In a series of three infrared images from the period of May 19-22, 2011, NASA's Atmospheric Infrared Sounder (AIRS) instrument revealed the strengthening of Tropical Storm Songda. The area with strongest convection has expanded and organized over that time. That area of strongest convection has the coldest, highest thunderstorm cloud tops near -63 F/-52C, and heaviest rainfall.
This series of three infrared images shows the strengthening of Tropical Storm Songda over the period of May 19-22, 2011. Notice that the area with strongest convection (purple) has expanded over that time. That area has the coldest, highest thunderstorm cloud tops near -63 F/-52C, and heaviest rainfall. Over those four days, Songda took on a more rounded shape. Credit: NASA/JPL, Ed Olsen
The time series of imagery over those four days also shows that Songda took on a more rounded shape as it continued to strengthen from a tropical depression to a tropical storm. Today, May 23, satellite imagery shows a strong band of deep convection is persisting along the southern edge of Songda.
On May 21, Tropical Storm 04W still had maximum sustained winds near 40 mph (35 knots/64 kmh). On Sunday, May 22, the maximum sustained winds increased to 52 mph (45 knots/83 kmh) and the storm was renamed "Tropical Storm Songda." At that time the center of the storm was near 10.0 N and 136.4 E, or 190 miles north-northeast of Palau. By 2100 UTC on May 22, Songda's winds again increased to 55 knots as it continued moving north-northwest.
On May 23, Songda's maximum sustained winds have again increased and are now clocked at 69 mph (60 knots/111 kmh). Tropical storm-force winds extend out 100 miles (161 km) from the center. Further strengthening is expected by the forecasters at the Joint Typhoon Warning Center. Songda's center was located about 295 miles (475 km) northwest of Palau, near 11.5 North and 131.8 East, and it was moving west-northwest near 12 mph (10 knots/~18 kmh). Songda is kicking up high waves in the Northwestern Pacific, up to 22 feet (6/7 meters) high.
Songda is expected to continue intensifying over the next couple of days, but its center is forecast stay offshore from Luzon, Philippines and track east of land. However, the western side of the storm is expected to bring gusty winds, heavy rainfall and rough surf to Luzon over the next couple of days as it approaches and sweeps north toward Taiwan.

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...
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...
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...

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.
