NASA Sees Typhoon Prapiroon Doing a "Sit and Spin" in the Philippine Sea

12.10.2012
As Typhoon Prapiroon slowed down and became quasi-stationary in the Philippine Sea NASA's Terra satellite passed overhead and captured an image of the storm.

NASA's Terra satellite passed over Typhoon Prapiroon on Oct. 11 at 0210 UTC (1010 p.m. EDT, Oct. 10) and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible image of the storm. The visible imagery clearly showed a small ragged eye, and microwave satellite imagery confirmed the eye. Satellite imagery also confirmed a well-defined low-level center of circulation.

By 11 a.m. EDT on Oct. 11, Prapiroon's maximum sustained winds were near 95 knots. It was located about 415 nautical miles south of Kadena Air Base, Okinawa, Japan, near 19.4 North and 128.5 East and not moving.

The storm slowed to a quasi-stationary position between two ridges (elongated areas) of high pressure. Prapiroon is expected to get a jump start again and get most of its steering influenced by the ridge located the east of the storm.

According to the forecasters at the Joint Typhoon Warning Center, between [12 and 24 hours from 11 a.m. EDT on Oct 11] Prapiroon is expected to Slowly re-curve around the western extent of the subtropical ridge and take on a northeastward track over the next three days.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

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...

Im Focus: Quantum Particles Form Droplets

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...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

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,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

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...
