Cyclone Wilma's eye catches attention of NASA satellites

26.01.2011
Wilma caught the eye of NASA. NASA's Aqua satellite captured visible and infrared images of Cyclone Wilma in the Southwestern Pacific Ocean and her eye was clearly visible from space.

On January 25 at 00:59 UTC (8:59 p.m. EST on Jan. 24), the Atmospheric Infrared Sounder (AIRS) instrument captured data that was used to create infrared and visible images at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The images showed Cyclone Wilma had strengthened overnight and now has a visible eye.


Tropical cyclone Wilma was seen by the TRMM satellite shortly after attaining hurricane intensity on Jan. 24, 2011, at 2128 UTC. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches (20 and 40 mm) per hour. Credit: NASA/SSAI, Hal Pierce

AIRS Infrared imagery showed strong, very cold thunderstorm cloud tops around Wilma's center of circulation. The cloud tops were as cold as or colder than -63 Fahrenheit (-52 Celsius) indicating strong convection (rapidly rising air that creates the thunderstorms that power a tropical cyclone). Animated infrared satellite imagery showed a 25 nautical mile (29 mile/46 km) diameter ragged eye with tightly-curved banding of thunderstorms wrapping into the center.

AIRS instrument data also showed what appears to be a large "tail" from Wilma's center, stretching several hundred miles (kilometers) to the northeast of the storm's center.

Tropical cyclone Wilma was also seen by the Tropical Rainfall Measuring Mission (TRMM) satellite shortly after attaining hurricane intensity on January 24, 2011 at 2128 UTC 2:28 p.m. EST). The system had mostly moderate rainfall, falling at rates between .78 to 1.57 inches (20 and 40 mm) per hour. The TRMM satellite is managed by both NASA and JAXA, and TRMM data and imagery was created at NASA's Goddard Space Flight Center in Greenbelt, Md.

On January 25 at 0900 UTC (4 a.m. EST), Tropical Cyclone Wilma had maximum sustained winds near 85 knots (97 mph/157 km/hr). It was located about 360 nautical miles southeast of Nadi, Fiji near 22.0 South and 178.2 West. It was moving southwestward near 24 knots (27 mph/ 44 km/hr).

A Tropical Cyclone Warning is in force for areas of Tonga and for areas of Fiji. On its projected path, Tropical Cyclone Wilma is expected to pass about 124 miles (200 km) south-southeast of Ono-i-lau by midnight local time tonight.

Republic of the Fiji Islands is an island nation in Melanesia in the South Pacific Ocean about 1,243 miles (2,000 km) northeast of New Zealand's North Island. Vanuatu is located to the west, and New Caledonia is located to the southwest. Tonga is located east of Fiji. Tonga is an archipelago comprised of 176 islands scattered over 270,000 square miles (700,000 square kilometers).

Wilma is forecast to continue moving southwest parallel to Fiji and New Caledonia as it makes its way toward New Zealand. On January 28 it is forecast to change course and head southeast bringing rains and gusty winds to northern New Zealand.

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...
