NASA's Aqua satellite passed over Extra-Tropical Storm Vongfong on Oct. 4 as it was moving away from Hokkaido, Japan, the northernmost of the big islands.
Vongfong transitioned into an extra-tropical storm early on Oct. 4 as its core changed from warm to cold.
The MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite captured a visible image of Tropical Storm Vongfong over Japan on Oct. 14 at 03:15 UTC as it was southeast of the island of Hokkaido, Japan.
The image showed that south of the center of circulation was almost devoid of clouds and showers, which were all pushed to the north and east of the center as a result of southwesterly wind shear.
At 0300 UTC on Oct. 14, the Joint Typhoon Warning Center issued its final advisory on Tropical storm Vongfong.
At that time Vongfong's center was located near 29.1 north latitude and 142.9 east longitude, about 111 nautical miles (127.7 miles/205.6 km) southeast of Misawa, Japan.
Vongfong was moving to the northeast at a speedy 36 knots (41.4 mph/66.67 kph). Vongfong's maximum sustained winds were near 35 knots (40.2 mph/64.8 kph).
Vongfong had transitioned into an extra-tropical system and will continue to move away from northern Japan and over the northwestern Pacific Ocean.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
