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: Electrons in the fast lane

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.

Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....

Im Focus: The lightest electromagnetic shielding material in the world

Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.

Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

Im Focus: AI monitoring of laser welding processes - X-ray vision and eavesdropping ensure quality

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.

Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
