Two views of Super Typhoon Atsani from NASA's Aqua Satellite

20.08.2015

NASA's Aqua satellite passed over Super Typhoon Atsani and captured visible and infrared data on the monster storm. The AIRS and MODIS instruments gathered data that revealed powerful thunderstorms surrounding a wide-open eye.

On August 18 at 03:37 UTC (11:37 p.m. EDT, Aug. 17) the AIRS instrument aboard NASA's Aqua satellite gathered infrared data on Atsani. In a false-colored image of the data created at NASA's Jet Propulsion Laboratory in Pasadena, California, cloud top temperatures revealed cloud top temperatures as cold as 210 kelvin/-63.1F/-81.6C surrounding the eye. Cloud top temperatures that cold indicate very high, powerful thunderstorms with the capability for generating heavy rainfall.


On Aug. 19 the AIRS instrument aboard NASA's Aqua satellite saw Super Typhoon Atsani's cloud top temperatures as cold as 210 kelvin/-63.1F/-81.6C (purple) in powerful thunderstorms circling the center.

AIRS data also showed that the sea surface temperatures around the storm were warmer than 300 kelvin (80.3 Fahrenheit/26.8 Celsius), warm enough to support the typhoon.

At the same time, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard Aqua captured a visible picture of the storm. The MODIS image showed bands of thunderstorms wrapping into the center from the northwestern and southeastern quadrants.

On August 19, 2015 at 1500 UTC (11 a.m. EDT) Super Typhoon Atsani had maximum sustained winds near 140 knots (161.1 mph/ 259.3 kph), making it a Category 5 hurricane on the Saffir-Simpson Scale. It was centered near 19.6 North latitude and 151.3 East longitude, about 637 nautical miles (733 miles/1,180 km) east-southeast of Iwo To island, Japan. Atsani was moving to the northwest at 7 knots (8 mph/12.9 kph).

Typhoon-force winds were occurring up to 30 nautical miles (34.5 miles/55.5 km) from the center, and tropical storm-force winds were occurring up to 180 nautical miles (207 miles/333 km) from the center, making the storm about 360 nautical miles (414 miles/666.7 km) wide!

Atsani is moving northwest and forecasters at the Joint Typhoon Warning Center expect it will intensify to 145 knots by August 20. Atsani is then expected to becoming extra-tropical as it turns northeast, remaining well south of Japan.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
