Tropical Cyclone Bavi's convection and developing thunderstorms have been waning because of wind shear, and NASA's Aqua satellite provided an infrared look at the weakening storm.
The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite revealed warming infrared temperature data of Tropical Cyclone Bavi's clouds on March 16 at 16:47 UTC (10:47 a.m. EDT).
At 0900 UTC (5 a.m. EDT) on March 17, 2015 the Joint Typhoon Warning Center (JTWC) noted that "Recent animated enhanced infrared satellite imagery showed the system is stripped of any significant deep convection."
That's as a result of moderate to strong (20 to 30 knot/23 to 34.5 mph/37 to 55.5 kph) southwesterly vertical wind shear.
The imagery showed a ragged low-level circulation center and cloud top temperatures had warmed over the previous 24 hours. Warming cloud tops indicate that the cloud tops are dropping and the storms are weakening.
Bavi has weakened to a depression with maximum sustained winds near 30 knots (35 mph/55 kph). Bavi was centered near 15.6 north latitude and134.5 east longitude, about 784 nautical miles (902 miles/1,453 km) east of Manila, Philippines. Bavi was moving to the west-northwest at 8 knots (9.2 mph/14.8 kph).
Bavi is moving to the west, tracking along the southern edge of a sub-tropical ridge (elongated area) of high pressure to the north. The JTWC expects Bavi to dissipate in the next day or two.

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...
