NASA satellite indicates Tropical Storm Prapiroon's rains mostly south of center

17.10.2012
Tropical Storm Prapiroon is still meandering in the western north Pacific Ocean, and NASA's TRMM satellite noticed that dry air and wind shear are adversely affecting rainfall north of the storm's center.

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite flew above Prapiroon when it was a typhoon on Oct. 15, 2012 at 0632 UTC (2:32 a.m. EDT). Prapiroon's sustained wind speeds had dropped to 70 knots (~81 mph) with a large and ragged eye being its dominant feature. TRMM's Microwave Imager (TMI) data indicated that the most intense rain bands south of Prapiroon's eye were dropping rain at a rate of about 30-40 mm/hour (~1.2 to 1.6 inches).

The erosion of the rainfall was still happening in satellite imagery on Oct. 16, and the bulk of the showers were occurring south of the center. Dry air has also been affecting the north side of the storm, and dry air absorbs the moisture that helps create the clouds and thunderstorms that make up the storm. The bands of showers and thunderstorms in the southern quadrant, however, are still strong.

On Oct. 16, 2012 at 1500 UTC, Tropical Storm Prapiroon, known as "Nina" in the Philippines, had maximum sustained winds near 60 knots (69 mph/111 kph). It was located near 22.2 North latitude and 129.3 East longitude, about 260 nautical miles (299 miles/481.5 km) south-southeast of Kadena Air Base, Okinawa, Japan. It was still moving slowly, just 5 knots (5.7 mph/9.2 kph) to the west. Prapiroon is still meandering until a mid-latitude shortwave trough (elongated area of low pressure) moving into central China can push it to the northeast.

Prapiroon is not expected to strengthen before it begins moving to the northeast on Oct. 17. The Joint Typhoon Warning Center forecasts the storm to become extra-tropical thereafter.

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.
