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: Regensburg physicists watch electron transfer in a single molecule

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...

Im Focus: Famous “sandpile model” shown to move like a traveling sand dune

Researchers at IST Austria find new property of important physical model. Results published in PNAS

The so-called Abelian sandpile model has been studied by scientists for more than 30 years to better understand a physical phenomenon called self-organized...

Im Focus: Cryo-force spectroscopy reveals the mechanical properties of DNA components

Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.

DNA is not only a popular research topic because it contains the blueprint for life – it can also be used to produce tiny components for technical applications.
