Paul originated from a low pressure circulation embedded within the monsoon trough over the Arufura Sea between the northern coast of Australia and New Guinea. As the circulation drifted southward towards northern Australia it intensified slowly and only became a Category 1 cyclone on the evening of March 28, 2010 (local time) when the center was right over the northeast coast of the Northern Territory where it brought wind gusts of up to 110 kph (~70 mph, equivalent to a tropical storm on the US Saffir-Simpson scale).
Since its launch back in 1997, the Tropical Rainfall Measuring Mission satellite (better known as TRMM) has served as a valuable platform for monitoring tropical cyclones using its unique combination of active radar and passive microwave sensors. TRMM captured this first image of Paul at 9:08 UTC on March 28, 2010 (6:38 pm Australian CST) when the center was right over the northeast coast of the Northern Territory. The image shows the horizontal distribution of rain intensity inside the storm. Rain rates in the center of the swath are from the TRMM Precipitation Radar (PR), the only spaceborne precipitation radar of its kind, while those in the outer portion are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS).
Although Paul does not have a visible eye in the IR data, the center of the storm's circulation is clearly evident in the rain pattern over the coast. Paul's center of circulation is bordered by a band of moderate intensity rain to the northwest and surrounded by outer rainbands that spiral inwards to the south and east that have light to moderate rain. Embedded within the rainbands are occasional areas of heavy rain.
TRMM data was used to create a 3-D perspective of the storm from data from TRMM's Precipitation Radar instrument. The most prominent feature is a deep convective tower, which penetrates up to 9 miles (15 km) high. This corresponds with an area of intense rain in the northwestern eyewall evident in the TRMM's image of horizontal rainfall. These tall towers are associated with convective bursts and can be a sign of future strengthening as they indicate areas where heat, known as latent heat, is being released into the storm. This heating is what drives the storm's circulation. Despite Paul's proximity to land, it was able to intensify into a Category 2 cyclone (equivalent to a minimal Category 1 hurricane) by the following morning with wind gusts of up to 140 kph (~85 mph). Paul is hovering over land along the coast and is expected to weaken slowly over the next day or so; however, it could eventually re-emerge over the very warm waters of the Gulf of Carpentaria and re-intensify.
TRMM is a joint mission between NASA and the Japanese space agency JAXA.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
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...
