NASA Satellite Sees Tropical Cyclone Gillian Return to Remnant Low Status


NASA's Aqua satellite captured a visible image of Tropical Cyclone Gillian's remnants in the southern Arafura Sea today, as it passes north of Australia's "Top End."

During the week of March 10, Tropical Cyclone Gillian formed in the northern Gulf of Carpentaria and made a brief landfall on the Western Cape York Peninsula, weakening to a remnant low.

The MODIS instrument aboard NASA's Aqua satellite captured this visible image of Gilian's remnants moving through the Arafura Sea, north of Top End, Northern Territory on March 17, 2014.

After re-emerging in the Gulf, Gillian became a tropical storm again and by March 17 had again weakened to a remnant low as it exited the Gulf and moved into the Arafura Sea.

The MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite captured a visible image of Gillian's remnants moving through the Arafura Sea, north of Top End, Northern Territory at 04:05 UTC/12:05 a.m. EDT on March 17, 2014.

According to the Joint Typhoon Warning Center, an image from NOAA's NOAA-19 polar orbiting satellite on March 17 at 02:50 UTC showed that the low-level circulation center of Gillian is ill-defined and that there is weak banding of thunderstorms around it.

The system is also surrounded by dry air, which is further sapping the storm's ability to generate the thunderstorms that make up the tropical cyclone. Satellite data from the Advanced Scatterometer (ASCAT) that flies aboard the EUMETSAT METOP-A satellite showed that 10 to 15 knot/11.5 to 17.2 mph/ 18.5 to 27.7 kph winds were only seen over the western side of the storm. 

On Monday, March 17. 2014, the Australian Bureau of Meteorology noted that Ex-Tropical Cyclone Gillian was located at 10 pm CST (local time, Darwin) near 10.2 south and 134.2 east, about 127.4 miles/205 km north of Maningrida and 127.4 miles/205 km east northeast of Croker Island.  Gillian's remnants are moving west at 8.6 knots/9.9 mph//16 km per hour.

ABM expects Ex-Tropical Cyclone Gillian to continue moving to the west and is forecast to remain well to the north of the Top End coast. The north coast of the Northern Territory is not expected to receive gale-force winds.

Satellite data shows that rainfall and convection has been pushed to the western side of the center of circulation. Because of the wind shear, the ABM does not expect strengthening.

Im Focus: Kick-off for a new era of precision astronomy

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.

As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...

Im Focus: Locusts at the wheel: University of Graz investigates collision detector inspired by insect eyes

Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.

In cooperation with the Center for Nano-Optics of Georgia State University in Atlanta (USA), scientists of the Laboratory for Attosecond Physics of the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität have made simulations of the processes that happen when a layer of carbon atoms is irradiated with strong laser light.

Electrons hit by strong laser pulses change their location on ultrashort timescales, i.e. within a couple of attoseconds (1 as = 10 to the minus 18 sec). In...
