NASA caught Soulik's visible eye before making deadly landfall

16.07.2013
Typhoon Soulik still maintained an eye just before making landfall in southeastern China on July 13, and NASA's Terra satellite captured the eye in an image. Soulik's heavy rainfall in southern China is responsible for hundreds missing or dead.

On July 11, when Typhoon Soulik was approaching Taiwan, NASA and the Japanese Space Agency's Tropical Rainfall Measuring Mission satellite known as TRMM passed overhead in space.

TRMM's Precipitation Radar instrument captured data on rainfall rates, and that data was used to create a 3-D view of the typhoon looking from the northwest. That 3-D view clearly showed Typhoon Soulik's eye when it was east of Taiwan. The 3-D image also revealed the ring of thunderstorms surrounding the eye had rainfall rates of 2 inches/50 mm per hour.

Two days later on July 13, Typhoon Soulik was a category one typhoon when NASA's Terra satellite flew over the storm. Terra's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured another image of its eye. On July 13 at 0900 UTC (5 a.m. EDT), Soulik's maximum sustained winds were near 70 knots (80.5/129.6 kph). Those typhoon-strength winds extended 45 nautical miles (51.7 miles/83.3 km) from the center. At that time, Soulik's center had passed Taiwan and was 87 nautical miles (100 miles/161 km) west-northwest of Taipei, Taiwan, near 26.8 north and 120.1 east.

By 1500 UTC (11 a.m. EDT) on July 13, Soulik had made landfall near Fuzhou in southeastern China and was centered near 26.8 north and 119.1 east. After interacting with land, Soulik's maximum sustained winds fell to 60 knots (69 mph/111 kph).

According to the South China Morning Post, Soulik's flooding and landslides have left at least 300 people missing or dead. The southwestern province of Sichuan reported 68 deaths and 179 people missing. Two people died in the Guangdong province, and other parts of China reported 41 deaths and two missing.

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...
