NASA's Aqua satellite spots Tropical Cyclone Bansi intensifying quickly

13.01.2015

NASA's Aqua satellite passed over Tropical Cyclone Bansi on January 12 as it was intensifying rapidly and saw a cloud-covered eye in the storm's center. Bansi has triggered warnings for the island of Mauritius and is expected to continue intensifying while passing it.

On Sunday, January 11, Tropical Cyclone Bansi formed north of La Reunion Island in the Southern Indian Ocean and triggered two alerts. A tropical cyclone warning class I was posted at Mauritius, and a Yellow pre-alert went into effect for La Reunion Island. At 0900 UTC (4 a.m. EST) Tropical Cyclone Bansi (formerly System 92S) was located about 254 nautical miles north of St Denis, La Reunion Island. It was slowly moving to the east-southeast and had maximum sustained winds near 35 knots (40 mph/62 kph).

On January 11 at 06:40 UTC (1:40 a.m. EST) the MODIS instrument aboard NASA's Terra satellite captured an image of Tropical Cyclone Bansi. The MODIS image showed strong thunderstorms tightly wrapped around the center, and a large, wide band of thunderstorms in the storm's eastern quadrant spiraling around the storm and into the center from the west.

By January 12 at 10:10 UTC (5:10 a.m. EST) when the MODIS instrument aboard NASA's Aqua satellite passed overhead, the storm had rapidly consolidated and the bands of thunderstorms circling the center had expanded. Bands of thunderstorms spiraling around the storm wrapped around the storm from the northwest to the southeast and finally wrapping into the center from the west. The eye of the storm appeared covered by high clouds.

In Mauritius, the warnings on January 12 were changed to a tropical cyclone warning class 2. La Reunion, which lies to the southwest of Mauritius and is farther from the storm remained on Yellow pre-alert.

In less than 24 hours after it formed, Bansi strengthened from a minimal tropical storm into a major hurricane (Category 3) with maximum sustained winds. A Category three hurricane on the Saffir-Simpson wind scale has sustained winds from 111 to 129 mph (96 to 112 knots/178 to 208 kph).

At 0900 UTC (4 a.m. EST) on January 12, Bansi had maximum sustained winds near 100 knots (115.1. mph/185.2 kph). Bansi was centered near 17.2 south latitude and 56.1 east longitude, about 191 nautical miles (219.8 miles/ 353.7 km) north-northwest of Port Louis, Mauritius, has tracked eastward at 7 knots (8.0 mph/12.9 kph).

The Joint Typhoon Warning Center noted that Bansi continued to rapidly intensify as a result of passage over warm water, low vertical wind shear, and outflow aloft. A tropical cyclone needs good outflow (where winds spread out at the top of the hurricane) to maintain strength. Outflow means that air spreads out over the top of the storm assisting in its development. When outflow is weakened, the storm weakens.

Bansi is moving eastward along the southern edge of a near-equatorial ridge (elongated area) of high pressure. Bansi is forecast to continue moving to the east then southeast while strengthening to 125 knots before running into atmospheric conditions and cooler waters that will weaken it.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
