GOES-13 sees an extraordinarily early Atlantic low in the tropics

21.04.2011
Hurricane season doesn't start in the Northern Atlantic Ocean until June 1, but a low pressure system in doesn't seem to want to follow the calendar. There's a low pressure area with a small chance for development north-northeast of Puerto Rico, and the GOES-13 satellite captured a visible image of the storm.

The National Hurricane Center (NHC) issued a Special Tropical Weather Outlook today, April 20, that noted the low pressure area was located about 460 miles northeast of San Juan, Puerto Rico at 3:35 p.m. EDT. The NHC noted that slow development is possible over next couple of days. The low is moving west -northwest at 10mph.

The image was created using satellite imagery was captured on April 20 at 17:45 UTC (1:45 p.m. EDT) from the Geostationary Operational Environmental Satellite (GOES-13). Although it is not easy to pick out the center of circulation in the image, it is located to the west of the largest area of clouds.

GOES satellites are operated by the National Oceanic and Atmospheric Administration. The image was created by NASA's GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md.

The NHC gives this low a 20 percent chance of development into a sub-tropical or tropical storm over the next two days before it hits wind shear, which will weaken it.

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: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

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.
