One of them has strengthened enough to be named Tropical Cyclone Lua, while the other is still getting organized and is a tropical low pressure area. The unnamed storm is currently close enough to the coast to generate warnings, while Lua is not.
When NASA's Aqua satellite passed over northern Australia on March 12 at 1711 UTC and March 13 at 0539 UTC it captured two tropical disturbances close enough to appear on one image. Tropical Cyclone Lau in on the left side of the image and is in the Southern Indian Ocean, while System 96P is pictured right, and is in the Southern Pacific Ocean. Aqua captured an infrared image of both storms' cloud top temperatures using the Atmospheric Infrared Sounder (AIRS) instrument. AIRS data showed that the coldest (purple) cloud top temperatures (colder than -63F/-52.7C).

When NASA's Aqua satellite passed over northern Australia on March 12 at 1711 UTC and March 13 at 0539 UTC it captured the two tropical disturbances close enough to appear on one image. Tropical Cyclone Lau appears on the left side of both days of satellite imagery, while System 96P appears on the right side of the images. Lua is located in the Southern Indian Ocean, while System 96P is in the Southern Pacific Ocean. Both systems seemed to grow closer over the two days and both are affecting coastal areas in northern Australia on March 13.
Aqua captured an infrared image of both storms' cloud top temperatures using the Atmospheric Infrared Sounder (AIRS) instrument. AIRS data showed that the coldest cloud top temperatures were colder than -63F/-52.7C around the center of circulation in both systems.
Tropical cyclone Lua formed off the northern coast of Western Australia. On March 13, it was a minimum tropical storm with maximum sustained winds near 35 knots (~40 mph/~65 kph). It was located about 240 miles west-northwest of Port Hedland, Australia, near 18.4 South and 115.0 East. It was barely moving at 2 knots (~2 mph/~4 kph) to the west-northwest, but is expected to turn to the east-southeast in a day or two. Forecasters at the Joint Typhoon Warning Center expect Lua to meander for a day or two before intensifying before making landfall in the Pilbara region sometime on March 16. There are currently no warnings posted yet for Tropical Storm Lua, but that is likely to change over the next couple of days.
Located to the east of Tropical Storm Lua, and in the Southern Pacific Ocean is System 96P. Although not a tropical storm, System 96P is closer to land and has caused watches and warnings to go up. There is currently a high seas weather warning for "Metarea 10/11" and a Coastal Waters Wind Warning for waters from Cape Don to Kuri Bay.
At 1200 UTC (8 a.m. EST/8:00 p.m. Australia WST) the tropical low known as System 96P was located near 12.9 South and 128.0 East, about 170 nautical miles west of Darwin and 115 nautical miles northwest of Port Keats. It was moving south at 4 knots (4.6 mph/7.4 kph).
AIRS infrared satellite imagery showed that deep convection (rising air that forms the thunderstorms that make up the tropical cyclone) is growing in size around the low-level circulation center. There are also bands of thunderstorms spiraling into the low's center. The Joint Typhoon Warning Center noted weather observations from nearby Troughton Island, located southwest of the center, showed a 10-minute sustained wind speed as high as 20 knots (23 mph/37 kph).
System 96P is in an area of warm sea surface temperatures and is getting organized. Forecasters at the Australian Bureau of Meteorology and Joint Typhoon Warning Center agree that it may become a tropical depression within the next day. The low is expected to curve towards the southeast for a landfall south of Port Keats late on March 14, or early on March 15. Residents from Dundee Beach to Port Keats to Kalamburu should monitor this storm closely and expect heavy rainfall, gusty winds, and rough surf along beaches.Text Credit: Rob Gutro

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.

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,...
