NASA satellite sees strengthening in Tropical Cyclone Khanun

17.07.2012
When NASA's Aqua satellite passed over Tropical Depression Khanun on July 15, infrared data revealed some high, strong thunderstorms that hinted the cyclone would intensify. On July 16 Khanun had indeed become a tropical storm.

NASA's Aqua satellite flew over Khanun on July 15, 2012 at 1635 UTC (12:35 p.m. EDT) when it was a tropical depression. At that time the Atmospheric Infrared Sounder (AIRS) instrument onboard measured Khanun's cloud top temperatures.


NASA's Aqua satellite captured a look at Khanun's cloud top temperatures on July 15, 2012, at 1635 UTC (12:35 p.m. EDT) when it was a tropical depression. Coldest cloud top temperatures (purple) were as cold as or colder than -63 Fahrenheit (-52 Celsius), indicating strong thunderstorms. That was a clue to forecasters that Khanun would become a tropical storm, which it did the next day. Credit: Credit: NASA JPL, Ed Olsen

The storm's coldest cloud top temperatures were as cold as or colder than -63 Fahrenheit (-52 Celsius), indicating strong thunderstorms with the potential for heavy rainfall. AIRS data also revealed that the area of strongest thunderstorms were becoming more organized, indicating that the tropical depression could strengthen into a tropical storm.

On July 16 at 1500 UTC (11 a.m. EDT), Khanun had become a tropical storm when maximum sustained winds reached 35 knots (40 mph/64.8 kmh). At that time Khanun was centered about 370 nautical miles (425.8 miles/685.2 km) east of Kadena Air Base, Okinawa, Japan, near 25.4 North and 133.6 East. Khanun is moving to the west-northwest near 17 knots (19.5 mph/31.4 kmh).

Infrared data on July 16 showed the Khanun continued to consolidate and had a larger area of stronger central convection (rising air that forms the thunderstorms that make up the tropical cyclone), so the system is getting more organized and stronger. Khanun is currently in an area where wind shear is weak allowing for more strengthening.

The Joint Typhoon Warning Center expects Khanun to begin curving to the northwest and passing north of Kadena Air Base on its way to a landfall in South Korea later this week. Khanun is following the periphery of a north-south oriented sub-tropical ridge (elongated area) of high pressure building up south of Honshu. Khanun is expected to make landfall as a tropical storm in South Korea in a few days.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
