NASA sees Tropical Storm Heidi approaching Australia's Pilbara coast

12.01.2012
Tropical Storm Heidi is forecast to make landfall today along the Pilbara coast of Western Australia as warnings pepper the coast.

NASA's Aqua satellite passed overhead early in the day and captured a visible image showing Heidi's center still north of the Pilbara coast, while her outer bands continue to bring rainfall and gusty winds to coastal residents.

NASA's Aqua satellite passed over Heidi on January 11, 2012 at 02:30 UTC (Jan. 10 at 10:30 a.m. EST) and the Moderate Resolution Imaging Spectroradiometer captured a visible image of the storm. The image showed that Heidi maintained her well-rounded shape and her center was just north of the Pilbara Coast of Western Australia at that time.

There are several warnings in effect in Australia as Heidi approaches. According to the Australian Bureau of Meteorology (ABM), a Cyclone Warning is active for "coastal areas from Wallal to Dampier, including Port Hedland, Roebourne, Karratha and Dampier, and extends to adjacent inland parts." In addition, a Red Alert is up for the "coastal and island communities between Pardoo and Whim Creek, including the communities of Pardoo, Port Hedland, South Hedland, and Whim Creek." A Blue Alert is in effect for the "coastal and island communities between Whim Creek and Dampier, including the communities of Roebourne, Pt Samson, Karratha, and Dampier."

At 1500 UTC (10 a.m. EST) Heidi's maximum sustained winds have increased to 55 knots (63 mph/101 kmh. Heidi's center was still off-shore at about 45 nautical miles (52 miles/83 km) north-northeast of Port Hedland, Australia near 19.6 South and 118.9 East. Heidi was moving slowly at 4 knots (5 mph/7 kph) to the south-southwest.

NASA's Atmospheric Infrared Sounder (AIRS) instrument captured an image of Heidi at the same time as the MODIS instrument because they fly aboard the same satellite. The infrared data showed that Heidi was becoming more tightly wound. Forecasters using the AIRS data at the Joint Typhoon Warning Center noted that there is "convection gathering more directly over the top of the system."

Heidi is expected to strengthen a little more before making landfall because it's in an area of low vertical wind shear (winds that can weaken a storm or tear it apart) and sea surface temperatures warmer than needed to maintain a tropical cyclone. The sea surface temperatures off the Pilbara coast are near 30 degrees Celsius (86 F) and only 26.6C (80F) is needed to sustain a tropical cyclone. Anything warmer adds power to the cyclone through evaporation.

The ABM's forecast track for Heidi can be seen on their website at: http://www.bom.gov.au/products/IDW60281.shtml.

Heidi is expected intensify until it makes landfall. Landfall is expected today between Port Hedland and Point Samson. Heidi is expected to weaken after landfall as it heads to the south-southwest over the next couple of days.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
