NASA satellite measures monstrous Hurricane Igor as a '10-hour drive'

16.09.2010
Hurricane Igor is a monster hurricane in terms of strength and size. To get a perspective on its size, it is the same distance from one end of the storm to the other as it is from Boston, Mass. to Richmond, Va., some 550 miles. That's a 10-hour drive from one end to the other, and NASA satellites captured that entire distance in one image.

Because Hurricane Igor is a large storm and even if Igor doesn't make a direct landfall in Bermuda, the extent of the winds (the wind field) is so large that the National Hurricane Center noted that Bermuda can be buffeted by winds of hurricane-force or tropical storm-force on its current track.


This image of Hurricane Igor was captured from the Moderate Resolution Imaging Spectroradiometer (MODIS) Instrument that flies aboard NASA\'s Terra satellite at 1420 UTC (10:20 a.m. EDT) on Sept. 14. The storm is 550 miles and would take 10 hours to \"drive across.\"

Maximum sustained winds this morning were near 145 mph, and although the hurricane-force winds extend outward from the center up to 45 miles (90 miles in diameter), tropical-storm-force winds extend as far as 225 miles (550 miles in diameter). Igor is expected to be close to Bermuda within the next 3 to 4 days.

Hurricane Igor was captured in one image from the Moderate Resolution Imaging Spectroradiometer (MODIS) Instrument that flies aboard NASA's Terra satellite at 1420 UTC (10:20 a.m. EDT) on Sept. 14. The image showed the massive extent of Igor's cloud cover, stretching over 500 miles. The image also showed that Igor's eye was covered with high clouds.

At 5 a.m. EDT on Sept. 15, infrared imagery from NASA's Atmospheric Infrared Sounder (AIRS) instrument indicated that the cloud tops had warmed over the western part of the center, and that Igor's eye had cooled. That indicates slight weakening, because higher, colder cloud tops indicate strong convection (rapidly rising air that forms the thunderstorms that power Igor) and when they warm that means that convection has waned. Infrared imagery from AIRS on Sept. 14 at 1723 UTC (1:23 p.m. EDT) continued to show strong convective activity in his center as indicated by high thunderstorms that were as cold as -63F. Since that time, cloud tops have warmed.

At 0352 UTC this morning (11:52 p.m. EDT Sept. 14) NASA's Tropical Rainfall Measuring Mission satellite showed that the southwestern part of the eyewall has eroded, further confirming the weakening that the infrared data showed. However, the National Hurricane Center noted that Igor is still in a good environment for strengthening.

On Sept. 15 at 5 a.m. EDT, Hurricane Igor was still a powerful Category 4 hurricane on the Saffir-Simpson scale with maximum sustained winds of 145 mph. It was about 1,090 miles southeast of Bermuda, near 19.5 North and 54.5 West. Igor was moving west-northwest near 10 mph and had a minimum central pressure of 935 millibars.

Igor is expected to run into southerly wind shear in 3 to 4 days, which may cause some weakening. NASA satellites will watch for those signs as Igor continues moving through the Atlantic Ocean this week.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
