NASA sees large Tropical Storm Kai-tak headed for a landfall near Hong Kong

16.08.2012
Warnings are still in effect in the northern Philippines and now in Hong Kong, as Tropical Storm Kai-tak continues to drop heavy rainfall and move toward a landfall in China. NASA's Aqua satellite captured infrared data that shows a large area of strong thunderstorms that make up Kai-tak.

NASA's Aqua satellite captured infrared data on Kai-tak when it passed overhead on August 15 at 0517 UTC (1:17 a.m. EDT/1:17 p.m. local time, Hong Kong). Forecasters at the Joint Typhoon Warning Center noted that infrared satellite imagery shows the organization near the center of Kai-tak's tightly wrapped low-level-circulation center suffered some minor degradation during the early part of August 15.

The Atmospheric Infrared Sounder (AIRS) instrument that flies onboard NASA's Aqua satellite provides infrared data and showed a large area of cold cloud top temperatures (a sign of more uplift and strength in the storm) west of Kai-tak's center. The strongest thunderstorms and coldest cloud top temperatures stretched from northern Luzon, west into the South China Sea. Satellite data shows a lack of convection (rising air that forms the thunderstorms that make up the tropical storm) around the northern periphery of the storm.

The winds of Tropical storm Kai-tak, known in the Philippines as Helen, have increased to 55 knots (63 mph/102 kmh) on August 15. Kai-tak is located near 19.5 North latitude and 119.0 East longitude, about 320 nautical miles (368 miles/592.6 km) east-southeast of Hong Kong. Kai-tak is moving to the west-northwest near 17 knots (19.5 mph/31.5 kmh).

Kai-tak continues moving northwest and is passing over northern Luzon today, August 15, 2012. Warnings are still in effect in Luzon, the Philippines and now in effect in Hong Kong, China.

Current warnings in effect in the Philippines on August 15 include: Public storm warning signal #1 for the Luzon provinces of Benguet, Ifugao, Isabela, La Union, Northern Aurora, Mountain Province, Nueva Vizcaya, Quirino, and Pangasinan. In addition, Public storm warning signal #2 is in effect for these Luzon provinces: Apayao and Abra, the Batanes Group of Islands, Cagayan, Calayan, Babuyan Group of Islands, Kalinga and Ilocos North and South.

In Hong Kong, the Stand-by signal 1 is in force. After passing over the South China Sea, it will come ashore near Hong Kong at typhoon strength. Landfall is expected to occur near Hong Kong tomorrow, Thursday, August 16 near 1200 UTC (8 a.m. EDT/8 p.m. local time, Hong Kong). Forecasters at the Joint Typhoon Warning Center note that warm waters off-shore may cause Kai-tak to intensify to typhoon strength just before it makes landfall.

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...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
