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: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
