NASA satellite sees wind shear whipping Tropical Cyclone Gillian

26.03.2014

A visible image from NASA's Aqua satellite provides a clear picture that wind shear is responsible for weakening the once mighty Tropical Cyclone Gillian from hurricane to tropical storm strength.

When NASA's Aqua satellite flew over Gillian on March 25 at 06:30 UTC/2:30 a.m. EDT, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument took a visible picture of the storm.


NASA's Aqua satellite captured this image of Gillian on March 25 at 06:30 UTC/2:30 a.m. EDT, now a tropical storm in the Southern Indian Ocean. Wind shear has pushed clouds and showers away from the center.

That image showed that wind shear has pushed clouds and showers away from the center as the storm weakened to a tropical storm.

In the MODIS image, the center of Gillian's circulation is surrounded by some cloudiness, while the bulk of clouds and showers has been pushed to the east-southeast from wind shear from the northwest.

On March 26 at 0900 UTC/5 a.m. EDT, Gillian's maximum sustained winds were near 60 knots. It was centered near 19.6 south latitude and 103.9 east longitude, about 594 nautical miles/683.6 miles/1,100 km west-northwest of Learmonth, Western Australia.

Gillian was moving to the south at 6 knots/6.9 mph/11.1 kph.

The Joint Typhoon Warning Center or JTWC expects Gillian to weaken quickly today as it turns to the southwest in the open waters of the Southern Indian Ocean.

The factors contributing to its rapid weakening include strong wind shear, subsidence or sinking air aloft, and movement into cooler sea surface temperatures.

JTWC forecasters expect Gillian to dissipate by March 26.

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...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
