The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured an infrared image of Cyclone Gino on Feb. 12 at 1935 UTC (2:35 p.m. EST).
On Feb. 13 at 0505 UTC (12:05 a.m. EST) the MODIS instrument aboard NASA's Terra satellite captured this visible image of Tropical Cyclone Gino in the Indian Ocean. This close-up image clearly shows the ocean surface in the middle of Gino's eye. Credit: NASA Goddard MODIS Rapid Response Team
The AIRS temperature data showed Gino maintained a large area of powerful thunderstorms with cold cloud top temperatures and a band of strong thunderstorms wrapping in from the southeast. Cloud top temperatures in both of those areas were as cold as -63 Fahrenheit (-52 Celsius), and are an indication of heavy rainfall. AIRS data during the early morning hours of Feb. 13 indicated cloud top temperatures have warmed slightly, and convection around Gino's center has weakened a little.
At 0505 UTC (12:05 a.m. EST) on Feb. 13 the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Terra satellite captured a visible image of Gino. The image clearly showed the ocean surface down through the middle of Gino's ragged eye. According to the Joint Typhoon Warning Center, microwave satellite imagery indicated that the eye is weakening on both low- and mid-levels.
By 1200 UTC (7 a.m. EST), Gino's maximum sustained winds were as high as 85 knots (97.8 mph/157.4 kph) making the storm a Category 2 hurricane on the Saffir-Simpson scale. Gino was centered near 20.6 south latitude and 79.9 east longitude, about 875 nautical miles (1,007 miles/ 1,621 km) south-southeast of Diego Garcia, and far from any land areas. Gino was moving to the south-southeast at 11 knots (12.6 mph/20.3 kph).
Gino continues to head into cooler sea surface temperatures. An approaching trough, or elongated area of low pressure is expected to increase wind shear. Those two factors will adversely affect Gino over the next couple of days.Text Credit: Rob Gutro

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
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....
