NASA looks at rare Arabian Sea tropical cyclone in 3-D

10.06.2015

Tropical cyclones are not too common in the Arabian Sea, but tropical cyclone 01A, now renamed Ashobaa, formed this week. NASA/JAXA's Global Precipitation Measurement or GPM core satellite flew over Ashobaa and gathered data that provided a 3-D look at the rainfall in the storm.

The GPM core observatory satellite flew over Ashobaa on the morning of June 8 at 0811 UTC (4:11 a.m. EDT). Tropical cyclone Ashobaa had sustained wind speeds of about 40 knots (46 mph) when the satellite passed overhead.

On June 9 at 0900 UTC (5 a.m. EDT), tropical cyclone Ashobaa had maximum sustained winds near 50 knots (57.5 mph/92.6 kph). Ashobaa was centered near 20.7 north latitude and 64.1 east longitude, about 290 nautical miles (333.7 miles/ 537.1 km) south-southwest of Karachi, Pakistan. Ashobaa is moving west-northwest at 8 knots (9.2 mph/14.8 kph).

Satellite data on June 9 showed that the storm is tightly wrapped, although elongated as clouds and showers are being pushed to the west because of persistent moderate easterly wind shear.

The Joint Typhoon Warning Center (JTWC) predicts that tropical cyclone Ashobaa will become more powerful and have winds of 65 knots (about 75 mph) by June 10 as it moves through warm sea surface temperatures. Ashobaa is then predicted to weaken as dry stable air is expected to affect the system. It is forecast to turn west where it expected to make landfall on June 12 near Ras al Hadd, a village in the Ash Sharqiyah district in Oman.

As Ashobaa continues curving to the west in the Arabian Sea, it is generating rough surf along the coasts of Oman, southeastern Iran and Pakistan.

GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments measured rain falling at a rate of over 60 mm (2.3 inches) per hour in strong thunderstorms southwest of the storm's center of circulation.

At NASA's Goddard Space Flight Center in Greenbelt, Md., a 3-D view was constructed using data from DPR Ku band radar data. The 3-D view of GPM revealed Ashobaa had very powerful thunderstorms near the center of the newly formed storm reaching heights above 17 km (10.5 miles). These tall thunderstorms near the center of a tropical cyclone can be as sign that intensification will occur in the future.

Im Focus: How to induce magnetism in graphene

Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic properties that could permit future spintronic applications. The results have just been published in the renowned journal Nature Nanotechnology.

Depending on the shape and orientation of their edges, graphene nanostructures (also known as nanographenes) can have very different properties – for example,...

Im Focus: How do scars form? Fascia function as a repository of mobile scar tissue

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.
