Tropical Cyclone Helen headed for landfall in India

21.11.2013
Tropical Cyclone 04B has strengthened and been renamed "Helen" as it slowly nears landfall in southeastern India.

On Nov. 20 at 1200 UTC/7 a.m. EST, Tropical Cyclone Helen had maximum sustained winds near 50 knots/57.5 mph/92.6 kph. It was centered near 15.5 north and 83.9 east, about 499 nautical miles/574.2 miles/924.1 km south-southwest of Calcutta, India. Helen was crawling to the northwest at 1 knot/1.1 mph/1.8 kph. A mid-level subtropical ridge (elongated area) of high pressure is expected to slowly build east of Helen and steer the storm on a more western track in the next day.


Visible/short wave infrared data from ESA's METEO-7 satellite and rainfall data from NASA's TRMM satellite was combined to create this image of Tropical Cyclone Helen on Nov. 20.

Current warnings are in effect for fishermen along the coasts of Andhra Pradesh, who are advised to return to shore.

Animated multispectral satellite showed a resurgence of deep convection over the low-level center of circulation. Satellite data also showed that the band of thunderstorms that appeared strong to the north has weakened and become fragmented. Visible/short wave infrared data from ESA's METEO-7 satellite and rainfall data from NASA's Tropical Rainfall Measuring Mission or TRMM satellite was combined at the Naval Research Laboratory to create a composite image of the storm on Nov. 20. The image showed the clouds associated with Helen were mostly still over the open waters of the Arabian Sea, and that south of the center, light rainfall was occurring.

Helen is expected to intensify to 60 knots/69.0 mph/111.1 kph over the next two days and weaken before landfall. Helen is forecast to pass just south of the Yelichetladibba Palem and Nachugunta Reserved Forests in Andhra Pradesh, located in the coastal plain of Krishna Delta. Helen is expected to make landfall in the vicinity of Chinnaganjam in southeastern India.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

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...
