Tropical Depression 21W Forms, Philippines Under Warnings

27.11.2014

The Tropical Rainfall Measuring Mission or TRMM satellite provided rainfall data as Tropical Depression 21W was making landfall in the southern Philippines on Nov. 26.

TRMM revealed areas of heavy rainfall in fragmented bands east of the center of circulation, where rain was falling at more than 1 inch (25 mm) per hour.

TRMM rainfall data was overlaid on infrared data from the Japan Meteorological Agency's MTSAT-1 satellite that showed Tropical Depression 21W's (TD21W) clouds extended from western Mindanao, east into the Philippine Sea.

On Nov. 26, there were a number of warnings in effect for the Philippines. Public storm warning signal #1 was in effect for the province of Luzon that includes: Palawan and the Calamian Group of Islands. In Visayas: Southern Leyte, Bohol, Southern Cebu Including Cebu City, Negros Oriental, Southern Negros Occidental and Siquijor. In the province of Mindanao:

Surigao del Norte including Siargao Island, Surigao del Sur, Agusan del Norte & Sur, Dinagat Province, Camiguin, Misamis Oriental & Occidental, Bukidnon and Zamboanga del Norte.

At 1500 UTC (10 a.m. EST), TD21W was centered near 8.7 north longitude and 125.4 east latitude. That's about 468 nautical miles (538.6 miles/866.7 kph) southeast of Manila, Philippines. Maximum sustained winds were near 30 knots (34.5 mph/55.5 kph). TD21W is moving to the west at 9 knots (10.3 mph/16.6 kph).

TD 21W is forecast to continue tracking westward along the southern edge of a sub-tropical ridge of high pressure which is located to the north of the depression and oriented east-west. The Joint Typhoon Warning Center forecasts TD21W to move over northern Mindanao late on Nov. 26 and weaken. By Nov. 27, TD21W is expected to emerge into the Sulu Sea where it is expected to strengthen.

Im Focus: Fraunhofer IDMT demonstrates its method for acoustic quality inspection at »Sensor+Test 2019« in Nürnberg

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.

Reducing machine downtime, manufacturing defects, and excessive scrap

Im Focus: Successfully Tested in Praxis: Bidirectional Sensor Technology Optimizes Laser Material Deposition

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.

Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
