Tropical Depression Dokuri weaker, but still potent

29.06.2012
Tropical Storm Dokuri weakened into a tropical depression today, but NASA infrared satellite imagery is still showing some areas of strong convection and thunderstorms in the storm and they're being pushed away from the center.

NASA's Aqua satellite passed over Tropical Storm Dokuri on June 27 on 0435 UTC (12:35 a.m. EDT). Infrared data from the Atmospheric Infrared Sounder (AIRS) instrument onboard indicated there were still some strong showers and thunderstorms within the system. Those cloud top temperatures were colder than -63 Fahrenheit (-52 Celsius), indicating strong uplift in the atmopshere, and thunderstorms within Dokuri that have the capability for heavy rainfall.

Infrared data shows a fully-exposed low level-circulation center. The strongest convection (rising air that creates thunderstorms that make up the system)are being pushed to the southwest due to strong northeasterly vertical wind shear.

Warnings are up in the Philippines as Doksuri (known there as Dindo) continues to move north of Luzon today. Public storm warning signal #1 is in effect in Abra, Kalinga, Isabela, Ilocos Sur, Mt. Province, Ifugao, La Union, Benguet, Pangasinan, Nueva Vizcaya and Quirino. Public storm warning signal #2 is also in effect for Cagayan, Calayan Group of Islands, Babuyan Group of Islands, Batanes Group of Islands, Apayao, Ilocos Norte.

On June 28, 2012 at 1500 UTC (11 a.m. EDT), Tropical Storm Doksuri had maximum sustained winds near 35 knots. It was located approximately 335 nautical miles north of Manila, Philippines, near 20.4 North and 120.7 East. It was moving to the west-northwestward at 17 knots. The strongest convection and thunderstorms were located over northern Luzon at this time, and are moving off the northwestern coast of the Philippines.

Doksuri has weakened as it passes to the north of Luzon. Doksuri is expected to continue tracking west and make landfall near Hong Kong in two days.

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...
