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: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
