NASA's Atmospheric Infrared Sounder (AIRS) infrared imagery suggests that Dianne's center of circulation is consolidating and getting organized. There are bands of thunderstorms wrapping into the center of the storm, indicating strengthening is occurring.

The AIRS instrument flies aboard NASA's Aqua satellite. The AIRS infrared image of Tropical Storm Dianne from Feb. 17 at 06:05 UTC (1:05 a.m. EST) showed a large area of strong convection and powerful thunderstorms. Those cloud top temperatures in the strongest thunderstorms were as cold as or colder than -63F/-52C.
Microwave imagery from the Advanced Microwave Sounding Unit (AMSU), a multi-channel microwave radiometer installed on meteorological satellites, even indicated that an eye had formed in Dianne's center.
Tropical Storm Dianne is on a southerly track through the Southern Indian Ocean and is currently forecast to stay off shore and away from Western Australia.
At 1500 UTC (10 a.m. EST) Tropical Cyclone Dianne had maximum sustained winds near 55 knots (63 mph/101 kmh). Tropical storm-force winds extend about 60 miles from the center. Dianne was centered about 260 nautical miles (299 miles/281 km) northwest of Learmonth, Australia near 19.0 South and 110.7 East. It was creeping to the southeast at 1 knot (1 mph/2 kmh). Dianne continues to generate waves as high as 19 feet (~6 meters) in that area of the Southern Indian Ocean.
The Joint Typhoon Warning Center (JTWC) expects Dianne to stop meandering and start moving south on Feb. 18 while intensifying. The JWTC does expect that Dianne will remain well west of the Australian coast. However, there are warnings posted for Western Australia. A Cyclone Warning is currently in effect for coastal areas from Exmouth to Coral Bay and a Cyclone Watch is in effect for coastal areas from Onslow to Exmouth and Coral Bay to Overlander Roadhouse, including Carnarvon and Denham.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

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,...
