NASA Satellite Imagery Shows Some Punch Left in System 94S

17.01.2014
The tropical low pressure area known as System 94S still has some punch in it as the low-level center of circulation continues to track over Western Australia and the Northern Territory.

NASA's Aqua satellite showed that thunderstorms in the low had the potential for heavy rain as it continues to track over land, and heavy rainfall warnings are in effect in the Northern Territory.

NASA's Aqua satellite passed over System 94S on January 15 at 11:59 a.m. EST and the Atmospheric Infrared Sounder instrument saw a band of powerful thunderstorms northwest of the center of the broad circulation center entering the Timor Sea from Northern Territory, Australia. Some of the thunderstorms were very high, and cloud top temperatures colder than -63F/-52C. Those temperatures are conducive to a NASA study that indicates the potential for those storms to have heavy rainfall rates.

On January 16 at 08:30 UTC/3:30 a.m. EST/6 p.m. Darwin local time, System 94S was centered about 370 nautical miles east of Broome, Australia near 18.6 south and 128.6 east. System 94S continues to track to the west and computer models indicate that it may re-emerge in the waters of the Southern Indian Ocean in the next 4 to 5 days.

The Australian Government Bureau of Meteorology or ABM for the Northern Territory issued a Severe Weather Warning for heavy rainfall and flash flooding on January 16 as the low continued to move slowly west. The warning was for residents in the Victoria River and northwest Alice Springs Districts and it was issued at 10:29 p.m. CST/local time.

At 1200 UTC/7 a.m. EST/9:30 p.m. CST/Darwin local time, System 94S was centered near latitude 19.5 south and longitude 128.7 east about 99.4 miles/160 kilometers west northwest of Rabbit Flat. The ABM forecasts the low to move south along the western border of the Northern Territory.

The Joint Typhoon Warning Center or JTWC reported that animated multispectral satellite imagery and the radar loop from Halls Creek, Australia, showed a defined circulation center with several bands of convection wrapping around the center (which is still over land). Maximum sustained surface winds were estimated as high as 20 knots.

Currently, the JTWC gives this system a low chance for development into a tropical cyclone over 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...
