagery, although there were flaring thunderstorms occurring southwest of the center.
VIIRS collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans.
At 1800 UTC (2 p.m. EDT), the remnants of Emeraude were centered near 11.0 degrees south latitude and 85.9 degrees east longitude, about 650 nautical miles (748 miles/1,204 km) west of Cocos Island.
Maximum sustained surface winds were estimated at 20 to 25 knots (23.0 to 28.7 mph/37.0 to 46.3 kph) and the minimum sea level pressure was estimated to be near 1005 millibars.
The Joint Typhoon Warning Center noted that "upper level environment remains poor with weak divergence and strong vertical wind shear between 25 to 30 knots (28.7 to 34.5 mph/46.3 to 55.5 kph). Development is not expected over the next 24 to 48 hours, however, some dynamic models re-develop the system beyond two days."

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
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....
