Two NASA Satellites See System 92B Headed North in Bay of Bengal

23.05.2014

NASA's Aqua and TRMM satellites captured radar and infrared data on developing tropical low pressure area System 92B as it now makes it way north through the Bay of Bengal.

On May 22 at 00:51 UTC, NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission (TRMM) satellite passed over System 92B as it was dropping heavy rainfall over the Bay of Bengal.


In this TRMM 3-D image of System 92B from May 21, some powerful convective storm tops were reaching heights of almost 17 km (about 10.5 miles).

TRMM's Precipitation Radar (PR) revealed that rain was falling at the extreme rate of over 191 mm (about 7.5 inches) per hour in powerful convective storms in the center of the Bay of Bengal well to the east of India.

At NASA's Goddard Space Flight Center in Greenbelt, Maryland, TRMM's Precipitation Radar data were also used to construct a simulated 3-D view of 92B's rainfall structure looking toward the east from India.

TRMM PR pulled away a veil of clouds and revealed that some powerful convective storm tops were reaching heights of almost 17 km (about 10.5 miles). The extreme rainfall in this area was returning radar reflectivity values of over 53.7 dBZ to the TRMM satellite.

On May 22 at 7:11 UTC/3:11 a.m. EDT, NASA's Aqua satellite passed over System 92B and the Atmospheric Infrared Sounder or AIRS instrument captured infrared data on the low's cloud tops. Satellite imagery shows that the low-level circulation center is large and poorly defined with flaring and fragmented deep convection.

The data showed two areas where thunderstorms had high cloud tops and very cold temperatures near -63F/-52C. Thunderstorms that high into the troposphere have been found to generate heavy rainfall. The areas of strong thunderstorms were north and west of the center of circulation.

By 08:00 UTC/4 a.m. EDT, the Joint Typhoon Warning Center estimated that System 92B had maximum sustained winds between 25 to 30 knots (28.7 to 34.5 mph/46.3 to 55.5 kph). Metsat satellite imagery indicated that the circulation center is located near 17.0 north latitude and 92.1 east longitude in the Bay of Bengal, about 315 nautical miles south of Chittagong, Bangladesh.

System 92B is moving north at 5 knots (5.7 mph/9.2 kph). Computer models vary on the development of the tropical low pressure area, but do expect it to continue drifting to the north and north-northwest.

The Joint Typhoon Warning Center noted that System 92B's potential for the development of a significant tropical cyclone within the next 24 hours remains high.

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,...
