NASA analyzes rainfall in Tropical Cyclone Joalane

09.04.2015

NASA and the Japan Aerospace Exploration Agency's GPM satellite provided scientists with a look "under the hood" of Tropical Cyclone Joalane's clouds at the rate in which rain was falling throughout the storm.

The Global Precipitation Measurement or GPM core observatory satellite flew over intensifying cyclone Joalane in the South Indian Ocean on April 6, 2015 at 0406 UTC (12:06 a.m. EDT). GPM's Microwave Imager (GMI) found that intense convective thunderstorms within Joalane were dropping rain at a rate of over 63 mm (2.5 inches) per hour.


On April 8 at 09:35 UTC (5:35 a.m. EDT) NASA's Aqua satellite captured this visible light image of Tropical Cyclone Joalane that showed the storm maintained its eye.

Cyclone Joalane was located northeast of Mauritius at the time of that GPM pass. At NASA's Goddard Space Flight Center in Greenbelt, Maryland a 3-D view of Joalane's vertical precipitation structure was constructed using GPM's Radar (Ku Band) data.

This cross section showed that several towering thunderstorms near Joalane's center were reaching heights of over 15 km (9.3 miles). A few storm tops in a strong rain band south of Joalane's center were found reaching even higher to altitudes of 17.4 km (10.8 miles).

Two days later, on April 8 at 09:35 UTC (5:35 a.m. EDT) the MODIS instrument that flies aboard NASA's Aqua satellite captured a visible light image of Tropical Cyclone Joalane that showed the storm maintained an eye that it developed the previous day. Bands of thunderstorms wrapped into the center of circulation. The largest, thickest band of thunderstorms appeared on the eastern side of the center.

At 1500 UTC (11 a.m. EDT) on April 8, 2015, Tropical Cyclone Joalane's maximum sustained winds were near 90 knots (103.5 mph/166.7 kph). It was centered near 15.6 south and 64.9 east, about 624 nautical miles (718.1 miles/1,156 km) east-northeast of St. Denis.

Joalane is moving to the southeast at 9 knots (10.3 mph/16.6 kph). At that time, there were no tropical cyclone warnings in effect for Rodrigues Island.

Tropical Cyclone Joalane has intensified and the Joint Typhoon Warning Center forecast a southeastern track through the Southern Indian Ocean. Joalane is expected to weaken to a tropical storm by April 13.

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,...
