NASA Satellite Catches Australia's Newborn Tropical Storm Edna and Stubborn Fletcher

05.02.2014
Northeastern Australia has been watching two tropical low pressure areas over the last several days, and NASA's Aqua satellite captured both in one infrared image. Tropical Storm Edna developed on February 4, while Fletcher, known also as System 94P continued to have a medium chance for development.

On February 3 at 15:53 UTC/10:53 a.m. EST, NASA's Aqua satellite passed over Queensland, Australia and the AIRS or Atmospheric Infrared Sounder instrument captured infrared data on both storms. System 94P/Fletcher was in the Gulf of Carpentaria and over the Northwest region of Queensland, while newborn Edna formed in the South Pacific Ocean east of Queensland.


This infrared image of Tropical Storm Edna was taken by NOAA's polar orbiting satellite, NOAA-19 on Feb. 4 at 1443 UTC/9:43 a.m.

Tropical Storm Edna Moving Toward New Caledonia

System 93P strengthened between February 3 and 4 into Tropical Depression 12P and then Tropical Storm Edna, northwest New Caledonia. By 1500 UTC/10 a.m. EST Edna was about 392 nautical miles northwest of New Caledonia, near 17.2 south latitude and 161.5 east longitude. Edna had maximum sustained winds near 35 knots/40 mph/62 kph. It was moving to the southeast at 19 knots/21.8 mph/35.1 kph.

NASA's AIRS data showed very cold cloud top temperatures in powerful thunderstorms within Edna that have the potential for heavy rainfall. Infrared data also showed that Edna's circulation has consolidated and convection has deepened/strengthened with bands of thunderstorms, mostly north of the center, were wrapping more tightly into the low-level center of circulation.

AIRS data also showed that sea surface temperatures were around 28C/82.4F, warm enough to contribute to strengthening the system. Sea surface temperatures need to be at least 26.6C/80F in order for a tropical cyclone to maintain intensity. Warmer temperatures than that can help in increased evaporation with the formation of thunderstorms that make up a tropical cyclone. However, as Edna continues tracking southward, the storm will run into cooler sea surface temperatures that will squelch any significant intensification.

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...
