Philippe was still a tropical storm when the TRMM satellite passed above on October 3, 2011 at 1806 UTC (2:06 p.m. EDT) but the National Hurricane Center (NHC) predicts that the storm may become a hurricane in a couple days. TRMM's TMI and Precipitation Radar (PR) data showed that bands of powerful convective thunderstorms were still dropping rain at a rate of over 50mm/hr (~2 inches) in the southeastern quadrant of the storm because wind shear was pushing it there.
This TRMM image shows the heaviest rainfall in Philippe (2 inches/50 mm per hour) in red, falling in its southeastern quadrant. Moderate to light rainfall appears in green and blue, falling at a rate between .78 to 1.57 inches (20 to 40 mm) per hour. Credit: NASA/SSAI, Hal Pierce
Philippe has been battling wind shear from the northwest, as the coldest cloud tops, heaviest rain and frequent lightning have remained on the southeastern side of the storm for the last two days.
At 11 a.m. EDT on Oct. 4, Tropical Storm Philippe's maximum sustained winds were still near 65 mph (as they were when TRMM flew overhead on Oct. 3). However, the National Hurricane Center noted that Philippe may still strengthen and reach hurricane status in the next couple of days. Philippe is still a small storm, about 170 miles in diameter, as tropical storm-force winds extend out 85 miles from the center.
Philippe's center was about 530 miles (850 km) south-southeast of Bermuda, near latitude 25.3 north and longitude 61.3 west. Philippe is moving toward the northwest near 6 mph (9 kmh), but is expected to speed up and turn to the northeast on Thursday, Oct. 6 because of a strong mid-latitude trough approaching it.Text credit: Rob Gutro

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...
