Tropical Depression 21E strengthened overnight on Oct. 30 and by Halloween morning, Tropical Storm Vance was haunting the waters of the Eastern Pacific Ocean. In a false-colored infrared image from NASA's Terra satellite on Oct. 31, the strong thunderstorms around the center resemble a pumpkin.
Tropical Depression 21E formed on Oct. 30 after struggling for days as a low pressure area. Just a day later it strengthened into a tropical storm and was renamed Vance.
NASA's Terra satellite passed over Vance on October 31 at 4:55 UTC (12:55 a.m. EDT) – the witching hour – and the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Terra captured infrared data.
That infrared data was false-colored when the image was created. High, strong thunderstorms with cold cloud top temperatures that circled the center were false-colored in an orange-red color, and resembled the shape of a pumpkin with a stem!
At 5 a.m. EDT, Tropical Storm Vance's maximum sustained winds were near 45 mph (75 kph) and is expected to strengthen gradually. Vance was centered near latitude 10.5 north and longitude 101.0 west.
That's about 450 miles (720 km) south of Acapulco, Mexico. Vance is moving toward the west-southwest near 3 mph (6 kph) and is forecast to turn to the west and west-northwest on Nov. 1.
National Hurricane Center Forecaster Dan Brown noted that Vance's center was near the southern edge of the large mass of deep convection due to moderate south-southwesterly shear.
The shear and some dry low- to mid-level air are expected to continue to affect the tropical cyclone during the next 12 to 24 hours, and only gradual strengthening is expected during that time.
Most of the intensity guidance shows Vance becoming a hurricane in 2 to 3 days.

Climate change: In their old age, trees still accumulate large quantities of carbon

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...
