The GPM satellite showed the effects of wind shear and waning rainfall rates in Extra-tropical Cyclone Joalane as it was moving in a southeasterly direction through the Southern Indian Ocean.
The Global Precipitation Measurement (GPM) core observatory satellite had a last look at the remnants of Tropical Cyclone Joalane on April 14, 2015 at 1135 UTC (4:35 p.m. local time/7:35 a.m. EDT/U.S.).
GPM's Microwave Imager (GMI) instrument found very little rainfall around Joalane's center and light to moderate rainfall in bands on the outer edges of the rapidly weakening tropical cyclone.
At NASA's Goddard Space Flight Center in Greenbelt, Maryland, reflectivity data derived from the Ku band on GPM's dual frequency radar was used to create a three-dimensional image of the extra-tropical cyclone.
The 3-D image showed cloud tops were tilted toward the south, clearly indicating how strongly vertical shear was affecting the rapidly weakening tropical cyclone. GPM data showed that Joalane's highest storm tops were as high as 9.37 km (5.8 miles) in rain bands south of Joalane's center of circulation.
Joalane continued to weaken and is expected to dissipate in a day or two.

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...

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...
