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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
