NASA sees a 14-mile-wide eye and powerful Super Typhoon Songda

30.05.2011
Typhoon Songda became a Super Typhoon in the evening on May 26, 2011 (Eastern Daylight Time) was it reached a Category 5 status on the Saffir-Simpson Scale. NASA satellite data shows that the monster storm with a 14 mile-wide eye has weakened due to adverse wind conditions today and is still a powerful Category 4 typhoon.

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured an infrared image of Super Typhoon Songda on May 27, 2011 at 5:05 UTC (1:05 a.m. EDT). At that time Songda was a Category 4 storm. The infrared image showed a large area of very strong thunderstorms with heavy rainfall surrounding the eye of the storm. The eye is almost 14 miles (12 nm/22 km) in diameter and those thunderstorms were dropping rainfall as much as 2 inches (50 mm) per hour.


This infrared image of Super Typhoon Songda was captured by the AIRS instrument on NASA's Aqua satellite on May 27, 2011, at 5:05 UTC (1:05 a.m. EDT). At this time, Songda was a Category 4 storm. The purple areas indicate very strong thunderstorms with heavy rainfall and there is a large area of them that surround the visible eye. Taiwan is northwest of the storm. Credit: NASA/JPL, Ed Olsen

On May 27 at 1500 UTC (11 a.m. EDT), Typhoon Songda's maximum sustained winds were near 125 knots (143 mph/231 kmh) down from its peak of 140 knots (161 mph/260 kmh) which it reached late on May 26. Songda has tracked north-northwest but is expected to turn to the north-northeast.

AIRS infrared imagery from today shows that the cloud tops are warming, and convection (rapidly rising air that forms the thunderstorms that power a tropical cyclone) is weakening. The rule with infrared imagery and thunderstorms is: the colder the cloud top, the stronger the convection and stronger the thunderstorm. So, what's making Songda weaken? Cooler sea surface temperatures (now that its north of 20 degrees north latitude) and increasing southwesterly vertical wind shear.

Taiwan is already feeling the effects from Songda as the surf has kicked up and is expected to remain rough until Songda passes this weekend. Songda is currently expected to pass just to the east of Ishigakijima island and to the west of Kadena Air Base, putting the island on the strongest side (the northeastern corner) of the storm. Songda is then forecast by the Joint Typhoon Warning Center to continue moving northeast and curving past the east coast of Japan, while its center remains at sea. By May 30, Songda is expected to have passed Japan.

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
