The Tropical Rainfall Measuring Mission (TRMM) satellite provided good coverage of Sanba as it passed over Typhoon Sanba on Sept. 16, 2012 at 0349 UTC, after Sanba had passed over Okinawa, Japan. Sanba was moving northward over the East China Sea toward South Korea and its circulation was affecting western Japan.
Powerful thunderstorms around Sanba's eye wall on Sept. 16, 2012, 0349 UTC were revealed to be about 12km (~7.5 miles) high. However, the tallest thunderstorm towers, reaching to 14km (~8.7 miles), were found by TRMM PR in an intense rain band shown circulating south of Sanba's center as it passed over Okinawa.

Later, the TRMM satellite again passed over Sanba on Sept. 16, 2012 at 2339 UTC (7:39 p.m. EDT). Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that Sanba was concentrating rain at a rate of over 90 mm (~3.5 inches) per hour in an area near South Korea's southern coast. TRMM saw that rain bands from Sanba were still producing scattered heavy showers as far away as the Japanese island of Shikoku.
TRMM Precipitation Radar (PR) data collected with the September 16, 2012 0349 UTC pass were used to create a 3-D cut-away view of the storm, looking from the northwest. At that time, the typhoon had weakened slightly but was still a strong category two typhoon with wind speeds of about 95 knots (~109 mph). The 3-D image showed powerful thunderstorms around Sanba's eye wall were about 12km (~7.5 miles) high. However, the tallest thunderstorm towers, reaching to 14km (~8.7 miles), were found by TRMM PR in an intense rain band shown circulating south of Sanba center.
On Sept. 17, Typhoon Sanba made landfall in the south Gyeongsang Province, located on the southern coast of South Korea.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...
