NASA infrared data sees birth of 10th tropical depression in Southern Indian Ocean near Australian coast

26.01.2011
NASA's Aqua satellite captured an infrared image of the very cold clouds that house powerful thunderstorms within the Southern Indian Ocean's newest tropical depression, number 10S. The depression quickly strengthened into a tropical storm and continues to affect the northern coast of Western Australia.

When Aqua passed over the Tropical Storm 10S on January 25 at 05:53 UTC (12:53 a.m. EST), the Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of the storm's clouds.

The image showed that most of the coldest cloud tops (-63 Fahrenheit/-52 Celsius) and strongest thunderstorms over appeared over the Southern Indian Ocean, and some along the extreme northern coast of Western Australia. The infrared image also showed the contrasting heat of the land.

A Cyclone Warning is current for coastal and island communities from Cape Leveque to Coral Bay. At 1500 UTC (10 a.m. EST) on January 25, Tropical Storm 10S had maximum sustained winds of 35 knots (40 mph / 64 km/hr). Tropical Storm 10S was located about 525 miles ENE of Learmonth, Australia near 17.4 South latitude and 121.8 East longitude. It was moving southwest near 15 knots (17 mph/27 km/hr). Waves along coastal areas could reach 10 feet, so beach erosion is likely, and low level flooding is possible. At 17:30 UTC (2:30 p.m. EST), moderate to heavy rains were moving toward Port Hedland, in advance of the center of Tropical Storm 10S.

TD 10S is moving southwest and is forecast to move parallel to the western coastline of Australia. The storm is expected to strengthen to hurricane force but not threaten land areas.

Im Focus: Scientists present new observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...

Im Focus: Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.

"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...

Im Focus: New soft coral species discovered in Panama

A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.

Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
