On Aug. 8 at 1853 UTC (2:53 p.m. EDT) NASA's Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite showed some cloud top temperatures in bands of thunderstorms and around the center of Tropical Depression 11W were as cold as -63F/-52C, indicating strong storms.
This infrared image from NASA's Aqua satellite on Aug. 8 showed some cloud top temperatures in bands of thunderstorms and around the center of Tropical Depression 11W are as cold as -63F/-52C (purple) indicating strong storms.
What does Infrared Data Show?
AIRS infrared images are false-colored to show temperature differences. Scientists look at cloud top temperatures to understand how high the thunderstorms are that make up a tropical cyclone - and there are hundreds of thunderstorms that make up one storm. The colder the cloud top temperature, the higher the top of the thunderstorm reaches into the troposphere and the stronger the storm. NASA research has indicated that cloud top temperatures that reach or exceed the threshold of -63F/-52C typically have heavy rainfall rates.
On Aug. 9 at 1200 UTC (8 a.m. EDT), Tropical Depression 11W's maximum sustained winds near 30 knots/34.5 mph/55.5 kph. 11W's center was located about 671 nautical miles/ 772.2 miles/1,243 km east of Manila, Philippines, near 14.0 north and 132.0 east. 11W is moving west at 10 knots/11.5 mph/18.5 kph. When 11W strengthens into a tropical storm, it will be renamed Tropical Storm Utor.
Forecasters at the Joint Typhoon Warning Center have forecast Tropical Depression 11W's path. After crossing Luzon on Aug. 11 as a tropical storm, 11W is expected to become a typhoon as it moves through the South China Sea on Aug. 12 and 13 before making a landfall in southern China.

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.
