NASA sees heavy rains in Tropical Storm Bingiza, possibly headed for second landfall

18.02.2011
NASA satellite data indicates that Bingiza is still maintaining tropical storm intensity and carrying heavy rainfall over the Mozambique Channel as it prepares for its second landfall in Madagascar.

Deadly Tropical Cyclone Bingiza, which crossed over northern Madagascar three days ago, has continued to affect Madagascar while moving along Madagascar's west coast. Bingiza had weakened from a powerful category 3 tropical cyclone with sustained winds of 100 kts (~115 mph/185 kmh) to tropical storm force winds of about 35 kts (~40 mph/65 kmh) when the Tropical Rainfall Measuring Mission (TRMM) satellite passed almost directly overhead on February 16, 2011 at 1911 UTC (2:11 p.m. EST).

TRMM data was used to create an image of Bingiza's rainfall. The analysis used TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data. At that time, Bingiza was approaching Madagascar from the Mozambique Channel with additional moderate to heavy rainfall (over 2 inches/50 mm per hour). Extremely heavy rainfall was revealed to be located in a small area near Bingiza's center of circulation.

On February 17 at 0900 UTC (4 a.m. EST), Bingiza's maximum sustained winds were near 40 knots (46 mph/74 kmh) with higher gusts. It was about 220 nautical miles west-southwest of Antananarivo, Madagascar, near 21.0 South and 43.7 East. Bingiza was moving south at 7 knots (8 mph/13 kmh).

Multispectral satellite imagery showed that Bingiza still has strong bands of thunderstorms wrapping around it from the northwest into the southeast quadrant. The low-level center of circulation is partially exposed to outside winds, however. Exposure to outside winds leaves the storm vulnerable for weakening.

A low to mid-level ridge (elongated area of high pressure) located to the northeast of Bingiza is what's guiding it southward, and then it is forecast to track along the ridge and move southeastward in the next day taking it near or over land. Some models show that the storm may meander and remain over water while others take it inland. Whether it stays near the coast or moves inland, Bingiza is still forecast to weaken and is expected to dissipate by the weekend.

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...
