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.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
