NASA catches Tropical Cyclone Amara's stretched out eye

19.12.2013
Tropical Cyclone Amara's eye appeared elongated on satellite imagery from NASA on December 18.

Tropical Cyclone Amara is spinning in the Southern Indian Ocean along with Tropical Cyclone Bruce, and both share elongated shapes. Even Amara's 10 nautical-mile-wide eye appeared stretched out.


NASA's Aqua satellite captured this image of Tropical Cyclone Amara in the South Indian Ocean on Dec. 18 at 09:05 UTC/4:05 a.m. EST and showed powerful thunderstorms (purple) around the storm's eye.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument took a visible picture of the storm on December 18 at 09:05 UTC/4:05 a.m. EST that showed that the eye was also cloud-filled. The MODIS image also showed bands of thunderstorms were wrapping into the center of circulation from the northeast and southwest.

At 0900 UTC/4 a.m. EST on December 18, Amara's maximum sustained winds had increased to 80 knots/92.0 mph/148.2 kph. Amara was centered near 16.0 south latitude and 70.5 east longitude, about 543 nautical miles/624.9 miles/1,006 km south of Diego Garcia. Amara has tracked to the west at 3 knots/3.4 mph/5.5 kph.

Amara is in an environment of low wind shear and warm sea surface temperatures that will allow it to continue to intensify, even rapidly. Amara is moving between two subtropical ridges (elongated areas) of high pressure. In three days Amara is forecast to encounter increasing wind shear which will weaken the system. High pressure is also expected to build south of Amara, which should slow it down and bring in cooler, drier air, which will also weaken the tropical cyclone.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
