NASA's Aqua Satellite Sees Birth of Two Tropical Cyclones in Eastern Pacific

07.10.2011
The tropics in the eastern Pacific were quiet for a couple of days after Hurricane Hilary dissipated, and today gave birth to Tropical Depression 10 and Tropical Storm Irwin. NASA's Aqua satellite captured an infrared image of both storms and saw the powerful convection in the center of Irwin that enabled the storm to go from a depression to a tropical storm in a short time.

The eleventh tropical depression quickly grew into Tropical Storm Irwin this morning, as strong convection surged around its center of circulation. That convection (rising air that creates the thunderstorms that power a tropical cyclone) was seen in infrared imagery taken early this morning, Oct. 6, from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite. The cold cloud tops from those strong thunderstorms were colder than -63 Fahrenheit (-52 Celsius) and represented the strength in the core of Irwin.

At 11 a.m. today, Oct. 6, Tropical Storm Irwin's maximum sustained winds had grown to 40 mph, after forming as a depression just 5 hours before. Irwin was located about 855 miles (1,375 km) south-southwest of the southern tip of Baja California, Mexico near 12.4 North and 116.8 West. It was moving away from land to the west-northwest near 6 mph (9 kmh). The National Hurricane Center expects Irwin to turn to the north and then north-northeast tomorrow. Irwin is expected to strengthen slowly in the next 48 hours. Minimum central pressure was 1005 millibars.

Closer to land, NASA's Aqua satellite saw a smaller Tropical Depression 10E. Tropical Depression 10E (TD10E) appears pretty close to Tropical Storm Irwin on the AIRS infrared imagery. It is located to the east-southeast of Tropical Storm Irwin, and it appears to be a smaller, more compact, rounded area of strong convection. Specifically, TD10E is located near 10.3 North and 105.8 West, about 610 miles south of Manzanillo, Mexico. It has maximum sustained winds near 35 mph (55 kmh) and is moving to the west-northwest near 8 mph (13 kmh). The AIRS infrared data shows strong convection around the southwestern edge of the center of circulation, indicating that TD10E could also become a tropical storm shortly.

The National Hurricane Center noted that "The tropical cyclone is forecast to remain over warm waters and in a low (wind) shear environment during the next several days" and predicts it could become a hurricane in two or three days. By mid-day on Saturday, Oct. 8, the National Hurricane Center forecast projects TD10E to change course and "recurve ahead of a large trough (elongated area of low pressure) diving southeastward across the southwest United States and the Baja Peninsula."

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".

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...
