The band of thunderstorms east of Oswald's center showed some strong convection and cold cloud top temperatures as cold as -63 Fahrenheit (-52 Celsius). Those cold temperatures are indicative of high, powerful thunderstorms capable of dropping heavy rainfall.
Other satellite imagery indicated that Oswald's low-level circulation center had become well-defined, and bands of thunderstorms continued to wrap into it from the Coral Sea. The center of the low was over land and was out of the range of the satellite overpass, but also contained strong storms. Those storms are responsible for severe weather warnings issued on Jan. 24 by the Australian Bureau of Meteorology (ABM).
On Jan. 24 at 0600 UTC (1 a.m. EST/U.S/4 p.m. local time, Queensland.) the center of the remnant low pressure area was located near 19.7 south latitude and 146.8 east longitude, about 30 miles south of Townsville, Australia.
At 1:15 a.m. local time (Queensland) on Friday, Jan. 25 (1515 UTC or 10:15 a.m. EST/U.S. Jan. 24), the ABM issued a severe weather warning that included destructive winds and heavy rainfall for Capricornia, Wide Bay and Burnett and parts of the Central Coast and Whitsundays, Central Highlands and Coalfields and Southeast Coast Forecast Districts.
ABM's bulletin noted that ex-Tropical Cyclone Oswald was located over land, approximately 93.2 miles (150 km) west-northwest of Mackay and moving south-southeast at about 12.4 mph (20 kph). ABM noted that strong winds gusting to 77.7 mph (125 kph) are possible about the Central Coast-Whitsundays and Capricornia districts, while wind gusts to 56 mph (90 kph) are possible over the Wide Bay and Burnett district, including areas between Agnes Water and Sandy Cape.
Oswald's remnants continue to generate heavy rainfall, and a warning for flash flooding is also in effect. At 1 a.m. local time (Queensland) on Friday, Jan. 25 (1500 UTC or 10 a.m. EST/U.S. Jan. 24), the Yeppoon area reported almost 8 inches (198 mm) of rain had fallen since the previous day, and severe flash flooding was occurring.

The Joint Typhoon Warning Center noted that Oswald has a medium chance for regaining tropical depression status over the next day.

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:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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,...
