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: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
