NASA's infrared satellite imagery sees Tropical Storm Darby form quickly

24.06.2010
The fifth tropical depression of the Eastern Pacific Ocean hurricane season developed and quickly strengthened into Tropical Storm Darby during the early morning hours of June 23. NASA's Aqua satellite captured a large area of strong convection that indicated that speedy strengthening.

Darby formed off the western Mexico coast south of the Gulf of Tehuantepec. At 5 p.m. EDT on June 22 Darby was located about 540 miles south-southeast of Salina Cruz, Mexico. That's near 11.5 North and 94.0 West.

Earlier on June 22, at 19:23 UTC (3:23 p.m. EDT), NASA's Aqua satellite flew over the low pressure area that became classified as Tropical Depression Darby and provided forecasters with a look at the convection happening in the storm. Infrared satellite imagery from the Atmospheric Infrared Sounder (AIRS) instrument indicated a large area of strong convection to the north of Darby's center where cloud tops were as cold as or colder than -63 degrees Fahrenheit. Infrared satellite data is helpful to forecasters in determining the convection (rapidly rising air that condenses and forms clouds and thunderstorms). Strong convection, like that seen in Darby is indicative of a strengthening tropical cyclone.

Darby's maximum sustained winds had increased to 40 mph with higher gusts by 5 a.m. EDT on June 23. Tropical storm-force winds extend outward up to 50 miles to the west of the center. Additional strengthening is also expected in the next 48 hours. Estimated minimum central pressure is 1005 millibars.

Darby is moving to the northwest near 9 mph, but is expected to turn toward the west-northwest and then west over the next day. Residents from Acapulco north to Manzanillo, Mexico should watch the track of Darby over the next several days.

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...
