NASA Satellite Image Sees Cyclone Victoria Looking like a “J” from Space

12.04.2013
Tropical Cyclone Victoria (Southern Indian Ocean)

When NASA’s Aqua satellite flew over Cyclone Victoria in the Southern Indian Ocean it captured a visible image of the storm and it appeared to look like the letter “J.” A band of thunderstorms wrapping into the center from the east of low-level center of circulation extended north, creating the appearance of the letter.

NASA's Aqua satellite passed over Tropical Cyclone Victoria on April 11 at 0320 UTC (April 10 at 11:20 p.m. EDT). The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard Aqua captured the visible image that showed strong thunderstorms around the center of circulation and in a band of thunderstorms wrapping around the eastern side of the storm.

On April 11 at 1500 UTC (11 a.m. EDT), Cyclone Victoria had maximum sustained winds near 50 knots (57.5 mph/92.6 kph). It was centered near 20.5 south latitude and 105.3 east longitude, about 530 nautical miles (610 miles/981.6 km) west-northwest of Learmonth, Australia. Victoria is moving to the south-southeast at 14 knots (16.1 mph/25.9 kph).

Wind shear is affecting Victoria, pushing the strongest convection (rising air that forms the thunderstorms that make up the tropical storm) and thunderstorms southeast of the center. The Joint Typhoon Warning Center forecasters noted that the wind shear is a result of a powerful jet stream located southwest of the cyclone. The wind shear is expected to continue increasing as Victoria tracks southeast, and sea surface temperatures will drop below the 80 degree Fahrenheit (26.6 Celsius) threshold needed to maintain a tropical cyclone. Those two factors are expected to weaken Victoria very quickly in the next day or two.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
