As Tropical Cyclone Marcia was nearing the Queensland coast, the Tropical Rainfall Measuring Mission satellite known as TRMM measured its rainfall from space.
Tropical Cyclone Marcia made landfall along Queensland coast between Yeppoon and St. Lawrence around 2200 UTC on Feb. 19 (5 p.m. EST U.S./Feb. 20 at 8 a.m. local time Brisbane).
The TRMM satellite exhausted its station keeping fuel in July 2014 and has been drifting downward. On Feb. 19, NASA and the Japan Aerospace Exploration Agency's TRMM satellite had an excellent view of Marcia. About six minutes after seeing Lam land falling in the Northern Territory, TRMM flew directly above category five cyclone Marcia, located off Australia's northeastern coast. TRMM's Precipitation Radar (PR) found that some very intense storms in the northwestern side of Marcia's eye wall were dropping rain at the extreme rate of 225 mm (8.8 inches) per hour.
At NASA's Goddard Space Flight Center in Greenbelt, Maryland a 3-D View of Marcia was made from TRMM's Precipitation Radar (PR) data. The 3-D image showed that some thunderstorm tops in the small but powerful tropical cyclone were reaching heights of over 15.2 km (9.4 miles).
Marcia made landfall late on Feb. 19 (U.S. Eastern Time) and is weakening rapidly. Forecasters expect that its track over land will continue weakening the system. However, Marcia's remnants will reemerge over the southern Coral Sea, but it is not expected to re-generate.
The Joint Typhoon Warning Center issued their warning for Tropical cyclone Marcia at 0900 UTC (4 a.m. EST) on Feb. 20. At that time, Marcia was centered near 23.8 south and 1506. East, about 262 nautical miles north-northwest of Brisbane, Australia. Marcia's maximum sustained winds dropped to 75 knots (86 mph/138.9 kph). Marcia weakened quickly afterward and six hours later was a remnant low pressure area.
At 1 a.m. local Brisbane time on Feb. 21 (10 a.m. EST, Feb. 20), Marcia's winds had dropped to 55 kph (34 mph) over land, making it a remnant low pressure area. There were not tropical cyclone warnings or watches in effect, but heavy rain was main concern.
The ABM noted " Heavy rainfall is occurring about coastal and adjacent inland areas between Bundaberg and Gympie, and this area of rainfall is expected to translate southwards with the system tonight and Saturday morning. A Flood Watch is current for the area." For updates on the storm, visit ABM's website: http://www.

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
