Infrared NASA imagery reveals a weaker tropical cyclone in the South China Sea

22.06.2011
Tropical Depression 06W is still slowing, making its way through the South China Sea today and has weakened overnight. NASA infrared satellite imagery showed a much more disorganized storm with scattered convection, which accounts for its weakened status from tropical storm to tropical depression.

On June 21 at 1500 UTC (11 a.m. EDT) the newly weakened Tropical Depression 06W was located about 480 nautical miles east-southeast of Hanoi, Vietnam near 18.8 North and 113.8 East. Depression 06W's maximum sustained winds had decreased to 25 knots (28 mph/46 kmh). It was moving west-southwest at 9 knots (10 mph/17 kmh) and kicking up 11 foot-high waves in the South China Sea.


NASA's AIRS instrument on the Aqua satellite captured this infrared image of 06W on June 20 at 18:05 UTC (2:05 p.m. EDT) when it was still a tropical storm.

NASA's Atmospheric Infrared Sounder (AIRS) instrument that flies on the Aqua satellite captured an infrared image of 06W on June 20 at 18:05 UTC (2:05 p.m. EDT) when it was still a tropical storm. Since then, convection has become more scattered and winds have lessened. In addition, the low level center of the storm's circulation has become elongated due to wind shear. Elongation of a tropical cyclone is a sign of weakening.

Because of that wind shear, 06W is expected to barely maintain tropical depression strength before it makes landfall on Thursday, June 23 near Jhan Jiang, China.

The AIRS infrared image captures cloud top temperatures and the coldest temperatures appeared south of the center of circulation. Those cold cloud top temperatures represented the strongest thunderstorms in the tropical storm where rainfall rates could reach up to 2 inches / 50 mm per hour.

Because Tropical Depression 06W has begun moving to the west-southwest, the Joint Typhoon Warning Center has changed the forecast track and taken the depression farther south. The current landfall takes 06W just north of Hainan Island, China and then onto the mainland at the southwestern end of Guangdong province of Southern China.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
