NASA Sees System 91B Lingering over Southwestern India

09.05.2014

The tropical low pressure area known as System 91B has been making a slow northerly crawl while sitting inland in southwestern India, and NASA's Terra satellite captured a visible image of the struggling storm that showed half of it is over the Northern Indian Ocean.

NASA's Terra satellite passed over System 91B over southwestern India and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible image on May 8 at 05:40 UTC/1:40 a.m. EDT.

The despite having a poorly defined low-level circulation center on infrared imagery, the circulation is visible in the MODIS image. The MODIS image shows that the eastern quadrant of the broad tropical low pressure system remains over southwestern India, while the western quadrant extends into the Northern Indian Ocean. The thunderstorms are fragmented in the low pressure area.

The Joint Typhoon Warning Center (JTWC) estimates that the low-level center of System 91B is near 10.1 north latitude and 76.4 east longitude, just 20 nautical miles (23.0 miles/37.0 km) north-northeast of Cochin, India.

The center of the storm has moved to the north over the last day and is about 15 nautical miles (17.2 miles/27.8 km) closer to Cochin than it was on May 7, indicating that it is a very slow moving system.

On May 8, JTWC's website noted "upper-level analysis (of the atmosphere) indicates a marginal environment with moderate, easterly vertical wind shear offset by strong diffluence (upper air flowing off or away from the center of the storm).

Maximum sustained surface winds are estimated between 10 to 15 knots (11.5 to 17.2 mph/18.5 to 27.7 kph) as they were on May 7, so the winds have not weakened. Minimum sea level pressure is estimated to be near 1006 millibars.

As System 91B continues to linger over land, it continues to have a low chance for developing into a significant tropical cyclone within the next 24 hours.

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...
