Grace came together quickly and her winds were near 65 mph soon after formation. Very early this morning those sustained winds peaked at 70 mph, but fell back to 65 mph. Grace's existence will be short-lived as she's expected to merge with another low pressure area.
It was late last night, October 4 at around 11 p.m. EDT, when Tropical Storm Grace formed about 420 miles northeast of the Azores, near 41.2 North and 20.3 West. By 5 a.m. today, October 5, was speeding north-northeast between the Azores and the British Isles.
Grace had moved to a position about 575 miles southwest of Cork Ireland, and about 590 miles northwest of Lisbon, Portugal near 45.4 North and 16.4 West. Her maximum sustained winds were near 65 mph, and she was speeding northeast near 31 mph. Estimated minimum central pressure is 990 millibars.
NASA's Aqua satellite AIRS instrument captured an infrared image of Grace's clouds on October 4 at 10:17 a.m. EDT more than 12 hours before she came together as a tropical storm. In the infrared imagery, which measures cloud top temperatures, there were some strong areas of convection, but the storm didn't yet have the signature appearance of a tropical storm. However, the storm quickly organized.
AIRS infrared imagery measures temperatures in the clouds, and found a few of the highest thunderstorm cloud tops were cold as -63 Fahrenheit, indicating some isolated strong convection even before the storm came together.
Grace is expected to be absorbed by a large non-tropical low pressure area over the northeastern Atlantic during the day sometime tomorrow and bring rainfall to Ireland.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
