NASA's newest Earth observing mission, the International Space Station-Rapid Scatterometer, or ISS-RapidScat provided a look at the winds within post-tropical cyclone Nuri on Nov. 5 and 6 as it moved parallel to Japan. Nuri has moved across the Pacific and is expected to bring hurricane-force wind gusts to Alaska's Aleutian Islands today, Nov. 7.
"RapidScat passed over Nuri, near Japan, three times within a 24 hour period," said Doug Tyler of NASA's Jet Propulsion Laboratory, Pasadena, California. "The progression [in three images] showed Nuri’s path."
On Nov. 6, Rapidscat showed Nuri's sustained wind speeds around the center of circulation were near 20 meters per second/72 km/44.7 mph (yellow).

RapidScat measured Nuri's wind speeds twice on Nov. 5 and saw strongest winds, as fast as 30 meters per second (108 kph/67.1 mph), appeared in the northwestern and southeastern quadrants. On Nov. 6, RapidScat showed sustained wind speeds around the center of circulation had decreased to near 20 meters per second (72 kph/44.7 mph).
The International Space Station-Rapid Scatterometer, or ISS-RapidScat was launched Sept. 21, 2014 to the International Space Station. From the unique vantage point of the space station, this space-based scatterometer instrument will use radar pulses reflected from the ocean's surface from different angles to calculate ocean surface wind speeds and directions.
On Friday, Nov. 7, NOAA's National Weather Service (NWS) Office in Anchorage, Alaska issued a High Wind Warning for the Western Aleutian Islands including the cities of Shemya and Amchitka. The warning was posted at 4:23 a.m. AKST on Nov 7 and remains in effect through 9 a.m. AKST on Saturday, Nov. 8.
The warning states that southwest winds 20 to 35 mph (32.1 to 56.3 kph) early on Nov. 7 will rapidly increase to south 60 to 75 mph (96.5 to 120.7 kph) with gusts of 80 to 90 mph (128.7 to 144.8 kph) by late morning. During the afternoon and evening winds will shift to the southwest and continue through Saturday morning before slowly diminishing. Any travel may be difficult. Loose debris can be moved and damage property.
Marine interests have a hurricane force wind warning through tonight, Nov. 7, as during the day, sustained winds will increase from 30 knots (34.5 mph/55.5 kph) to 70 knots (80.5 mph/129.6 kph). On the Bering side seas will be as high as 20 feet building to 28 feet in the afternoon. On the Pacific side of the islands, seas will be 24 feet (7.3 meters) building to 35 feet (10.6 meters) in the afternoon with rain. At night on Nov. 7, southwesterly winds will increase to 70 knots (80.5 mph/129.6 kph) and seas are expected to reach 45 feet (13.7 meters) in rain showers. By Saturday, Nov. 8, sustained southwesterly winds are forecast near 55 knots (63.9 mph/101.9 kph) with 39-foot (11.8 meter)-high seas on the Bering Sea side and 41-foot (12.5 meter) high seas on the Pacific side.
The marine forecast calls for strong winds to continue through Tuesday. On Sunday, Nov. 9, sustained winds are expected near 50 knots (57.5 mph/92.6 kph), Nov. 10, sustained winds forecast near 40 knots (46.0 mph/74.0 kph), and 30 knots (34.5 mph/55.5 kph) by Nov. 11. For updated forecasts, visit:

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
