NASA sees hurricane-strength Tropical Cyclone Ita heading toward Queensland

11.04.2014

Tropical Cyclone Ita has been strengthening over the last two days and by April 10, Ita had become a major hurricane in the Coral Sea when NASA's Terra satellite passed overhead.

Ita's maximum sustained winds were near 115 knots/132 mph/213 kph on April 10 at 0900 UTV/5 a.m. EDT, making it a Category Four hurricane on the Saffir-Simpson scale. According to NOAA, the definition of a Category 4 storm affecting land is: "Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls.


On April 9, NASA's TRMM saw powerful storms in Ita's eye wall reached heights of over 14 km/8.7 miles. The tallest thunderstorm towers reached heights of over 16 km/9.9 miles high in a feeder band well to the northeast of Ita's eye.

Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months."

Ita's center was still at sea, centered near 12.5 south and 147.1 east, about 275 nautical miles north-northeast of Cairns, Australia. Ita was moving to the north-northeast at 9 knots/10/3 mph/16.6 kph and generating 30-foot/9.1 meter high waves.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a visible image of Tropical Cyclone Ita approaching Australia on April 10 at 00:25 UTC. The image showed a cloud-shrouded eye with a thick band of powerful thunderstorms around the center of circulation.

On April 9, Ita was seen twice by NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission satellite known as TRMM satellite. Ita's wind speeds increased from 65 knots/75 mph with TRMM's first flight overhead at 0536 UTC/1:36 a.m. EDT to 80 knots/92 mph when viewed again at 1528 UTC/11:28 p.m. EDT.

TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments captured data on Tropical Cyclone Ita's rainfall at 1528 UTC/11:28 a.m. EDT. TRMM PR data showed that a maximum rainfall rate of almost 163 mm/6.4 inches per hour was located in the eastern side of Ita's eye wall.

TRMM's Precipitation Radar (PR) instrument sliced through Ita's eye and those data were used to create a 3-D "cut-a-way" view. The image showed that powerful storms in Ita's eye wall reached heights of over 14 km/8.7 miles. The tallest thunderstorm towers reached heights of over 16 km/9.9 miles high in a feeder band well to the northeast of Ita's eye.

Ita is continuing to intensify as it moves west, south of Papua New Guinea. The Joint Typhoon Warning Center or JTWC expects the system to peak at 135 knots/155 mph/250 kph on approach to Queensland. JTWC also expects the system will veer sharply southeast on approach to the Australian coastline, and gradually weaken as it passes along the eastern coastline of Queensland. Ita will commence extra-tropical transitioning north of Brisbane.

Current warnings in Queensland are in effect between Lockhart River and Innisfail, extending inland to Kalinga, Laura, Mareeba and Chillagoe. A tropical cyclone watch is in force between Innisfail to Cardwell, extending inland.

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...
