NASA and the Japan Aerospace Exploration Agency's GPM satellite provided scientists with a look "under the hood" of Tropical Cyclone Joalane's clouds at the rate in which rain was falling throughout the storm.
The Global Precipitation Measurement or GPM core observatory satellite flew over intensifying cyclone Joalane in the South Indian Ocean on April 6, 2015 at 0406 UTC (12:06 a.m. EDT). GPM's Microwave Imager (GMI) found that intense convective thunderstorms within Joalane were dropping rain at a rate of over 63 mm (2.5 inches) per hour.
Cyclone Joalane was located northeast of Mauritius at the time of that GPM pass. At NASA's Goddard Space Flight Center in Greenbelt, Maryland a 3-D view of Joalane's vertical precipitation structure was constructed using GPM's Radar (Ku Band) data.
This cross section showed that several towering thunderstorms near Joalane's center were reaching heights of over 15 km (9.3 miles). A few storm tops in a strong rain band south of Joalane's center were found reaching even higher to altitudes of 17.4 km (10.8 miles).
Two days later, on April 8 at 09:35 UTC (5:35 a.m. EDT) the MODIS instrument that flies aboard NASA's Aqua satellite captured a visible light image of Tropical Cyclone Joalane that showed the storm maintained an eye that it developed the previous day. Bands of thunderstorms wrapped into the center of circulation. The largest, thickest band of thunderstorms appeared on the eastern side of the center.
At 1500 UTC (11 a.m. EDT) on April 8, 2015, Tropical Cyclone Joalane's maximum sustained winds were near 90 knots (103.5 mph/166.7 kph). It was centered near 15.6 south and 64.9 east, about 624 nautical miles (718.1 miles/1,156 km) east-northeast of St. Denis.
Joalane is moving to the southeast at 9 knots (10.3 mph/16.6 kph). At that time, there were no tropical cyclone warnings in effect for Rodrigues Island.
Tropical Cyclone Joalane has intensified and the Joint Typhoon Warning Center forecast a southeastern track through the Southern Indian Ocean. Joalane is expected to weaken to a tropical storm by April 13.

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...
