NASA's Aqua Satellite sees Khanun's remnants dissipating over China

23.07.2012
NASA's Aqua satellite has been tracking the remnants of Tropical Depression Khanun, and infrared data revealed that it has moved over northeastern China where it is now dissipating.

NASA's Aqua satellite passed over Khanun on July 18, 19 and 20 and tracked the northeastern progression of the tropical cyclone after it made landfall. On Wednesday, July 18 at 1659 UTC (12:59 p.m. EDT/U.S.), Tropical Depression Khanun's center was still in the Yellow Sea (west of South Korea).

At that time, the Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite saw a band of thunderstorms with cloud top temperatures colder than 220 kelvin (-63.6 F/-53.1C) over western South Korea, bringing heavy rainfall. A larger area of thunderstorms with cloud top temperatures as cold as -63F/-53C were over western North Korea at that time, dropping moderate rainfall.

Tropical Depression Khanun came ashore in western South Korea, bringing heavy rainfall with it on Thursday, July 19 as it moved in a north-northeasterly direction toward North Korea and northeastern China. On July 19 at 0405 UTC (12:05 a.m. EDT/U.S.), the heaviest rainfall and strongest thunderstorms appeared to be over the Kangnam Mountains in northern North Korea that also border eastern China. The Kangnam Mountains lie west of the Rangrim Mountains.

Although the center of Khanun's remnants moved into the Sea of Japan, it was bringing some scattered showers and thunderstorms to a few areas in northeastern China on July 20. NASA's Aqua satellite passed over the region on July 20 at 0447 UTC (12:47 a.m. EDT) and showed some scattered showers moving east into Khabarovsk Krai, Russia, a federal subject of Russia. Khunan's remnants are expected to dissipate today.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
