NASA's TRMM Satellite measures Cyclone Ului's Australian rainfall from space

23.03.2010
NASA and the Japanese Space Agency's Tropical Rainfall Measuring Mission or TRMM satellite can estimate rainfall from space. TRMM is used to monitor tropical rainfall around the world, and can also calculate flood potential. TRMM data was used to create an animation of Tropical Cyclone Ului's track as it approached and made landfall in Queensland, Australia this weekend.

The TRMM animation of rainfall indicated that between 130 mm and 179 mm (5.1 and 7.0 inches) of rainfall fell in areas west of Collinsville, Queensland from Ului's landfall. TRMM data, along with information from other satellites, allows researchers to see how much rain is falling over most of the world every three hours and map areas of potential flooding. Maps that show areas of potential floods use precipitation radar data and high resolution measurements of water content of clouds made by microwave radiometers.

Those rainfall maps were made into a seven-day "movie loop" that allows users to track storms as they travel over land and oceans around the globe. The rainfall animations are developed in the Laboratory for Atmospheres of the NASA Goddard Space Flight Center, Greenbelt, Md. by the TRMM precipitation research team.

About 130mm (5.1 inches) or rainfall was estimated by TRMM at -20.38 latitude and 148.13 longitude, in Bogie, Queensland, Australia, near the Mount Aberdeen State Park. In Springlands, west of Collinsville, Queensland, near -20.88 latitude and 148.88 longitude, TRMM estimated a rainfall of 136mm (5.3 inches). At Mount Wyatt, 163mm (6.4 inches) of rain were estimated to have fallen, and southeast of Swan's Lagoon and Millaroo, TRMM estimated that 179mm (7.0 inches) of rain had fallen from Ului.

On March 20, Ului was a tropical storm with maximum sustained winds near 64 mph about 385 miles east of Cairns, Australia near 19.9 South and 151.7 East. Later in the day it brought sustained winds between 92-109 mph to Hamilton Island off Proserpine. By 2100 UTC (5 p.m. EDT) that day, Ului was 260 miles southeast of Cairns, Queensland, Australia with sustained winds near 52 mph (45 knots) . However, it briefly re-intensified with sustained winds near 109 mph before making landfall near Bowen at Airlie Beach.

Reports indicated that about 60,000 homes lost power and there was a lot of destruction to trees, houses, boats, power lines and sugar cane crops - a major crop in the region.

Ului headed west toward the Northern Territory where its rains have ended, and it is bringing only increased cloud cover and higher humidity. The Northern Territory may also see some isolated showers. As of March 22, all tropical cyclone watches and warnings were discontinued.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

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,...
