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.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
