Powerful Tropical Cyclone Hellen rapidly weakened after hitting northwestern Madagascar but Hellen's remnants have recently started to show signs of life. The TRMM satellite flew over these remnants in the Mozambique Channel on April 2, 2014 at 0143 UTC.
A rainfall analysis using the Tropical Rainfall Measuring Mission's (TRMM) Microwave Imager (TMI) and Precipitation Radar (PR) instruments found that some strong convective thunderstorms had developed in the area.
It was revealed by TRMM PR data that rain was falling at a rate of over 75 mm/~ 3 inches in a few locations.
TRMM's Precipitation Radar (PR) data were used to create a 3-D image that showed the structure in the convective thunderstorms near the center of Hellen's remnants.
The 3-D view showed that a few of these tall thunderstorms were reaching heights of over 16 km/9.9 miles.
At 1800 UTC/2:00 p.m. EDT on April 1, the center of Hellen's remnants were located near 18.3 south and 42.3 east, about 271 nautical miles/311.9 miles/501.9 km west of Antananarivo, Madagascar.
Maximum sustained winds were estimated as high as 25 knots/28.7 mph/46.3 kph, and minimum sea level pressure was near 1004 millibars. The low-level circulation center appeared slightly elongated and the convection and thunderstorm development is disorganized.
The Joint Typhoon Warning Center expects the remnant low to move on a westward track toward Mozambique over the next couple of days. The system has a low chance of regenerating in the next 24 hours.

Climate change: In their old age, trees still accumulate large quantities of carbon

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
