The fifth tropical cyclone of the Northern Indian Ocean season formed in the Bay of Bengal as NASA's Terra satellite passed overhead and captured an image of the storm.
When Terra passed over Tropical Cyclone 5B on Nov. 6 at 05:05 UTC (12:05 a.m. EST), the MODIS instrument aboard took a visible image of the storm.
The MODIS image showed a concentrated storm with strong thunderstorms circling tight around the center and in the northeastern quadrant.
By 1500 UTC (10 a.m. EST), Tropical Cyclone 5B was located near 13.4 north latitude and 87.9 east longitude. That's about 380 nautical miles (437.3 miles/703.8 km) southeast of Visakhapatnam, India.
Tropical Cyclone 5B had maximum sustained winds near 35 knots (40.2 mph/64.8 kph). It was moving slowly to the south-southeast.
Forecasters at the Joint Typhoon Warning Center said that an upper-level (atmospheric) analysis indicates the system remains in a generally favorable environment with moderate vertical wind shear and good outflow.
Additionally, sea surface temperatures are relatively high in this region, which will help it maintain strength and slightly intensify over the next two days.
JWTC forecasters expect Tropical Cyclone 5B to make landfall near Chennai on Nov. 9 and dissipate over land quickly.

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....
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...
