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: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
