Stunning NASA infrared imagery of Hurricane Igor reveals a 170 degree temperature difference

15.09.2010
NASA satellites provide infrared images to forecasters that show temperature, and today's imagery of powerful Hurricane Igor showed the storm's perfect form and the warm ocean waters around it that are keeping it fueled. NASA's infrared data also revealed a huge difference of 170 degrees between the cold cloud tops in Hurricane Igor and the warm sea surface temperatures powering it below.

When NASA's Aqua satellite passed over Igor on Sept. 14 at 14:47 UTC (10:47 a.m. EDT) the Atmospheric Infrared Sounder (AIRS) instrument captured icy cold cloud top temperatures in the strong thunderstorms that surround Igor's well-defined eye. Those cloud top temperatures were as cold or colder than -90F, indicating they were near the top of the troposphere, and very strong.


This impressive infrared image of Hurricane Igor from NASA\'s AIRS instrument shows a clear and large eye, and very strong convection (purple) and high, powerful thunderstorm cloud tops around his center. The image was captured from the AIRS instrument on NASA\'s Aqua satellite on Sept. 14 at 14:47 UTC (10:47 a.m. EDT). Note the warm ocean temperatures (dark orange) well over the 80 degree F threshold needed to maintain intensity.

The infrared imagery also showed the warmer, open 20 nautical-mile wide eye (because it was not cloud-filled). In addition, AIRS got a reading on the sea surface temperatures around Igor, which were all warmer than the 80F threshold needed to maintain a tropical cyclone, so Igor has a good energy source for the next day or two. So, the difference between Igor's cold cloud top temperatures and the warm ocean surface waters that are powering it are greater than 170 degrees Fahrenheit!

The AIRS instrument is managed out of NASA's Jet Propulsion Laboratory in Pasadena, Calif. and NASA's Ed Olsen creates those stunning images.

At 11 a.m. EDT today, Sept. 14, Hurricane Igor was still a category 4 hurricane on the Saffir-Simpson scale with maximum sustained winds near 135 mph. It was located far from land, about 710 miles east of the Northern Leeward Islands, near 18.3 North and 52.3 West. It was moving west-northwest near 7 mph, and is forecast by NOAA's National Hurricane Center to turn toward the northwest on Wednesday. Igor's minimum central pressure is 945 millibars.

Although Igor is over 700 miles from the Northern Leeward Islands, large ocean swells will reach them today creating dangerous conditions at beaches. Large swells will reach Puerto Rico and the Virgin Islands later today and tomorrow. These dangerous surf conditions also create rip currents along the beaches.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
