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: AI monitoring of laser welding processes - X-ray vision and eavesdropping ensure quality

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.

Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...

Im Focus: A structural light switch for magnetism

A research team from the Max Planck Institute for the Structure of Dynamics (MPSD) and the University of Oxford has managed to drive a prototypical antiferromagnet into a new magnetic state using terahertz frequency light. Their groundbreaking method produced an effect orders of magnitude larger than previously achieved, and on ultrafast time scales. The team’s work has just been published in Nature Physics.

Magnetic materials have been a mainstay in computing technology due to their ability to permanently store information in their magnetic state. Current...
