NASA satellite tracks soaking System 91S in western Australia

20.12.2010
NASA's Aqua satellite captured a series of images from its Atmospheric Infrared Sounder (AIRS) instrument over the last two days and saw the low pressure area known as System 91S make landfall in Australia. System 91S may not have become a tropical depression, but it's dropping heavy rainfall in Western Australia.

NASA's AIRS infrared instrument showed System 91S's center making landfall on Dec. 16 at 0647 UTC (1:47 a.m. EST) near the town of Carnavon in Western Australia. At that time, there was a large area of strong thunderstorms around the center of circulation, and the cloud tops appeared on the infrared imagery to be as cold as or colder than -63 degrees Fahrenheit.

Accompanying those thunderstorms was heavy rainfall. When NASA's Aqua satellite passed over Western Australia again at 17:41 UTC (12:41 p.m. EST) on Dec. 16, the center of System 91S had already made landfall and was moving inland. It still contained a large area of strong thunderstorms and heavy rainfall, although most were in the western and southern side of the low.

On Friday, December 17 (Eastern Time) local radar in Western Australia showed that the remnants of the low were bringing rainfall to inland areas of the region. At 11:05 a.m. EST (12:05 a.m. on Saturday, December 18 WST local time) rain was falling in an oval shaped-area over the towns of Meekatharra, Peak Hill, Reedy, Wiluna and Cue along route 95, also known as the Great Northern Highway. North of those towns, rain was also falling in Collier Range National Park.

At 12:05 a.m. on Saturday, December 18 WST local time, the Meekatharra Airport also reported a temperature of 63 degrees Fahrenheit with winds from the east-southeast at 20 mph, and a minimum central pressure of 29.60 inches.

The Australian Government Bureau of Meteorology (AGBM) in Western Australia issued a severe weather warning about the remnants of System 91S. From 9am Thursday (local time) to 9 a.m. local time Friday, Carnarvon Airport reported 8.01 inches (205mm) and Shark Bay Airport 4.2 inches (107 mm) of rain.

The AGBM noted that System 91S's center was near 23 South latitude and 112 East longitude at 7 p.m. WST (6 a.m. EST), which is about 125 miles (200 kilometers) southwest of Exmouth. Exmouth is a town on the tip of the North West Cape in Western Australia.

At that time, heavy rain was occurring in a band southeast of the low's center, and AGBM forecasters expect significant rainfall over parts of the Gascoyne, extending east into the northern Goldfields and south to far northern parts of the Central West during the overnight hours (local time). That heavy rainfall is likely to cause flash flooding and rising streams. As a result, a Flood Watch was issued for streams between Carnarvon and Kalbarri, including the Murchison River Catchment.

System 91S's remnants were moving slowly south-southeast and are expected to move toward the southwest this weekend.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
