NASA's Terra satellite flew over Typhoon In-fa on Nov. 23 and imagery showed the storm had become elongated to the northeast.
On Nov. 23 at 02:00 UTC (Nov. 22 at 9 p.m. EST) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured an image of Typhoon In-fa in the Pacific Ocean.
In-fa's cloud-filled eye was surrounded by powerful thunderstorms. A large band of thunderstorms were wrapping into the low-level center in the northeastern quadrant, and stretching east.
Forecasters at the Joint Typhoon Warning Center noted that the system continues to be elongated to the northeast along the leading edge of an approaching mid-Latitude trough (elongated area of low pressure).
On Nov. 23 at 1500 UTC (10 a.m. EST), Typhoon In-fa had maximum sustained winds near 90 knots (103.6 mph/ 166.7 kph). Typhoon-force winds only extend nautical 25 miles (28.7 miles/46.3 km) from the center.
It was centered near 16.9 north latitude and 131.3 east longitude, about 734 nautical miles (844.7 miles/1,359 km) southwest of Iwo To, Japan.
In-fa was moving to the north-northwest at 4 knots (4.6 mph/7.4 kph) and is expected to curve to the northeast.
Environmental conditions are expected to continue to deteriorate as vertical wind shear rapidly increases due to the strong westerly winds from the approaching trough.
The Joint Typhoon Warning Center expects In-fa to weaken over the next couple of days and become an extra-tropical storm.
In-fa is forecast to approach the island of Iwo To, Japan on Nov. 26 and move in a northeasterly direction.

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...
