NASA sees Tropical Storm Sanvu continue to intensify

24.05.2012
Two NASA satellites have provided infrared and rainfall data that has shown Tropical Storm Sanvu continues to intensify as it heads toward Iwo To, Japan.

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite has scanned rainfall rates, and NASA's Aqua satellite has provided a look at cloud temperatures which indicates where the strongest thunderstorms and heaviest rainfall is occurring.

The TRMM satellite saw the intensifying storm on May 22, 2012 at 1535 UTC when wind speeds had reached to over 45 knots (~52 mph). Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that Sanvu had a very large area of heavy rainfall wrapping around the northeastern side. TRMM's PR also shows that the highest convective storm towers, reaching to heights above 16km (~9.9 miles), were in a feeder band on the southeastern side.

On May 23, the TRMM passed over Sanvu again after it had strengthened further, and captured more data. That data was used to create another 3-D analysis at NASA's Goddard Space Flight Center in Greenbelt, Md. The 3-D image created from TRMM PR data revealed that an eye was almost formed indicating that Sanvu may soon be a typhoon. Several towers in the forming eye wall extend to heights above 16km (~9.94 miles). These towers contain the heaviest rains and act to energize the core of the storm.

On May 23 at 1500 UTC (11 a.m. EDT), Tropical Storm Sanvu has maximum sustained winds near 60 knots (69 mph/111 kph). It was located about 450 nautical miles south-southwest of Iwo To, Japan and moving toward the island in a northwesterly direction at 10 knots (11.5 mph/18.5 kph). Sanvu's center is near 17.8 North and 139.2 East.

Infrared satellite imagery from NASA's Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite showed that Sanvu's feeder bands were mostly on the eastern side of the center of circulation and have become more tightly wrapped around the center. Those thunderstorms within the feeder bands have also strengthened. The strongest storms have a cloud top temperature colder than -63F (-52C) indicating they are high in the troposphere and powerful.

Sanvu is predicted to intensify further and become the first western Pacific typhoon of 2012. One factor that is helping Sanvu continue to intensify is the warm sea surface temperatures at 86 degrees Fahrenheit (30 Celsius).

The current forecast track takes it just east of Iwo To and Chichi Jima, which may experience typhoon conditions on May 25 and 26, respectively.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

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,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

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...

Im Focus: Circular RNA linked to brain function

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...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

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...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

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...
