NASA sees Hurricane Lane punched in the eye

19.09.2012
Powerful thunderstorms wrapped tightly around Hurricane Lane's center as it continued moving through the eastern Pacific Ocean. When NASA's Terra satellite passed over Lane it captured a close-up view of the storm and noticed that Lane's eye had become cloud-filled as if being punched in the eye. Nature is expected to fight Lane more and win over the next couple of days.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a close-up of Lane on Sept. 17 at 3:25 p.m. EDT when it was still a hurricane. In the image, Lane's eye appeared obscured by clouds as towering thunderstorms wrapped tightly around the center of circulation.

By Tuesday, Sept. 18 at 11 a.m. EDT, Lane weakened to a tropical storm. Lane's maximum sustained winds had fallen to 70 mph (110 kmh). It was centered about 1,170 miles (1,885 km) west of the southern tip of Baja California, near 20.1 North latitude and 127.9 West longitude. It was moving to the north near 9 mph (15 kmh) and is expected to turn to the northwest.

Those towering cloud tops surrounding Lane's entire eye had warmed on Tuesday, Sept. 18, indicating that they are not as high, and weaker.

Forecasters at the National Hurricane Center expect that Lane will be punched all over, not just "in the eye." There are two factors that are giving Lane a beating on Sept. 18 and 19, and those are cooler waters and increased wind shear. Lane is moving into an area where sea surface temperatures are colder than 22 Celsius (71.6 Fahrenheit), far below the 26.6C (80F) threshold needed for keeping a tropical cyclone alive. In addition, wind shear is forecast to increase from the southwest and pummel Lane at speeds of 25 knots (28.7 mph/46.3 kph), eventually "knocking it out." Lane is expected to become a remnant low pressure area by Wed., Sept. 19.

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...
