NASA sees Tropical Storm Haima poised for Vietnam landfall

27.06.2011
NASA satellite imagery revealed that Haima has regained minimal tropical storm status with some powerful thunderstorms south of its center. Haima is moving west through the Gulf of Tonkin in the South China Sea between Hainan Island and Vietnam and is expected to bring heavy rains to Vietnam this weekend.

On June 24. 2011 at 0600 UTC (2 a.m. EDT), Tropical Storm Haima's winds were back up to 35 knots (40 mph/65 kmh) making it a minimal tropical storm. Haima is headed west-southwest at 10 knots (11 mph/19 kmh). Its center was near 20.3 North and 107.0 East about 90 nautical miles east-southeast of Hanoi, Vietnam.

Hanoi, Vietnam is north of where Haima is expected to make landfall and has been experiencing light rains from the western-most fringe of the tropical storm. On June 24 at 9 a.m. EDT, Hanoi had mostly cloudy skies and light rain with winds from the north at 16 mph. The temperature was 80 Fahrenheit (27 Celsius) and the minimum central pressure was 993 millibars (and dropping).

NASA's Aqua satellite passed over Haima on June 23 at 06:23 UTC (2:23 a.m. EDT) when its center was near Hainan Island, China. At that time, most of its heaviest thunderstorms were over the waters of the South China Sea, dropping rain at 2 inches/50 mm per hour. The Atmospheric Infrared Sounder (AIRS) instrument data showed a small area of strong convection and thunderstorms mostly south of the center of circulation.

Because infrared imagery shows temperature, it revealed that those thunderstorms had cold cloud top temperatures as cold as or colder than -63 Fahrenheit (-52 Celsius). On June 24, a microwave satellite image confirmed that the strongest convection and thunderstorms remained over the south of the center.

The warm waters of the Gulf of Tonkin have helped to reinvigorate Haima. Warm waters over 80F (26.5C) provide energy for a tropical cyclone. The waters in the Gulf of Tonkin are near 89.5F (32C).

The other factor that is critical in the strength of a tropical cyclone is wind shear. Strong wind shear can batter a storm and tear it apart. Current wind shear in the vicinity of Haima is between 15 and 20 knots (17-23 mph/27-37 kmh) and is expected to remain at that level through Haima's landfall in Vietnam tomorrow. That wind shear will help keep Haima from strengthening into a cyclone, although the Joint Typhoon Warning Center noted that it is expected to make landfall as a marginal tropical storm before dissipating over land.

Im Focus: Molecules Brilliantly Illuminated

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...

Im Focus: Spider silk key to new bone-fixing composite

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.

Im Focus: Writing and deleting magnets with lasers

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...

Im Focus: Gamma-ray flashes from plasma filaments

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...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
