NASA satellite sees western north Pacific Tropical Cyclone strengthening

24.07.2012
NASA satellite data has watched cloud temperatures drop in a low pressure system in the western North Pacific Ocean called System 92W, indicating that there's more uplift and power in the storm. That's a sign the storm is strengthening.

Infrared data gathered by NASA's Atmospheric Infrared Sounder (AIRS) instrument indicate cloud top temperatures as well as sea surface temperatures. NASA's Aqua satellite passed over System 92W on July 18, 19 and 20 and watched the low pressure area develop east of the Philippines, organize and move northeast of Luzon, Philippines by July 20.


This time series of infrared imagery from the AIRS instrument on NASA's Aqua satellite shows the progress of System 92W on July 18, 19 and 20. Purple areas indicate coldest cloud top temperatures, strongest storms and heaviest rainfall.

On Wednesday, July 18 at 1705 UTC (1:05 p.m. EDT/U.S.), System 92W's center east of Luzon, and there were several areas of strong convection (rising air that form thunderstorms that make up a tropical cyclone). They appeared disorganized in satellite imagery at that time, however.

On Thursday, July 19, AIRS data showed a much larger and more concentrated area of strong convection and thunderstorms. AIRS data revealed strong thunderstorms with cloud top temperatures colder than 220 kelvin (-63.6 F/-53.1C) and heavy rainfall over northeastern Luzon stretching east into the Philippine Sea.

On Friday, July 20, at 0441 UTC (12:41 a.m. EDT/U.S.) AIRS data revealed that the area of convection east of Luzon had expanded and strengthened. AIRS data also showed that the low-level circulation center was partially exposed, and that the strongest convection and largest area of showers and thunderstorms were southwest of the center. Northeasterly wind shear is pushing the strongest thunderstorms to that quadrant of the storm. By 0800 UTC (4 a.m. EDT), System 92W had moved to 18.0 North latitude and 124.3 East longitude. That's about 280 nautical miles northeast of Manila, Philippines.

The Joint Typhoon Warning Center forecasts System 92W to move west-northwest past northern Luzon and continue into the South China Sea over the next couple of days into an area with lower vertical wind shear. As System 92W moves over the weekend, northern Luzon can expect heavy rainfall and likely some localized flooding. If System 92W does organize into a tropical storm over the weekend, it would be named Vicente.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
