NASA Satellite Image Sees Cyclone Victoria Looking like a “J” from Space

12.04.2013
Tropical Cyclone Victoria (Southern Indian Ocean)

When NASA’s Aqua satellite flew over Cyclone Victoria in the Southern Indian Ocean it captured a visible image of the storm and it appeared to look like the letter “J.” A band of thunderstorms wrapping into the center from the east of low-level center of circulation extended north, creating the appearance of the letter.

NASA's Aqua satellite passed over Tropical Cyclone Victoria on April 11 at 0320 UTC (April 10 at 11:20 p.m. EDT). The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard Aqua captured the visible image that showed strong thunderstorms around the center of circulation and in a band of thunderstorms wrapping around the eastern side of the storm.

On April 11 at 1500 UTC (11 a.m. EDT), Cyclone Victoria had maximum sustained winds near 50 knots (57.5 mph/92.6 kph). It was centered near 20.5 south latitude and 105.3 east longitude, about 530 nautical miles (610 miles/981.6 km) west-northwest of Learmonth, Australia. Victoria is moving to the south-southeast at 14 knots (16.1 mph/25.9 kph).

Wind shear is affecting Victoria, pushing the strongest convection (rising air that forms the thunderstorms that make up the tropical storm) and thunderstorms southeast of the center. The Joint Typhoon Warning Center forecasters noted that the wind shear is a result of a powerful jet stream located southwest of the cyclone. The wind shear is expected to continue increasing as Victoria tracks southeast, and sea surface temperatures will drop below the 80 degree Fahrenheit (26.6 Celsius) threshold needed to maintain a tropical cyclone. Those two factors are expected to weaken Victoria very quickly in the next day or two.

Im Focus: First evidence on the source of extragalactic particles

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...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

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...

Im Focus: Breaking the bond: To take part or not?

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...

Im Focus: New 2D Spectroscopy Methods

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....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

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...
