The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument flies onboard NASA's Aqua and Terra satellites and the MODIS instrument on each captured a storm when both satellites flew over them on August 21 after midnight (Eastern Daylight Time). The two MODIS images which featured Bolaven and Tembin over the Philippine Sea were combined by NASA's MODIS Rapid Response Team at the NASA Goddard Space Flight Center in Greenbelt, Md. to paint the entire tropical picture in the northwestern Pacific Ocean on August 21.
MODIS images from NASA's Terra and Aqua satellites on Aug. 21, 2012, at 04:45 UTC were combined to provide a complete picture of the two tropical troublemakers in the northwestern Pacific: Typhoon Tembin and Tropical Storm Bolaven.

Typhoon Tembin Tracking to Taiwan
Typhoon Tembin is also known as Typhoon Igme in the Philippines, where it is still the cause for active warnings on Aug. 21. Public storm warning signal #1 remains in effect for the Batanes group of islands on Aug. 21. At 0900 UTC (5 a.m. EDT) on Aug. 21, Typhoon Tembin had maximum sustained winds near 110 knots (126.6 mph/203.7 kmh). Typhoon-force winds extended out to 30 nautical miles (34.5 miles/55.5 km) from the center, while tropical-storm-force winds extended out 100 nautical miles (115 miles/185 km) from the center, making Tembin over 200 nautical miles (230 miles/370 km) wide.
Tembin was located about 325 nautical miles (374 miles/602 km) southeast of Taipei, Taiwan, near 21.0 North latitude and 125.4 East longitude. Although Tembin is currently moving to the north-northeast, the Joint Typhoon Warning Center forecasts Tembin to intensify and take a western turn and head across Taiwan on Thursday, Aug. 23. After crossing Taiwan, Tembin is forecast to make a second landfall east of Hong Kong. A Sea Warning and Typhoon Warning is already in effect for Taiwan, as heavy rain and rough seas are expected to affect eastern Taiwan by Wednesday, Aug.22. The Central Weather Bureau indicated that Tembin will likely make landfall in the Yilan, Hualien or Taitung counties on the eastern coast.
Tropical Storm Bolaven Poised to Strengthen
Tropical storm Bolaven's maximum sustained winds were near 55 knots (63.2 mph/102 kmh) and the Joint Typhoon Warning Center expects it to strengthen into a typhoon over the next several days. At 0900 UTC (5 a.m. EDT) on Aug. 21, Bolaven was located about 390 nautical miles (449 miles/722 km) south of Iwo To, near 18.4 North latitude and 140.4 West longitude. Bolaven is crawling to the west-northwest at 4 knots (4.6 mph/7.4 kmh).
Bolaven appears on MODIS imagery as a smaller storm than Tembin. While Tembin is over 200 nautical miles (230 miles/370 km) in diameter, Bolaven is just about 100 nautical miles (115 miles/185 km) in diameter.
Bolaven is strengthening and is expected to become a typhoon as it heads northwest. It is currently expected to pass to the north of Taiwan around Aug. 25-26, 2012.

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...
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...
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...
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...
