NASA gets eyeballed from Cyclone Claudia

11.12.2012
NASA's Aqua satellite got "eyeballed" from Cyclone Claudia in the Southern Indian Ocean when two instruments captured the storm's eye in infrared and visible light. Satellite data indicates that Claudia's eye is about 10 nautical miles wide.

On Dec. 10 at 0841 UTC (3:41 a.m. EST), NASA's Aqua satellite's Atmospheric Infrared Sounder (AIRS) instrument captured an infrared view of Cyclone Claudia which showed a clear eye surrounded by powerful thunderstorms. The thunderstorms that surrounded the eye were high in the troposphere and cloud top temperatures topped -63 Fahrenheit (-52 Celsius).

During that same overpass the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument also aboard Aqua captured a stunning visible image of Claudia that clearly showed an eye.

Claudia became a cyclone over the weekend of Dec. 8 and 9. On Dec. 8, Tropical Cyclone Claudia's winds increased to cyclone strength. During the early morning hours on Dec. 8 NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed overhead and identified that the heaviest rainfall lay south of the eye of the storm. Rain in that quadrant of the storm was falling at a rate of 30 millimeters (1.2 inches) per hour.

On Sat. Dec. 8, Claudia's maximum sustained winds were near 100 knots (115 mph/185 kph). Claudia was a category 3 cyclone and considered a major storm. It was centered near 14.7 south latitude and 74.6 east longitude, or about 450 nautical miles south-southeast of Diego Garcia. Claudia was moving to the southwest at 4 knots (5 mph).

On Monday, Dec. 10, Cyclone Claudia's maximum sustained winds increased to 105 knots (121 mph/194.5 kph). Claudia had moved about 175 nautical miles in two days and was centered near 18.0 south latitude and 73.8 east longitude, about 625 nautical miles south of Diego Garcia. Claudia continues to move southward at 7 knots (8 mph/13 kph) over open ocean.

Claudia is moving southward along the western edge of ridge (elongated area) of high pressure, and is expected to speed up and turn toward the southeast according to the forecasters at the Joint Typhoon Warning Center.

Claudia may not be giving any NASA satellite the "eye" after another day or two when it runs into cool waters and an area of stronger vertical wind shear.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
