NASA's Aqua Satellite sees Tropical Depression Anthony heading toward Australia

27.01.2011
NASA's Aqua Satellite captured a visible image of the former Tropical Storm Anthony, now weakened to a tropical depression, but forecasters aren't counting Anthony out yet. Despite its weakened condition Anthony continues to move west toward Queensland, Australia and into a more favorable area for sustaining a tropical cyclone.

The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured a visible image on Jan. 26 at 03:23 UTC of Tropical Depression Anthony in the South Pacific Ocean. The image revealed a cloud-filled center of the storm.

At 0600 UTC (1 a.m. EST) on January 26, Anthony had progressed west and was now about 455 nautical miles west-northwest of Nomeau, New Caledonia. That places Anthony's center near 19.2 South and 159.1 East. Maximum sustained surface winds are estimated at 25 to 30 knots (28 mph/46 km/hr to 34 mph/55 km/hr) meaning that Anthony is still at tropical depression status.

The infrared imagery from the AIRS instrument showed a well-defined low level circulation center, although dry air is now wrapping into Anthony's northern quadrant. Dry air saps the moisture that creates the thunderstorms that power a tropical cyclone. Generally, the storm's convection (rapidly rising air that creates those thunderstorms) is weak throughout the storm, and only isolated strong areas of convection appear in the southeastern quadrant. That may change in the next day or two, however, as Anthony moves into an area more conducive to maintaining a tropical cyclone.

Vertical wind shear (winds that can weaken a tropical cyclone) has lessened and sea surface temperatures are warm enough to sustain and strengthen a tropical cyclone (between 28 and 30 Celsius/82 and 86 Fahrenheit). Computer forecast models have shown forecasters at the Joint Typhoon Warning Center that as the system tracks westward toward Australia, there is a fair chance that Anthony will regenerate or re-strengthen in the next 24-36 hours. Forecasters in Queensland, Australia will be watching Anthony very closely.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
