NASA Sees Double Tropical Trouble in Northern Australia

14.03.2012
Northern Australia is dealing with two tropical systems today, and both were close enough to be captured on one satellite image.

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.

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
