The National Hurricane Center (NHC) upgraded an area of disturbed weather in the Caribbean to tropical depression eighteen and then to tropical storm Rina on October 23, 2011. The TRMM satellite flew over the forming tropical cyclone on October 23, 2011 at 1728 UTC (1:28 p.m. EDT).
This infrared image of the eastern half of Tropical Storm Rina was taken on Oct. 24 at 2:47 a.m. EDT from the AIRS instrument on NASA's Aqua satellite. It shows a very large area of strong convection and thunderstorms around the center (purple) of circulation. Cloud top temperatures were colder than -63F (-52C) in that area, indicating strong thunderstorms and heavy rainfall. Credit: NASA/JPL, Ed Olsen
At 11 a.m. EDT on Oct. 24, Rina's maximum sustained winds were near 45 mph (75 kmh). Those tropical storm-force winds extend out 85 miles (140 km) from the center, making Rina a small tropical storm over 170 miles in diameter.
There are a couple of factors steering Rina through the Caribbean Sea. In the mid-level of the atmosphere there's a ridge (elongated area) of high pressure building over the northern Gulf of Mexico, which is expected to turn Rina to the west-northwest. The NHC noted that as the ridge moves eastward in a couple of days, it will take Rina northwest, then northward. The NHC expects Rina to become a hurricane tomorrow.

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...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
