NASA-NOAA's Suomi NPP Satellite passed over Typhoon Rammasun early on July 14 and captured a visible image of the storm that showed large bands of thunderstorms wrapping into the center as it approached the central Philippines.
When NASA-NOAA's Suomi NPP satellite passed over Rammasun on July 14 at 04:20 UTC, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard took a visible image of the storm.
The VIIRS instrument showed large, thick bands of powerful thunderstorms wrapping into the low-level center of circulation. The largest band extended from the western to southern and around to the eastern quadrants of the storm before spiraling into the center. Powerful thunderstorms also surrounded the tightly wound eye.
VIIRS collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans. VIIRS flies aboard the Suomi NPP satellite, which is managed by both NASA and NOAA.
Forecasters at the Joint Typhoon Warning Center noted on July 14 that Rammasun had slowed in forward movement and continued to consolidate as convection (rising air that forms the thunderstorms that make up the tropical cyclone) has further strengthened and the storm has developed an irregular eye about 15 nautical miles wide.
Microwave satellite imagery showed the storm had strengthened as the eyewall (the powerful thunderstorms around the open eye) became more developed.
On July 14 at 1500 UTC (11 a.m. EDT), Typhoon Rammasun had maximum sustained winds near 75 knots. Rammasun was moving to the west-southwestward at 10 knots. It was centered near 12.7 north latitude and 127.6 east longitude, about 435 nautical miles southeast of Manila, and closing in on the central Visayas region of the Philippines.
Typhoon Rammasun is expected to make landfall in the eastern Visayas region of the Philippines around July 15 at 0000 UTC (July 14 at 8 p.m. EDT). On July 13, Public storm warning signal #1 was in force in the following Luzon provinces: Camarines Norte & Sur, Catanduanes, Albay and Sorsogon, and Public storm warning signal #1 was in force in the Visayas province of Northern Samar.
The Joint Typhoon Warning Center expects Rammasun to move across the central and northern Philippines in a northwesterly direction crossing near Manila around July 16 at 0000 UTC (July 15 at 8 p.m. EDT), then moving into the South China Sea for another landfall in mainland China, just north of Hainan Island late on July 18 as a typhoon.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
