Second only south Atlantic tropical storm: 90Q, moving away from Brazil

12.03.2010
Tropical Storm 90Q is the second known tropical cyclone to form in the cooler South Atlantic Ocean, and two NASA satellites confirm it is now moving away from Brazil's coast. The first tropical cyclone ever seen in recorded history in the Southern Atlantic was called "Catarina" in 2004.
The Naval Research Laboratory has provided information on the system, although they will not issue a formal tropical cyclone declaration because the Southern Atlantic is not currently covered by a Regional Specialist Meteorological Center (because tropical cyclones typically don't appear there), however, that may change in the future.

At 0845 UTC (3:45 a.m. ET) today, March 11, Tropical Storm 90Q had maximum sustained winds near 46 mph (40 knots). It was located about 325 miles east of Puerto Alegre, Brazil in the waters of the South Atlantic Ocean near 30.0 South latitude and 45.8 West longitude.
On Wednesday, March 10, the Tropical Rainfall Measuring Mission, or TRMM satellite had a fairly good pass this over Tropical Storm 90Q in the morning hours and showed some heavy rainfall, falling at a rate as much as 2 inches per hour on the storm's southeastern side. TRMM satellite data was used at NASA's Goddard Space Flight Center in Greenbelt, Md. to create a 3-D image of 90Q. The image showed some fairly high thunderstorm tops near the center of the storm reaching to heights above 12.5 km (over 41,010 feet), which corresponds with the areas of heavy rain. The TRMM satellite is managed by both NASA and the Japanese Space Agency, JAXA.

Early today, March 11, the Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured an infrared image of 90Q. The infrared image showed some high, cold thunderstorms in the center of the storm, confirming strong convection in the storm.

"The only other tropical cyclone known to have occurred in the Southern Atlantic Ocean developed in March, 2004," said Hal Pierce, meteorologist on the TRMM satellite team at NASA Goddard. "That's when a hurricane called "Catarina" made landfall on March 28, 2004 near the town of Torres in the southern Brazilian state of Santa Catarina (thus, the storm's name). It was the first "hurricane" ever observed by satellite in the south Atlantic." One agency in Brazil also issued warnings on the storm calling it "1-T Alfa."

Tropical Storm 90Q will continue moving in a general easterly direction away from the Brazilian coast and weaken before being absorbed by a mid-latitude cold front this weekend.

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,...
