NASA's infrared look at strengthening Typhoon Chan-Hom

07.07.2015

During the early morning hours on July 6, Chan-Hom was a strong tropical storm. Infrared data from NASA's Aqua satellite showed very powerful thunderstorms that hinted at intensification, and later in the day, Chan-Hom became a typhoon.

The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite gathered infrared temperature data on Chan-Hom when it was a Tropical Storm on July 6 at 04:29 UTC (12:29 a.m. EDT).

The coldest thunderstorm cloud tops measured were near -63 Fahrenheit or -52 Celsius. Cloud top temperatures that cold are high into the troposphere and capable of generating heavy rain.

The Joint Typhoon Warning Center (JTWC) looked at animated infrared imagery that showed a slight improvement in organization with a marked increase in central convection (rising air that forms the thunderstorms that make up a tropical cyclone). Other satellite imagery showed that there were tightly-curved bands of thunderstorms wrapping into a defined center.

Between 0900 UTC and 1500 UTC today, July 6, Chan-Hom's maximum sustained winds increased from 60 knots (69 mph/111 kph) to 65 knots (75 mph/120 kph) bringing it to typhoon strength.

It was centered near 18.1 North latitude and 138.9 East longitude, about 825 nautical miles southeast of Kadena Air Force Base, Guam. Chan-Hom has tracked west-northwestward at 14 knots (16 mph/26 kph).

Chan-Hom is intensifying as it moves northwest through the Northwestern Pacific Ocean. The JTWC forecasts the storm to continue to strengthen over the next three days and expected to peak as a Category 4 typhoon on the Saffir-Simpson Wind Scale, with maximum sustained winds nearing 130 knots (149.6 mph/240.8 kph). The storm is forecast to pass between Ishigakjima and Kadena islands on July 9 before making landfall in eastern China as a typhoon.

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...

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...
