NASA's TRMM satellite sees Tropical Cyclone 19P form

08.03.2013
NASA's Tropical Rainfall Measuring Mission satellite noticed areas of heavy rainfall in low pressure System 92P hours before it became the nineteenth tropical cyclone of the Southern Pacific Ocean.

NASA's TRMM satellite captured a look at the rainfall rates within low pressure System 92P on March 7 at 0023 UTC (March 6 at 7:23 p.m. EST), just hours before it became Tropical Cyclone 19P (TC 19P). TRMM data indicated that heavy rain was falling at a rate of 2 inches/50 mm per hour around the center of circulation, and that some of the thunderstorms were powerful as they topped heights of 9.3 miles (15 kilometers). Bands of thunderstorms around the storm expanded, strengthened and wrapped tighter around the storm's center today, March 7, according to the Joint Typhoon Warning Center (JTWC).

On March 7 at 1200 UTC (7 a.m. EST) the intensifying tropical storm had maximum sustained winds near 35 knots (40 mph/64 kph). TC 19P was centered near 15.4 south latitude and 156.9 east longitude about 660 nautical miles (759.5 miles/1,222 km) northwest of Noumea, New Caledonia. TC19P was moving to the east-northeast at 11 knots (12.6 mph/20.3 kph).

JTWC forecasters expect TC 19P to strengthen and curve to the southeast, affecting New Caledonia by March 11.

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: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

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,...
