NASA Casts Infrared Eye on Southern Indian Ocean's Tropical Cyclone Claudia

10.12.2012
The third tropical cyclone in the Southern Indian Ocean has been renamed Tropical Cyclone Claudia as NASA's Aqua satellite passed overhead.The AIRS instrument on Aqua captured infrared imagery of Claudia over two days that showed the western quadrant is most powerful part of the cyclone.

Aqua flew over Tropical Cyclone Claudia on Dec. 6 at 1959 UTC (2:59 p.m. EST/U.S.) and Dec. 7 at 0811 UTC (3:11 a.m. EST/U.S.). The Atmospheric Infrared Sounder (AIRS) instrument analyzes storms in infrared light, and revealed the temperatures of clouds and sea surface around the storm. On Dec. 6, the coldest cloud top temperatures (colder than -63F/-52C) were located in the northwestern quadrant of the storm.

The next day, those strongest storms had shifted to the west and southwestern quadrants. The AIRS data on Dec. 7 also showed a much wider center of circulation, which was slightly exposed to outer winds. Thunderstorm development was also increasing around the center of circulation.

On Dec. 7 at 1500 UTC (10 a.m. EST), newly renamed Tropical Storm Claudia, formely Tropical Storm 03S had maximum sustained winds near 45 knots. Claudia was moving in a southerly direction and away from Diego Garcia. Claudia was centered near 14.3 south latitude and 75.4 east longitude, about 445 nautical miles south of Diego Garcia. Claudia is on a south-southwesterly track, but is expected to shift more to the south over the next several days.

Claudia is currently in an area of moderate (10 to 20 knots) vertical wind shear and sea surface temperatures warm enough to keep it going. AIRS data indicates that sea surface temperatures were near 28 to 29 degrees Celsius.

Over the weekend of Dec. 8 and 9, however, Claudia will venture into cooler waters and the vertical wind shear is forecast to increase. Those two factors indicate that Claudia will weaken and become an extra-tropical storm over the weekend.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
