Three Days of NASA Infrared Images Show System 92S Tropically Developing

28.02.2012
NASA satellites have been watching the low pressure area called System 92S for days, and infrared imagery from NASA's Aqua satellite showed cloud temperatures were cooling, indicating the storm was getting more organized as it moved over northern Madagascar. Now it may be headed for landfall in Mozambique.

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured infrared imagery on developing System 92S as it moved from the Southern Indian Ocean, west across northern Madagascar and into the Mozambique Channel.


The AIRS instrument on NASA's Aqua satellite captured infrared imagery on developing System 92S in the Mozambique Channel (Indian Ocean). On February 25 at 0941 UTC, System 92S was moving west toward Madagascar. By February 26 at 10:23 UTC System 92S was over northwestern Madagascar. On February 27 at 1105 UTC had moved into the Mozambique Channel and appeared to be heading for a landfall in Mozambique.

On February 25 at 0941 UTC, System 92S appeared as a rounded low pressure area with the strongest storms (and highest, coldest cloud tops on AIRS infrared imagery) south of the center of circulation. It was still in the open waters of the Southern Indian Ocean and was moving west toward Madagascar. By February 26 at 10:23 UTC System 92S was raining on northern Madagascar.

On February 27 at 1105 UTC had moved into the Mozambique Channel and appeared to be heading for a landfall in Mozambique. On the 27th, the strongest thunderstorms and coldest cloud tops appeared in two areas, north and east of the storm's center.

On February 27, the center of System 92S was located in the Mozambique Channel, near 13.5 South and 48.5 East, about 345 nautical miles north-northeast of Antananarivo, Madagascar. AIRS infrared imagery indicated that the low had weakened because of its interaction with land, as it moved over northern Madagascar.

Now that the center of System 92S is over the warm waters of the Mozambique Channel, it is expected to redevelop quickly. The area of strong thunderstorms east of center, as seen on AIRS imagery is a band of thunderstorms.

The Joint Typhoon Warning Center gives this system a high chance for developing further into a tropical cyclone in the next 24 hours.

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...
