NASA gets an icy cold wink from Hurricane Jova's eye

12.10.2011
Several NASA satellites have been following Hurricane Jova since birth and over the last day, Jova's eye has "winked" at them.

Satellite imagery from NASA's Aqua and Terra satellites have shown that Jova's eye was only sometimes visible and other times appeared cloud covered, making it appear as Jova "winking." Other satellites, such as NOAA's GOES-11 satellite captured Jova's "winks."


The visible image of Hurricane Jova on the left was taken from the MODIS instrument on NASA's Terra satellite on Oct. 10 at 1:40 p.m. EDT. Jova's extreme northeastern clouds are already over western Mexico, and the eye is clearly visible. On the right, a visible image from the GOES-11 satellite on Oct. 11 at 12:45 p.m. EDT shows Jova's eye "closed." Credit: Credit: NASA Goddard/MODIS Rapid Response Team/ NASA-NOAA GOES Project

In a visible image of Hurricane Jova from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite on Oct. 10 at 1:40 p.m. EDT, the eye was clearly visible. A visible image from NOAA's GOES-11 satellite on Oct. 11 at 12:45 p.m. EDT showed Jova's eye "closed" (or cloud-filled). The NASA GOES Project and the MODIS Rapid Response Teams are both located at NASA's Goddard Space Flight Center, and processed those images.

In addition to Jova's wink, the infrared AIRS instrument on NASA's Aqua satellite got a cold stare from Jova's eye. Infrared data measures cloud top temperatures, and NASA AIRS instrument noticed they were as cold as -80 Celsius (-112 Fahrenheit) in the thunderstorms in Jova's eyewall. Those frigid cloud top temperatures indicate there's a tremendous amount of power in the storm. The colder the cloud tops, the higher and stronger they are- and Jova is very powerful.

Today, dangerous Hurricane Jova continues to slowly approach the southwestern coast of Mexico today. At 11 a.m. EDT today, Oct. 11, it was near 17.8 North and 105.6 West. That's about 120 miles (190 km) southwest of Manzanillo, Mexico, and 180 miles (290 km) south of Cabo Corrientes. Jova's maximum sustained winds were near 115 mph (185 kmh). Jova is moving to the north-northeast at 5 mph (7 kmh). The National Hurricane Center expects Jova to speed up a little and turn to the north tonight. That means that the eye of the hurricane will approach the Mexican coast today and make landfall this evening.

Warnings continue to be in effect for Mexico as Jova slowly nears. A Hurricane warning is in effect from Punta San Telmo to Cabo Corrientes. A Tropical Storm Warning is in effect from Lazaro Cardenas to Punta San Telmo and Cabo Corrientes to El Roblito. Residents in the warning areas can expect significant flooding from storm surge and rough seas. Rainfall is forecast between 6 and 12 inches, with isolated totals to 20 inches. Residents should check local forecasts and prepare for this powerful hurricane.

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:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

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,...
