On Sunday, Jan. 6, Tropical Storm Sonamu's maximum sustained winds were near 40 knots (46 mph/74 kph). Sonamu's center was located about 255 nautical miles (258.9 miles/416.7 km) southeast of Ho Chi Minh City, Vietnam, near 7.2 north and 108.9 east and continued to move west. At that time, the ragged low level center became exposed to outer winds. Satellite data showed that the strongest convection and heaviest rainfall was now pushed to the north because of wind shear.
NASA's Aqua satellite passed over Sonamu on Jan. 7, 2013, and noticed that the eastern half of the storm was almost devoid of clouds and showers, which is an effect of the dry air intrusion. The bulk of the cloud cover was west of the center.
On Monday, Jan. 7, Sonamu was curving to the southwest and is now expected to miss the Malay Peninsula. The Malay Peninsula contains the southernmost tip of Myanmar, Peninsular Malaysia, Singapore, and Southern Thailand. Sonamu is now expected to continue slowly on a southerly track.
Sonamu's maximum sustained winds are down to 30 knots (34.5 mph/55.5. kph). At 1500 UTC (10 a.m. EST/U.S.), Sonamu was located near 6.1 north latitude and 108.3 east longitude, about 290 nautical miles (333.7 miles/537.1 km) south-southeast of Ho Chi Minh City, Vietnam. Sonamu is crawling to the southwest at 1 knot (1 mph/1.8 kph). Sonamu is battling moderate wind shear, which is weakening the storm.
NASA's Aqua satellite passed over Sonamu on Jan. 7 and noticed that the eastern half of the storm was almost devoid of clouds and showers, which is an effect of the dry air intrusion. The Moderate Resolution Imaging Spectroradiometer captured an infrared image of the storm that showed the bulk of the cloud cover was west of the center.
According to the Joint Typhoon Warning Center on Jan. 7, infrared imagery shows a rapidly deteriorating, partially exposed low level circulation center with flaring convection along the western edge of the storm. Water vapor imagery indicated a pocket of dry air is wrapping along the eastern half of the low-level center toward Sonamu's center. Dry air saps convection, which forms the thunderstorms that make up a tropical cyclone.
Forecasters at the Joint Typhoon Warning Center expect that the combination of wind shear and dry air will lead to the dissipation of Sonamu over the next couple of days in the South China Sea.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
