Alberto Now a Tropical Depression, Seen by NASA

23.05.2012
Infrared satellite imagery from NASA's Aqua satellite revealed Alberto weakened from a tropical storm to a tropical depression as it appears more disorganized. At 10:30 a.m. EDT on May 21, Tropical Storm Alberto weakened to a tropical depression, and has maintained that status today, May 22.

As of 5 a.m. EDT on May 22, Alberto's maximum sustained winds were near 35 mph (55 kph) but he is expected to weaken in 24 hours. Alberto was centered about 220 miles south of Cape Hatteras, North Carolina, near 32.0 North and 75.5 West. Alberto was moving to the northeast near 15 mph (24 kph), and had a minimum central pressure of 1008 millibars.

Over two days, NASA's Aqua satellite captured infrared images of Alberto and saw it's deterioration from a tropical storm to a tropical depression. The infrared images were captured from the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite on May 20 and May 21. The coldest cloud top temperatures were as cold as -63F (-52C) and indicated the strongest thunderstorms with the heaviest rainfall.

On May 22, a visible image from NOAA's GOES-15 satellite showed Alberto off the coast of North Carolina. The depression appeared to look almost wedge-shaped as it continues to weaken and move to the northeast. The image was created by the NASA GOES Project at NASA's Goddard Space Flight Center, Greenbelt, Md.

The National Hurricane Center expects Alberto to continue moving northeast and speed up. As Alberto speeds up, it is expected to weaken and could become a post-tropical remnant low pressure area by Wednesday and dissipate by Thursday, May 24.

Im Focus: Future electronic components to be printed like newspapers

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...

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....
