NASA Satellite Sees Tropical Storm Cyril a Strong, Compact Storm

Tropical Storm Cyril was known as "11P" has been strengthening since February 6, and still appears very compact on infrared NASA satellite data.

In the morning hours of February 7 (local time Vanuatu) Cyril was located south of the island of Vavau in the Kingdom of Tonga. All warnings for Niue and Tonga have now been cancelled.

During the morning hours of February 7, Cyril picked up speed and is moving to the southeast at 28 knots (~32 mph/~52 kph). Cyril's maximum sustained winds were near 45 knots (~52 mph/~83 kph). Those tropical-storm-force winds only extended out to 35 miles (~56 km), making the storm over 70 miles (~113 km) in diameter. Satellite imagery from February 6 helped forecasters estimate that the clouds associated with Cyril extended to 120 miles in diameter.

By 1500 UTC on February 7 (10 a.m. EST or 4 a.m. on Feb. 8 Pacific/Tongatapu local time) Cyril was centered about 545 nautical miles (627 miles/1,009 km) south of Pago Pago, American Samoa near 23.8 South and 165.0 West. Cyril covered 175 nautical miles (~196 miles/~315 km) in 12 hours during the morning hours of February 7.

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured an infrared image of Cyril's clouds on February 7, 2012 at 12:29 UTC. Cyril still appears as a very compact, rounded storm. The strongest thunderstorms remained close to the center of circulation where cloud top temperatures are below -63 F (-52.7C).

The Australian Broadcasting Corporation noted that the Vavau airport reported sustained winds of 45 knots (~52 mph/~83 kph) on Feb. 8 at 6:30 a.m. local Pacific/Tongatapu time.

As Cyril continues to speed to the southeast, the vertical wind shear is forecast to increase and sea surface temperatures are expected to be much cooler. In fact, water temperatures will decrease to 25 degrees Celsius (77F) and colder. Sea surface temperatures must be at least 26.6C (80F) to support a tropical cyclone, otherwise the system begins to weaken. The Joint Typhoon Warning Center gives Cyril two days before it dissipates.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
