NASA sees Tropical Cyclone Nathan over Australia's Top End

24.03.2015

Tropical Cyclone Nathan moved from Queensland, Australia west across the Gulf Carpentaria and is now crossing The Top End. NASA's Aqua and Terra satellite provided a day-to-day look at Nathan's western journey.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument flies aboard two NASA satellites: Terra and Aqua. MODIS provided images from each of those satellites over the course of three days that showed Nathan's western movement and second landfall in the Northern Territory of Australia.


On March 23 at 04:35 UTC, NASA's Aqua satellite captured this image of Tropical Cyclone Nathan over the Top End of the Northern Territory, Australia.

On Saturday, March 21 at 04:50 UTC (12:50 a.m. EDT) MODIS aboard NASA's Aqua satellite captured Tropical Cyclone Nathan moving west through the Gulf of Carpentaria. On March 22 at 01:05 UTC (March 21 at 9:05 p.m. EDT) the MODIS instrument aboard NASA's Terra satellite saw Tropical Cyclone Nathan making landfall near Arnheim Land, in the Northern Territory of Australia.

On March 23 at 04:35 UTC (12:35 a.m. EDT), the MODIS instrument aboard NASA's Aqua satellite captured a visible mage of Tropical Cyclone Nathan over the Top End of the Northern Territory, Australia. The Top End of northern Australia is the northernmost section of the Northern Territory.

At 09:00 UTC (5 a.m. EDT), Nathan's maximum sustained winds were near 65 knots (75 mph/120.4 kph), making it a category one hurricane. Nathan's center was located near 11.4 south and 134.1 east, about 210 nautical miles (241 miles/389 km) east-northeast of Darwin, Australia. Nathan was moving west at 6 knots (7 mph/11 kph).

On March 23, the Australian Bureau of Meteorology has posted Warnings and watches for the Northern Territory. The Tropical Cyclone Warning is in effect from Milingimbi to Cape Don and Point Stuart, including Croker Island, Goulburn Island, Gunbalanya, Jabiru and Maningrida. A Tropical Cyclone Watch is in effect from Cape Hotham to Point Stuart and Cape Don to Milikapiti and eastern Melville Island.

The Joint Typhoon Warning Center using animated enhanced infrared satellite imagery, noted that Nathan had maintained overall convective signature as it drifted just offshore of the Northern Territory.

Nathan is tracking along the northern edge of a deep-layered subtropical ridge (elongated area of high pressure) to the south, over central Australia. Later on March 23, the ridge will weaken as a mid-latitude trough (elongated area) of low pressure from the southwest approaches, causing Nathan to move southwestward toward Darwin before returning on a westward track.

The Joint Typhoon Warning Center (JTWC) expects Nathan to continue tracking to the west over the next several days. JTWC's forecast track takes the center of Nathan just south of Darwin on March 25 around 0600 UTC (2 a.m. EDT) on its way into the Southern Indian Ocean.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
