NASA Sees Eastern Pacific Get First Tropical Storm: Alvin

17.05.2013
NASA’s Aqua satellite and NOAA’s GOES-15 satellite captured imagery of the Eastern Pacific Ocean’s first named tropical storm, Alvin. Aqua and GOES-15 provided imagery of Alvin that provided a look at the overall storm and the temperatures of its cloud tops.

NASA’s Aqua satellite flew over Tropical Storm Alvin just as it reached tropical storm status on May 15 at 2047 UTC (4:47 p.m. EDT). The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard Aqua captured an infrared image of the storm that showed bands of thunderstorms on the tropical storm’s western side were wrapping into the low-level center. Those bands of thunderstorms became more organized and more tightly wrapped by May 16 as the storm strengthened further.

AIRS data is infrared and gives an indication of temperature. With respect to tropical cyclones, AIRS provides temperatures of cloud tops and surrounding ocean surface temperatures, two factors important in determining the strength of a storm and what may happen with it. Cold cloud top temperatures, such as those seen in some of the bands around Alvin were near -62 Fahrenheit (-52 Celsius) and are indicative of strong uplift that can create strong, high thunderstorms with heavy rain potential.

NOAA’s GOES-15 satellite captured a near-infrared view of Tropical Storm Alvin on May 16 at 1200 UTC (8 a.m. EDT) as it continued moving west and away from Mexico. This near-infrared view showed that Alvin had become more tightly wrapped and more organized. According to the National Hurricane Center, satellite imagery of Alvin shows very deep convection resembling a central dense overcast, but noted that the low-level center is displaced a fair distance west of the strongest convection (rising air that creates thunderstorms that make up the tropical cyclone).

AIRS imagery is produced at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. and GOES imagery is created at NASA’s GOES Project, located at NASA’s Goddard Space Flight Center in Greenbelt, Md.

At 5 a.m. EDT on May 15, Alvin had maximum sustained winds near 50 mph (85 kph). It was located far from land, about 705 miles (1,135 km) south-southwest of Manzanillo, Mexico, near 9.1 north latitude and 106.9 west longitude. Alvin was moving to the west-northwest at 10 mph (17 kph) and had a minimum central pressure near 1003 millibars. Twenty four hours before, Alvin’s central pressure was near 1006 millibars. A drop in pressure indicates a strengthening low pressure area.

The National Hurricane Center noted that Alvin will be moving through warm waters over the next couple of days in the Eastern Pacific Ocean and is expected to reach hurricane strength by early on May 18 before weakening over the weekend of May 18 and 19.

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...
