NASA sees important cloud-top temperatures as Tropical Storm Malakas heads for Iwo To

24.09.2010
NASA's Aqua satellite has peered into the cloud tops of Tropical Storm Malakas and derived just how cold they really are, giving an indication to forecasters of the strength of the storm.

The Atmospheric Infrared Sounder instrument, known as AIRS has the ability to determine cloud top and sea surface temperatures from its position in space aboard NASA's Aqua satellite. Cloud top temperatures help forecasters know if a storm is powering up or powering down.

When cloud top temperatures get colder it means that they're getting higher into the atmosphere which means the "uplift" of warm, moist air is stronger and it will form stronger thunderstorms (that power a tropical cyclone). When cloud-top temperatures warm up it means that the cloud tops are lower than they were before, indicating that the storm is weakening.

When the Aqua satellite passed over Malakas from space on Sept. 23 at 0405 UTC (12:05 a.m. EDT) the AIRS instrument took the temperature of the cloud tops in the storm and found them to be as cold as or colder than -63 Fahrenheit throughout a very large area within Tropical Storm Malakas, indicating the storm had a good amount of energy powering it. Infrared imagery also showed an eye with thunderstorms banding around it (circling it), and convection (and thunderstorms) re-building over the system, which indicates strengthening.

The Joint Typhoon Warning Center is the organization that forecasts tropical cyclones in the northwestern Pacific Ocean, and they've been right on track with Tropical Storm Malakas' forecast, much to the disappointment of the residents of the Japanese island of Iwo To. That's where Malakas' center is expected to pass very closely near later tonight (Eastern Time/U.S.).

On Sept. 23 at 1500 UTC (11 a.m. EDT/midnight Sept. 24 local time at Iwo To), Malakas had maximum sustained winds near 69 mph (4 mph under typhoon strength). It was moving north at 14 mph toward Iwo To, Japan. It was located about 170 nautical miles south of the island, near 22.6 North and 140.9 East. Malakas is kicking up 27-foot high seas as it tracks north.

The center of Malakas is forecast to be closest to the island of Iwo To at 0000 UTC (about 9 a.m. Local time) on Sept. 24 (8 p.m. EDT on Sept. 23).

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:...

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,...
