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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
