NASA satellite video and images show Dora become a major hurricane

22.07.2011
A new image and video of major Hurricane Dora were released today from NASA's Goddard Space Flight Center in Greenbelt, Md.

Satellites provide a bird's eye view of a hurricane's eye, and NASA noticed Hurricane Dora's eye from several of them. Infrared imagery from NASA's Aqua satellite provided forecasters with a clear view of a cloud-free eye in hurricane Dora as she strengthens near Category 5 status today. Meanwhile the GOES-11 satellite captured a movie of Dora's intensification over the last two days that clearly shows a developing eye.

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured an infrared image of Hurricane Dora's cold cloud temperatures on July 21 at 09:05 UTC (5:05 a.m. EDT). The strongest thunderstorms and convection totally surrounded the very obvious, cloud-free eye.

The Geostationary Operational Environmental Satellite called GOES-11 provides continuous visible and infrared imagery of the western U.S. and eastern Pacific Ocean basin from its position in space. GOES-11 images were compiled into a movie that runs from July 19 at 14:30 UTC (10:30 a.m. EDT) when Dora was a tropical storm, to July 21 at 14:30 UTC (10:30 a.m. EDT) now that Dora is a major hurricane.

GOES satellites are operated by NOAA, and the NASA GOES Project located at NASA Goddard creates images and compiled them into the video of the storm. The animation includes sped up infrared and visible frames of data that were captured every 15 minutes from the GOES-11 satellite and squeezed down to 26 seconds.

At 11 a.m. EDT on July 21, 2011 Dora's maximum sustained winds were near 155 mph (250 kmh), right on the brink of Category 5 hurricane status. Fortunately, Dora's center is remaining at sea, and will continue to remain at sea as it moves to the northwest near 12 mph (19 kmh). It is expected to continue in that direction for the next couple of days and slow down.

Dora was centered near 17.1N and 106.9W, about 240 miles (390 km) south-southwest of Cabo Corrientes, Mexico. Minimum central pressure is 929 millibars.

Dora is far enough off the coast so that there are no watches and warnings over land. However, Dora is sending large ocean swells against the beaches of western Mexico today. Those large, rough, ocean swells will affect the coast over the next couple of days, and will also begin affecting the southern Baja California coast.

The National Hurricane Center expects some weakening by tonight and a rapid weakening on Friday as Dora starts battling wind shear and moves into cooler waters.

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...
