NASA satellite sees a more powerful Hurricane Rina, warnings up in Mexico

26.10.2011
Hurricane warnings are in effect in Mexico's Yucatan Peninsula and visible and infrared satellite imagery from NASA continues to show Hurricane Rina getting stronger. Rina is now a category 2 hurricane on the Saffir-Simpson hurricane scale.

The Mexican government issued a hurricane warning for the east coast of the Yucatan Peninsula from north of Punta Gruesa to Cancun. From Chetumal to Punta Gruesa a tropical storm warning is in effect.


This visible image of Hurricane Rina was taken by the MODIS instrument on NASA's Terra satellite on Oct. 24, 2011, at 12:15 p.m. EDT (16:15 UTC) when it was off the coast of Mexico.

As NASA's Terra satellite passed over Hurricane Rina on October 24 at 12:15 p.m. EDT (16:15 UTC) the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument took a visible image of the storm as it nears the Yucatan. The strongest thunderstorms around the center are casting shadows on the surrounding lower clouds. Rina's southwestern edge was over Honduras at this time.

On October 25, when NASA's Aqua satellite passed overhead it collected valuable data about Rina's cloud top temperatures. High, cold cloud top temperatures indicate a lot of power in the storm, as strong uplift pushes cloud tops higher in the troposphere, where temperatures drop. The higher and colder the thunderstorms within a hurricane, the stronger they are, and the heavier the rainfall within.

When Aqua passed overhead, the infrared data was collected from the Atmospheric Infrared Sounder (AIRS) instrument on the satellite. It showed a large area of strong thunderstorms completely surrounding the center of circulation.

Infrared imagery is color coded at NASA. It is created at the NASA Jet Propulsion Laboratory in Pasadena, Calif. In the image from earlier today, the strongest, coldest, highest cloud tops that surrounded the center of Rina (the eye) were colder than -63 Fahrenheit (-52 Celsius). The eye showed warmer temperatures, indicating that it may be seen on visible satellite data.

On October 25 at 11 a.m. EDT, Rina continues to strengthen, as is evident from the AIRS infrared imagery showing powerful convection surrounding the eye of the storm. Rina's maximum sustained winds are now up to 105 mph (165 kmh).

Hurricane Rina is closing in on Mexico's Yucatan Peninsula. It is now centered near 17.4 North and 83.9 West, about 300 miles (480 km) east-southeast of Chetumal, Mexico and 305 miles (490 km) southeast of Tulum, Mexico. That's not too far away when you consider that the tropical storm-force winds extend out 115 miles (185 km) from the center. The hurricane-force winds, however are confined to a much smaller area at this time- outward 15 miles (30 km) from the center.

The National Hurricane Center (NHC) noted that Rina is crawling to the west-northwest near 3 mph (6 kmh) and is expected to turn to the northwest and speed up a little over the next two days. Rina's center is expected to approach the Mexican coastline in the hurricane warning area by Wednesday night or early Thursday. Tropical storm-force winds are expected in the warning area tomorrow (Oct. 26) afternoon, followed by hurricane-strength winds.

Heavy rainfall as seen in NASA AIRS infrared imagery is going to accompany those winds. The NHC is expecting Rina to produce between 8 and 16 inches of rainfall over the eastern Yucatan late Wednesday and early Thursday, as dangerous storm surge hits coastal areas. Storm surge is expected to be as much as 5 to 7 feet above normal tide levels near the track of the storm's center and right of center.

NASA AIRS infrared data also shows that Rina is in an area of very warm ocean temperatures, over the 80 degree Fahrenheit (26.6 C) minimum to maintain a tropical cyclone, which will help Rina strengthen over the next day or two.

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,...
