Tropical Depression 21W Forms, Philippines Under Warnings

27.11.2014

The Tropical Rainfall Measuring Mission or TRMM satellite provided rainfall data as Tropical Depression 21W was making landfall in the southern Philippines on Nov. 26.

TRMM revealed areas of heavy rainfall in fragmented bands east of the center of circulation, where rain was falling at more than 1 inch (25 mm) per hour.

TRMM rainfall data was overlaid on infrared data from the Japan Meteorological Agency's MTSAT-1 satellite that showed Tropical Depression 21W's (TD21W) clouds extended from western Mindanao, east into the Philippine Sea.

On Nov. 26, there were a number of warnings in effect for the Philippines. Public storm warning signal #1 was in effect for the province of Luzon that includes: Palawan and the Calamian Group of Islands. In Visayas: Southern Leyte, Bohol, Southern Cebu Including Cebu City, Negros Oriental, Southern Negros Occidental and Siquijor. In the province of Mindanao:

Surigao del Norte including Siargao Island, Surigao del Sur, Agusan del Norte & Sur, Dinagat Province, Camiguin, Misamis Oriental & Occidental, Bukidnon and Zamboanga del Norte.

At 1500 UTC (10 a.m. EST), TD21W was centered near 8.7 north longitude and 125.4 east latitude. That's about 468 nautical miles (538.6 miles/866.7 kph) southeast of Manila, Philippines. Maximum sustained winds were near 30 knots (34.5 mph/55.5 kph). TD21W is moving to the west at 9 knots (10.3 mph/16.6 kph).

TD 21W is forecast to continue tracking westward along the southern edge of a sub-tropical ridge of high pressure which is located to the north of the depression and oriented east-west. The Joint Typhoon Warning Center forecasts TD21W to move over northern Mindanao late on Nov. 26 and weaken. By Nov. 27, TD21W is expected to emerge into the Sulu Sea where it is expected to strengthen.

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.
