NASA sees Tropical Storm Washi's rainfall intensify over larger area

19.12.2011
NASA's TRMM satellite noticed that as Tropical Storm Washi approached the Philippines' island of Mindanao heavy rainfall had become more widespread than the previous day. NASA's Terra satellite captured Washi making landfall early today.

Early on Dec. 15 when NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed over Tropical Storm Washi, (known as Sendong in the Philippines) there was one area to the southwest of the center that had heavy rainfall. When TRMM passed over Washi later on Dec. 15 at 1515 UTC (10:15 a.m. EST), heavy rainfall was more widespread throughout the entire storm. TRMM saw areas of heavy rain, falling at 2 inches (50 mm) per hour, in the east, north and western quadrants of the storm.

That rainfall analysis was created at NASA's Goddard Space Flight Center in Greenbelt, Md. using the TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data overlaid on an enhanced infrared image from the satellite's Visible and InfraRed Scanner (VIRS). The rainfall analysis showed that Washi was much better organized and bands of thunderstorms spiraling into the center of the storm.

TRMM PR data was also used to create a 3-D image from the same satellite overpass and showed numerous heavy thunderstorms were located throughout the tropical cyclone. The tallest thunderstorms reached heights of over 15 km (~9.3 miles) and were located in the feeder bands converging into northwest side of the storm.

On Dec. 16 at 01:45 UTC, NASA's Terra satellite flew over Tropical Storm Washi and captured a visible image of the storm using the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. MODIS showed the western half of Washi was already over Mindanao in the southern Philippines. Mindanao is the second largest and easternmost island of the Philippines.

Warnings in effect in the Philippines for Dec. 16 include: Public storm warning signal #2 for Mindanao: Misamis Oriental & Occidental, Camaguin Island, Bukidnon, Lanao del Norte & Sur and Zamboanga Provinces. Public storm warning signal #1 is in effect for Mindanao: Bohol, Siquijor, Southern Cebu, Negros Oriental and Southern Negros Occidental; and for Visayas: Surigao Del Norte, Agusan del Norte & Sur, Davao del Norte, Compostela Valley, North Cotabato and Maguindanao; and in Luzon: Palawan.

At 1500 UTC (10 a.m. EST) on Dec. 16, Tropical Storm Washi's maximum sustained winds were near 50 knots (57 mph/92 kmh). Those tropical storm-force winds extend out 50 miles (80 km) from the center making the storm over 100 miles in diameter.

Washi was about 230 miles (370 km) east-northeast of Zamboanga, in Minandao Philippines near 8.4 North and 125.5 East. Washi was moving to the west-northwest at 13 knots (15 mph/24 kmh) but slowing down as it interacts with land. As Washi slowed, the Joint Typhoon Warning Center (JWTC)noted that convection (rising air that forms thunderstorms that make up the tropical storm) and thunderstorms spread to all quadrants of the storm. The strongest thunderstorms appeared over the southwestern quadrant this morning.

Washi was making landfall over Mindanao on Dec. 15 at 1500 UTC and will continue moving westward. The JTWC expects Washi to re-intensify over the Sulu Sea and make a final landfall this weekend in Vietnam.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
