NASA analyzes rainfall in Tropical Cyclone Joalane

09.04.2015

NASA and the Japan Aerospace Exploration Agency's GPM satellite provided scientists with a look "under the hood" of Tropical Cyclone Joalane's clouds at the rate in which rain was falling throughout the storm.

The Global Precipitation Measurement or GPM core observatory satellite flew over intensifying cyclone Joalane in the South Indian Ocean on April 6, 2015 at 0406 UTC (12:06 a.m. EDT). GPM's Microwave Imager (GMI) found that intense convective thunderstorms within Joalane were dropping rain at a rate of over 63 mm (2.5 inches) per hour.


On April 8 at 09:35 UTC (5:35 a.m. EDT) NASA's Aqua satellite captured this visible light image of Tropical Cyclone Joalane that showed the storm maintained its eye.

Cyclone Joalane was located northeast of Mauritius at the time of that GPM pass. At NASA's Goddard Space Flight Center in Greenbelt, Maryland a 3-D view of Joalane's vertical precipitation structure was constructed using GPM's Radar (Ku Band) data.

This cross section showed that several towering thunderstorms near Joalane's center were reaching heights of over 15 km (9.3 miles). A few storm tops in a strong rain band south of Joalane's center were found reaching even higher to altitudes of 17.4 km (10.8 miles).

Two days later, on April 8 at 09:35 UTC (5:35 a.m. EDT) the MODIS instrument that flies aboard NASA's Aqua satellite captured a visible light image of Tropical Cyclone Joalane that showed the storm maintained an eye that it developed the previous day. Bands of thunderstorms wrapped into the center of circulation. The largest, thickest band of thunderstorms appeared on the eastern side of the center.

At 1500 UTC (11 a.m. EDT) on April 8, 2015, Tropical Cyclone Joalane's maximum sustained winds were near 90 knots (103.5 mph/166.7 kph). It was centered near 15.6 south and 64.9 east, about 624 nautical miles (718.1 miles/1,156 km) east-northeast of St. Denis.

Joalane is moving to the southeast at 9 knots (10.3 mph/16.6 kph). At that time, there were no tropical cyclone warnings in effect for Rodrigues Island.

Tropical Cyclone Joalane has intensified and the Joint Typhoon Warning Center forecast a southeastern track through the Southern Indian Ocean. Joalane is expected to weaken to a tropical storm by April 13.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
