NASA Sees Cyclone Gino Wind Up to Wind Down Later

13.02.2013
NASA's Aqua satellite passed over Cyclone Gino as the storm continues to wind up in the southern Indian Ocean, consolidating and strengthening. Infrared data shows the storm has strengthened but it is headed for cooler waters which will weaken it in coming days.

On Feb. 12 at 0841 UTC, NASA Atmospheric Infrared Sounder (AIRS) instrument that flies aboard the Aqua satellite captured infrared imagery of Cyclone Gino that showed the storm developed a large area of very cold, high cloud top temperatures around its center indicating powerful thunderstorms.

Cloud top temperatures were as cold as -63 Fahrenheit (-52 Celsius) indicating strong storms that have the capability to produce heavy rainfall. The AIRS imagery also suggests a ragged eye had formed.

On Feb. 12 at 1500 UTC (10 a.m. EST), Cyclone Gino's maximum sustained winds had increased to 75 knots (86.3 mph/138.9 kph) making the storm a category one hurricane. Gino was centered near 17.1 south latitude and 79.5 east longitude, about 700 nautical miles (805.5 miles/1,296 km) southeast of Diego Garcia.

Gino has been moving to the south-southwest at 10 knots (11.5 mph/18.5 kph), around the northwestern edge of a subtropical ridge (elongated area) of high pressure.

AIRS data shows that the sea surface temperatures around Gino are currently favorable for further development because they're around a warm 28 degrees Celsius (82.4 Fahrenheit). However, as Gino moves further south-southwest, those sea surface temperatures will drop, making it more difficult for the tropical cyclone to maintain intensity.

In addition, wind shear is expected to increase over the next three days as Gino moves further south. The Joint Typhoon Warning Center expects Gino to transition to a cold core low pressure area by Feb. 15.

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...
