NASA's TRMM Satellite Sees Cyclone Jasmine in 3-D

10.02.2012
Data from NASA's TRMM satellite was used to create a 3-Dimensional look at Cyclone Jasmine, currently moving through the South Pacific Ocean.

The Tropical Rainfall Measuring Mission (TRMM) satellite is managed by both NASA and the Japanese Space Agency. Using TRMM data, 3-D images of Cyclone Jasmine were created at NASA's Goddard Space Flight Center in Greenbelt, Md.

The TRMM satellite traveled directly above tropical cyclone Jasmine in the South Pacific Ocean on February 8, 2012 at 2156 UTC (4:56 p.m. EST). Jasmine was classified as a powerful category 4 on the Saffir Simpson Scale with wind speeds of 115 kts (~132 mph) at its peak intensity but had started to weaken at the time of this pass.

A 3-D image was created using data from TRMM's Precipitation Radar (PR). The 3-D cutaway image revealed the funnel shaped surface of Jasmine's eye. TRMM PR data also showed that heights of Jasmine's tallest storms then reached to heights of about 11.5 km (~7.1 miles).

Rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that intense thunderstorms in bands wrapping around Jasmine's large circular eye were dropping rain at a rate of over 50mm/hr (~2 inches). This was a daytime pass so the rainfall analysis was overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) instrument.

Infrared imagery from instruments like the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite revealed that cloud top temperatures in Jasmine have been warming since early morning on February 9, 2012. That's an indication that the system is losing strength and the cloud tops are falling.

Jasmine is a small cyclone, only about 90 nautical miles (103.6 miles/166.7 km)in diameter, and the eye is about 20 nautical miles (23.2 miles/37 km) wide.

On February 9, 2012 at 0900 UTC, Jasmine's maximum sustained winds were near 105 knots (120.8 mph/194.5 kph). Jasmine was about 275 nautical miles (316.5 miles/509.3 km) east-southeast of Noumea, New Caledonia near 28.8 South and 171.4 East. Jasmine is moving to the south-southeast around 10 knots (11.5 mph/18.5 kph).

Jasmine is expected to move over cooler waters and encounter drier air, two factors that will further weaken the storm.

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...
