NASA satellite sees birth of Tropical Storm Ethel, now threatening Rodrigues

20.01.2012
NASA's Aqua satellite passed over Tropical Storm Ethel on January 19, 2012 after she was born in the Southern Indian Ocean. The island of Rodrigues is now under Tropical Cyclone Warnings as Ethel approaches and strengthens.

When Aqua passed over newborn Ethel at 09:30 UTC (4:30 a.m. EST) on Jan. 19, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard Aqua captured a visible image of the storm, and showed that it had good circulation. The strongest storms appear to be around the center and northwest of center. Bands of thunderstorms from the east-southeast appear to spiral into Ethel's center on the MODIS satellite imagery.

At 0300 UTC on January 19 (10 p.m. EST, Jan. 18) Tropical Storm Ethel had maximum sustained winds near 35 knots (40 mph/65 kmh). Ethel was 810 miles east-northeast of La Reunion Island, centered near 14.2 South longitude and 67.7 East latitude. Ethel was moving to the west-southwest at 11 knots (~13 mph/20 kmh).

Currently, Ethel threatens the island of Rodrigues. Rodrigues is the smallest of the Mascarene Islands and was home to 40,000 people in 2006. It is a dependency of Mauritius. According to Wikipedia, it is located 348 miles (560 km) east of Mauritius island. It is surrounded by a coral reef and about 43 square miles (109 km²).

The Mauritus Meteorological Service (MMS) has posted a tropical cyclone class two warning for Rodrigues. A class two warning means that within 12 hours, the warning area will likely experience hurricane-force wind gusts of 75 mph (120 kilometers) per hour. The MMS calls for downpours and gusty winds today, with rain becoming heavier and more frequent on January 20. Sustained winds are expected to be near 25 mph (40 kmh) with gusts as high as 56 mph (90 kmh) during the evening hours on Jan. 19, 2012. Seas are expected to be rough.

Because Ethel is in an area with warm sea surface temperatures (warmer than the 80F/26.6C threshold needed to maintain a tropical cyclone) and low wind shear, she is expected to strengthen quickly into hurricane (cyclone) strength. Afterward, Ethel is expected to encounter increased wind shear conditions which will again weaken the storm.

The cyclone is forecast to intensify rapidly to hurricane strength before adverse atmospheric conditions prompt a weakening trend.

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...
