NASA sees first Atlantic hurricane fizzling in cool waters

25.06.2012
Chris may have been the Atlantic Ocean Hurricane Season's first hurricane, but didn't maintain that title for long. NASA satellite data revealed one good reason why Chris had weakened and became a post-tropical storm.

Sea surface temperatures play a big role in keeping a tropical cyclone alive. They need warm seas of at least 300 Kelvin (80 Fahrenheit/26.8 Celsius) to maintain strength. NASA's Aqua satellite revealed that those conditions were not met where Chris is located in the Atlantic Ocean.


NASA's Aqua satellite passed over Post-Tropical Storm Chris on June 22 at 12:47 a.m. EDT. The infrared data from the AIRS instrument onboard Aqua indicated the storm is in waters that are too cool to maintain its strength. The waters are near 290 Kelvin (62F/16.8C). Credit: NASA/JPL, Ed Olsen

When NASA's Aqua satellite passed over Chris at 0447 UTC (12:47 a.m. EDT) today, June 22, the Atmospheric Infrared Sounder (AIRS) instrument captured a new infrared image of Chris' clouds and surrounding sea surface temperatures. The sea surface temperatures to the south of Chris are at least 300 Kelvin (80 Fahrenheit/26.8 Celsius) and warmer. In the area where Chris is located, AIRS revealed that sea surface temperatures are closer to 290 Kelvin (62 Fahrenheit/16.8 Celsius).

At 11 a.m. EDT on June 22, Chris was now classified as a post-tropical storm with maximum sustained winds near 45 mph (75 kmh). Chris was far to the north near 44.6 North and 46.9 West, about 335 miles (535 km) east-southeast of Cape Race, Newfoundland, Canada. Chris was moving to the west-southwest near 16 mph (kmh), and is expected to slow and turn southward. Chris' minimum central pressure is 990 millibars.

According to the National Hurricane Center, Chris "should merge with another extratropical low on Saturday [June 23]" in the north Atlantic Ocean.

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...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

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...
