NASA sees pinhole eye seen in weakening Tropical Cyclone Winston

24.02.2016

NASA-NOAA's Suomi NPP satellite saw that Tropical Cyclone Winston maintained a pinhole eye as it tracked east of southern Vanuatu's islands in the Southern Pacific Ocean on Feb. 23, 2016. Infrared imagery showed bands of strong thunderstorms were wrapping into the low-level center of the storm.

On Feb. 23, 2016 at 0140 UTC (Feb. 22, 2016 at 8:40 p.m. EST) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Cyclone Winston that showed a pinhole eye as it was moving east of Vanuatu's southernmost islands.


On Feb. 23, 2016 at 01:53 UTC (Feb. 22 at 8:53 p.m. EST), the AIRS instrument aboard NASA's Aqua satellite saw some cloud top temperatures in Tropical Cyclone Winston were colder than -63F/-53C (purple), indicating they were high into the troposphere.

Animated enhanced infrared satellite imagery indicated a slowly-decaying low-level circulation center with curved strong bands of thunderstorms wrapping into the center of the storm.

The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite provided infrared temperature data on the system on Feb. 23, 2016 at 01:53 UTC (Feb. 22, 2016 at 8:53 p.m. EST).

Some cloud top temperatures were colder than minus 63 Fahrenheit/ minus 53 Celsius, indicating they were high into the troposphere. Cloud top temperatures that cold have shown that those storms can produce heavy rainfall

Joint Typhoon Warning Center (JTWC) said that at 1500 GMT (10 a.m. EST) Winston's maximum sustained winds dropped to 70 knots (80.5 mph/129.6 kph) making it a Category 1 hurricane.

It was located about 303 nautical miles (348 miles/561.2 km) west-southwest of Suva, Fiji near 20.7 degrees south latitude and 173.8 degrees east longitude. Winston had increased in forward speed since Feb. 22, 2016 and was moving to the south-southeast to 9 knots (10.3 mph/16.6 kph).

JTWC forecasters expect that Winston will turn southwestward to west-southwestward on Feb. 24, 2016 as it transitions to the steering influence of a building sub-tropical ridge (elongated area of high pressure) to the south. Tc 11p is expected to weaken significantly after Feb. 24, 2016 as it encounters strong vertical wind shear and cooler sea surface temperatures.

Im Focus: Artificial agent designs quantum experiments

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.

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

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...

Im Focus: Room-temperature multiferroic thin films and their properties

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.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
