Satellite imagery shows Typhoon Vamco has a huge 45-mile wide eye

26.08.2009
Vamco was in the process of becoming an extra-tropical storm on August 25, but his sustained winds were still around 74 mph, making him a category one typhoon. NASA's QuikScat satellite confirmed his powerful winds and NASA's Terra satellite visible imagery still revealed a strong storm.

At 2 a.m. EDT on August 25, Vamco was still enroute to the Alaskan islands headed north-northeast at 38 mph in the north Central Pacific Ocean. He was about 980 miles west-southwest of Kiska, Alaska. That's near 41.6 north and 158.9 east. Vamco will continue moving northeast toward the far southwestern Aleutian Islands.

NASA's QuikScat satellite was able to peer through Vamco's clouds on August 24 using microwave technology and actually measure the winds on the surface of the ocean beneath him. QuikScat found Vamco still had sustained winds near 65 knots (74 mph), so he was still at a category one hurricane strength at that time.

Meanwhile, in the early morning hours of August 25, visible satellite imagery from NASA's Terra satellite and the Moderate Imaging Spectroradiometer (MODIS) instrument revealed Vamco's clouds still had a good circulation.

Vamco is starting to weaken, however. Infrared satellite imagery, such as that from NASA's Aqua satellite's Atmospheric Infrared Sounder (AIRS) instrument, indicated that Vamco's eye has become elongated and grown larger. Also, Vamco's convection and rainfall has started to erode as wind shear has increased. Vamco is expected to continue weakening as winds continue to batter his circulation.

Although the U.S. Navy's Joint Typhoon Warning Center has issued their final advisory on Vamco, shipping interests in the North Pacific Ocean should be aware of high seas.

Im Focus: Quantum optical sensor for the first time tested in space – with a laser system from Berlin

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
