NASA Infrared Data Compares Super Typhoon Jelawat with Tropical Storm Ewiniar

NASA's Aqua satellite has been obtaining infrared, visible and other data everytime it passes over Typhoon Jelawat and Tropical Storm Ewiniar in the western North Pacific, and a combination of two images from Aqua's AIRS satellite puts the storms in perspective.

A combined image created from infrared data obtained by the Atmospheric Infrared Sounder (AIRS) instrument that flies on NASA's Aqua satellite provides a comparison of the two monster storms in the western North Pacific Ocean basin.

This combined image was created from infrared AIRS data of Super Typhoon Jelawat on Sept. 25 and Tropical Storm Ewiniar on Sept. 24 to give perspective of their distance from each other.

An infrared image of Typhoon Jelawat captured on Sept. 25 was combined with an image of Tropical Storm Ewiniar, that was taken on Sept. 24. The combined image gives perspective of the distance of the tropical cyclones from each other. The image showed the close proximity of the storms. Earlier in the week, Jelawat's outflow was affecting Ewiniar and preventing it from strengthening more quickly.

The data also showed a visible eye in the center of super typhoon Jelawat in the middle of powerful thunderstorms with very cold cloud top temperatures that exceed -63 Fahrenheit (-52 Celsius). Jelawat also has a rounded shape indicating that circulation is strong and symmetrical. Tropical Storm Ewiniar, however, appears somewhat asymmetrical, in the form of an elongated comma shape. The comma's "tail" is a large band of strong thunderstorms wrapping into Ewiniar's center from the southeast.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured a natural-color image on September 24, 2012, showing Jelawat just east of the Philippines. Sporting a distinct eye and spiral arms characteristic of strong storms, Jelawat spanned hundreds of kilometers (miles). As of September 24, 2012, the Joint Typhoon Warning Center (JTWC) classified Jelawat as a super typhoon. For the MODIS image, visit:

Jelawat remains a super typhoon today, Sept. 25, with maximum sustained winds near 140 knots (161 mph/259 kmh). It is located 385 nautical miles east-northeast of Manila, Philippines, and is moving north-northwestward at 6 knots (7 mph/11 kmh). Satellite imagery is showing tightly wrapped bands of thunderstorms spiraling into the eye of the storm. The eye is about 17 nautical miles wide. High pressure in the upper atmosphere and low wind shear are helping the super typhoon maintain its intensity. The JTWC projected storm track showed the storm moving toward the north-northwest over the next several days, passing near the island of Taiwan before turning toward the northeast.

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...
