NASA's Infrared Satellite Imagery Shows Wind Shear Affecting Cyclone Ian

Tropical Cyclone Ian has been battered by wind shear and infrared imagery from NASA's Aqua satellite revealed that the bulk of the precipitation has been pushed east and southeast of the storm's center.

On January 13 at 0900 UTC/4 a.m. EST, Tropical Cyclone Ian's maximum sustained winds were near 65 knots/74.8 mph/120.4 kph, just at hurricane-strength. Just a day before, Ian's maximum sustained winds were near 80 knots/148.2 kph/92.0 mph.

NASA's Aqua satellite passed over Ian on January 13 at 01:23 UTC and saw strongest storms with the coldest cloud tops had temperatures (purple) east and southeast of the center.

Ian is moving to the southeast at 14 knots/25.9 kph/16.1 mph and is expected to continue in that direction. Ian was located about 882 nautical miles/1,633 km/1,015 miles south of Pago Pago, near 29.5 south and 169.9 west.

Ian has become significantly elongated as it has been battling strong wind shear. The precipitation has also been sheared to the east.

When NASA's Aqua satellite passed over Ian on January 13 at 01:23 UTC/January 12 at 8:23 p.m. EST, the Atmospheric Infrared Sounder or AIRS instrument captured an infrared picture of the storm. Infrared data showed the temperature of the storm's clouds and the sea surface temperatures surrounding it. The strongest storms with the coldest cloud tops had temperatures as cold as -63F/-52C and the AIRS image showed those storms were clearly pushed east and southeast of the center. The AIRS data also showed warmer, lower cloud top temperatures north and west of Ian's center.

AIRS data showed sea surface temperatures north of Ian were as warm as 300K/26.5C/80.3F/ while those south of Ian (and in the general direction the storm was heading) were near 290K/16.8C/62.3F or cooler.

Over the next couple of days, Ian is expected to become extra-tropical and a cold core low pressure area in the next day and a half.

Ian is no threat to land as it continues on its southeastern track.

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...
