An eye-opener: NASA sees Hurricane Raymond reborn for a brief time

29.10.2013
Tropical Storm Raymond moved away from western Mexico and into warmer waters with less wind shear over the weekend of Oct. 26-27, where it strengthened into a hurricane again. NASA's Aqua satellite captured an eye-opening image of Raymond before it ran into strong wind shear.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Hurricane Raymond that showed its eye had re-developed and opened after it re-strengthened in the Eastern Pacific. The image was taken on Oct. 27 at 21:15 UTC/5:15 p.m. EDT.

By Oct. 28, wind shear had again kicked up again and Raymond was weakening. Wind shear increased from the southwest pushing the strongest convection, and showers and thunderstorms northeast of the center.

An infrared, false-colored image of Hurricane Raymond was taken by the Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite on Oct. 28 at 9:23 UTC/5:23 a.m. EDT. The AIRS infrared image showed that the strongest storms had been displaced to the northeast of the center as a result of southwesterly wind shear. Those strong storms were still showing cold cloud top temperatures in excess of -63F/-52C indicating they were high in the troposphere and had the potential to generate heavy rain.

At 11 a.m. EDT/1500 UTC, Hurricane Raymond's maximum sustained winds were near 85 mph/140 kph and weakening. The center of Hurricane Raymond was near latitude 16.4 north and longitude 117.0 west, about 645 miles/1,035 km southwest of the southern tip of Mexico's Baja California. Raymond was moving toward the north near 7 mph/11 kph and is expected to turn toward the north-northeast. Raymond is forecast to weaken to a tropical storm late on Oct. 28 and a depression later that day.

The National Hurricane Center noted on Oct. 28 that Raymond is moving into an area with stronger wind shear, cooler sea surface temperatures and drier air: three factors that will lead to its dissipation in the next couple of days.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
