NASA satellite sees Tropical Storm Fami form, fast and furious

03.02.2010
NASA's Aqua satellite caught the thirteenth tropical cyclone in the southern Indian Ocean form very quickly. In 12 hours a low grew into a tropical storm named Fami and made a fast landfall in Madagascar around 1 a.m. ET (0600 UTC) today, February 2.

At 1 a.m. ET (0600 UTC), Tropical Storm Fami had maximum sustained winds near 46 mph (40 knots) and was located in southern Madagascar, about 235 nautical miles west-southwest of Antananarivo, Madagascar. That's near 21.2 South and 43.8 East. Fami is moving east-southeast near 9 mph (8 knots).

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite has the capability to create visible, infrared and microwave images of tropical cyclones. AIRS infrared and microwave images both showed very high, powerful thunderstorms in Fami, even now that it has made landfall. A microwave image was created combining AIRS and Advanced Microwave Sounding Unit (AMSU) data. AMSU is another instrument that flies on NASA's Aqua satellite.

The microwave image revealed that despite being over land, Fami has developed an eye feature developing in the mid- to upper-levels of the system. That is an indication that the storm is maintaining its strength, and likely feeding on tropical moisture from the warm waters that surround southern Madagascar. The microwave image also revealed cold areas in the storm that indicate ice in cloudtops and heavy precipitation. Around the eye are the coldest cloud temperatures, as cold as -63F. Microwave data suggests cloud heights to the 200 millibar level, near the tropopause.

Fami's track over the next two days and strength is one that forecasters are still pondering. One computer model forecasts that the friction caused by Fami's track over land will cause its dissipation, while another computer model (the ECMF) brings Fami back into the open ocean, then dissipating from increasing wind shear. Forecasters are watching the storm as it continues to track over land.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

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...
