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: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
