NASA Eyes Post-Tropical Storm Nuri's Winds, Now to Affect Alaska

10.11.2014

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).

These two images of Nuri's sustained winds were taken by Rapidscat on Nov. 5. Strongest winds (red) as fast as 30 meters per second (108 kph/67.1 mph) appeared in the northwestern and southeastern quadrants.

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:

ISS-RapidScat is a partnership between JPL and the International Space Station Program Office at JSC, with support from the Earth Science Division of NASA's Science Mission Directorate, Washington. Other mission partners include the Kennedy Space Center, Florida; NASA's Marshall Space Flight Center, Huntsville, Alabama; the European Space Agency; and SpaceX.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
