NASA Sees Tropical Storm Pewa Develop in Central Pacific

19.08.2013
NASA's Aqua satellite passed over two developing low pressure areas in the Central Pacific Ocean, just before one of them strengthened into Tropical Storm Pewa.

When NASA's Aqua satellite passed over the Central Pacific on Aug. 16 at 00:35 UTC (8:35 p.m. EDT/Aug. 15), the Moderate Resolution Imaging Spectroradiometer or MODIS instrument captured a visible image of two developing low pressure areas. The low farthest west was called System 91C, and that's the low that strengthened into Tropical Storm Pewa. The low pressure area east of Pewa is System 90C, which has a high chance to develop into a tropical depression.

System 90C is located near 12.6 north and 163.5 west, which is about 775 miles south-southwest of Kauai, Hawaii. System 90C is moving west near 15 mph.

NOAA's Central Pacific Hurricane Center or CPHC noted that outflow from Tropical Storm Pewa is adversely affecting System 90C's chances for developing further. Satellite imagery early on Aug. 16 showed that System 90C appears less organized than it did on Aug. 15. This system has a medium chance, 30 percent, of becoming a tropical cyclone during the next 48 hours.

There's another low pressure area east of System 90C, but it has a "near zero" percent chance of development. The area is actually a trough or elongated area of low pressure, and has not been given a system designation. It is producing disorganized showers and thunderstorms and was moving west at 15 to 20 mph. Because environmental conditions are not favorable, this low is not likely to become a tropical depression in the near future, according to CPHC.

On Aug. 16 at 1500 UTC/11 a.m. EDT/5 a.m. Hawaii Standard Time, Tropical Storm Pewa's maximum sustained winds were near 40 mph/65 kph. Pewa was centered near 10.2 north and 173.5 west, more than 1,250 miles southwest of Kauai, Hawaii. Pewa is moving to the west-northwest at 15 mph. The Central Pacific Hurricane Center forecast for Pewa takes the storm on a northwesterly track with its center staying over open ocean. Pewa is expected to maintain tropical storm status for the next several days.

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...
