NASA's TRMM, CloudSat and Aqua satellite captured images of Megi's clouds, rainfall and eye as they passed over the storm and saw clouds higher than 9 miles filled with ice, creating heavy rainfall.
The Tropical Rainfall Measuring Mission (TRMM) satellite passed over Typhoon Megi from its vantage point in space on October 18 at 2321 UTC (7:31 p.m. EDT) and saw that Megi was starting to re-organize after weakening from its encounter with the northern Philippines.
The TRMM team at NASA's Goddard Space Flight Center in Greenbelt, Md. creates rainfall imagery using data from various instruments aboard the satellite. Rain rates in the center of the TRMM swath were created from the TRMM Precipitation Radar (PR), the only spaceborne radar of its kind, while those in the outer portion are from the TRMM Microwave Imager (TMI). To put the image together, the rain rates were then overlaid on infrared data from the TRMM Visible Infrared Scanner. The October 18 TRMM daylight pass showed that Megi's eye was clearer than it was just a few hours earlier and that moderate to heavy rain showers were again completely surrounding the eye indicating it was strengthening at that time.
At 11 a.m. EDT (1500 UTC) on October 20, Typhoon Megi's maximum sustained winds had increased to 110 knots (126 mph). It was about 285 nautical miles south-southeast of Hong Kong, China near 18.7 North and 117.2 East. It was moving north at 8 mph (7 knots). Water vapor imagery has shown that its northern edge is eroding from strong upper level westerly winds. Infrared imagery, such as that from NASA's Atmospheric Infrared Sounder (AIRS) instrument on the Aqua satellite revealed that deep convection around the northern rim of the eyewall is decreasing indicating a weakening trend.
Typhoon Megi is forecast to make landfall on October 23 east of Hong Kong and then rapidly dissipate as a significant tropical cyclone.

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...
