3 NASA satellites see wide-eyed Cyclone Haruna

21.02.2013
Cyclone Haruna strengthened into a cyclone and quickly developed an eye that became apparent on visible and infrared imagery from NASA's Aqua satellite. NASA's TRMM satellite analyzed Haruna's heavy rainfall, and NASA and NOAA's Suomi NPP satellite captured a night-time image that verified the strongest areas of the storm.

On Feb. 20 at 1111 UTC (6:11 a.m. EST/U.S.) the AIRS instrument aboard NASA's Aqua satellite captured this infrared image of Tropical Cyclone Storm Haruna. The area of strongest thunderstorms circled the eye and had cloud top temperatures colder than -63F (-52C). Those cold cloud top temperatures indicated strong storms with heavy rainfall, which was verified by NASA's Tropical Rainfall Measuring Mission (TRMM) satellite.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies with AIRS aboard NASA's Aqua satellite captured a visible image of Tropical Storm Haruna on Feb. 20 at 1115 UTC (6:15 a.m. EST) that revealed its large eye.

NASA's TRMM satellite flew above intensifying tropical storm Haruna on February 20, 2013 at 0717 UTC (2:17 a.m. EST). A rainfall analysis was created using data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments overlaid on a combination visible/infrared image from the Visible and InfraRed Scanner (VIRS). The analysis showed that Haruna had become much better organized since Feb. 19 and developed intense bands of rainfall circling the cyclone's center. Some rain in powerful storms on the northern edge of Haruna's center was found by TRMM PR to be falling at a rate of over 108 mm (~4.25 inches) per hour.
NASA's TRMM Precipitation Radar (PR) was used to create a 3-D image that sliced through tropical storm Haruna's center. TRMM data showed that towering thunderstorms on the northern edge of Haruna's center were over 14.25 km (~8.85 miles) high.

NASA-NOAA's Suomi NPP satellite captured infrared night-time data of Cyclone Haruna on Feb. 19 at 2303 UTC (2 a.m. local time Madagascar on Feb. 20). The data was false-colored at the University of Wisconsin Madison and showed the coldest cloud top temperatures and heaviest rainfall north of the center of circulation, verifying NASA's TRMM satellite data.

At 1500 UTC (10 a.m. EST) on Feb. 20, Haruna reached hurricane (or cyclone)-force with maximum sustained winds near 70 knots (80 mph/129.6 kph). Haruna is centered near 22.1 south latitude and 40.7 east longitude, about 400 nautical miles (460 miles/741 km) west-southwest of Antananarivo, Madagascar. Haruna is moving to the west at 4 knots (4.6 mph/7.4 kph) and generating 25-foot-high (7.6 meter-high) waves.

Forecasters at the Joint Typhoon Warning Center expect Haruna to make a brief landfall near Androka in the southwestern part of Madagascar as the storm heads southeast into the open waters of the southern Indian Ocean.

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...
