NASA examines powerful Tropical Cyclone Emeraude's winds, clouds

18.03.2016

Tropical Cyclone Emeraude continued to strengthen in the Southern Indian Ocean as NASA captured infrared temperature data of the storm's clouds and measured its surface wind speed.

Emeraude is in the southern part of the Indian Ocean over 1,000 km from the nearest land area. It is roughly south of Sri Lanka and west of Java.


NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Cyclone Emeraude at hurricane strength on March 17, showing a small eye in the center of circulation.

The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite provided infrared temperature data on Emeraude on March 16 sat 07:59 UTC (3:59 a.m. EDT).

AIRS revealed bands of thunderstorms wrapping into the center of circulation from the east and southwest had cloud top temperatures as cold as minus 63 Fahrenheit/minus 53 Celsius. Temperatures that cold indicated strong storms high into the troposphere with the potential to generate heavy rain.

NASA's RapidScat instrument that flies aboard the International Space Station measures Earth's ocean surface wind speed and direction over open waters. When the ISS flew over Emeraude on March 16 RapidScat saw strongest sustained winds approaching 30 meters per second (67.1 mph/108 kph) and the storm was intensifying rapidly.

Emeraude intensified from a tropical storm on March 16 into a major hurricane by March 17.

The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Cyclone Emeraude at hurricane strength on March 17 at 0755 UTC (3:55 a.m. EDT) showing a small 14 nautical-mile-wide (16.1 miles/25.9 km) eye in the center of circulation. At the time Suomi NPP passed over Emeraude, it was a Category 4 hurricane on the Saffir-Simpson Wind Scale.

At 0900 UTC (5 a.m. EST) on March 17, 2016 Tropical Cyclone Emeraude's maximum sustained winds had increased to 125 knots (143.8 mph/231.5 kph) and still intensifying. It was located near 10.4 degrees south latitude and 84.0 degrees east longitude, about 710 nautical miles (817 miles/1,316 km) east-southeast of Diego Garcia. Emeraude was moving slowing to the west-northwest at 2 knots (2.3 mph/3.7 kph).

By March 17, wind data showed tropical-storm-force winds were occurring up to 90 nautical miles (103.6 miles/166 km) from the center and hurricane-force winds within 30 nautical miles (34.5 miles/55.5 km) of the eye.

The Joint Typhoon Warning Center expects Emeraude's maximum sustained winds to peak around 135 knots (155.4 mph/250 kph) on March 18 before a weakening trend begins. The storm is also expected turn east-southeast before turning southwest on March 21 all while remaining over open waters of the Southern Indian Ocean.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
