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.
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 (purple) were over the waters of the South China Sea, dropping rain at 2 inches/50 mm per hour. Credit: NASA/JPL, Ed Olsen
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.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
