NASA sees fading post-Tropical Cyclone John's warmer cloud tops

06.09.2012
Post-tropical cyclone John has been "flushed" out of existence in the eastern Pacific Ocean, and infrared NASA imagery revealed warmer cloud top temperatures and virtually no precipitation from John's remnants on Sept. 4.

When NASA's Aqua satellite flew over post-tropical storm John on Sept. 4 at 21:23 UTC (5:23 p.m. EDT) the Atmospheric Infrared Sounder (AIRS) instrument revealed that cloud top temperatures in the storm had warmed over the previous 24 hours.


NASA AIRS infrared data on Sept. 4 at 5:23 p.m. EDT showed a circular swirl of clouds in post-tropical storm John where temperatures were around (yellow) 270 kelvin (26.3 F/-3.1 C), which are warm in terms of cloud top temperatures for thunderstorms.

AIRS data also showed there was one very tiny area of convection (rising air that forms the thunderstorms that make up a tropical cyclone) in the southwestern quadrant of the entire low pressure area.

The AIRS infrared data showed a circular swirl of clouds where temperatures were around 270 kelvin (26.3 F/-3.1 C), which are warm in terms of cloud top temperatures for thunderstorms. When cloud top temperatures reach the AIRS data threshold of -63F/-52C, they are considered strong thunderstorms.

The last advisory on John was issued by the National Hurricane Center on Sept. 4 at 2100 UTC (5 p.m. EDT), just before the AIRS image was captured by NASA's Aqua satellite. The 5 p.m. advisory put John's center about 505 miles west-northwest of Cabo San Lucas, Mexico, near 24.3 North and 117.7 West.

John's maximum sustained winds were near 35 mph (55 kmh) and weakening. The remnants of John were moving to the northwest at 12 knots (13.8 mph/22.2 kmh) as the low pressure area continued to weaken. John is expected to dissipate later today.

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...
