NASA sees heavy rain around Super-Typhoon Haiyan's eye

07.11.2013
Super Typhoon Haiyan continues moving toward the Philippines, and when NASA's TRMM satellite passed overhead, it was very close to the island of Palau and packing heavy rainfall. Haiyan is now equivalent to a Category 5 Hurricane.

The forecasters at the Joint Typhoon Warning Center or JTWC accurately predicted that Typhoon Haiyan would become a powerful category five typhoon with sustained winds estimated to be over 135 knots/~155 mph.


Data from TRMM's TMI and PR instruments on Nov. 6 at 1026 UTC revealed that rain was falling at a rate of over 100mm/~3.9 inches per hour (purple) around Haiyan's eye.

On Nov. 6, a typhoon Warning remained in effect for Kayangel and Koror in the Republic of Palau and Ngulu in Yap State and a tropical storm warning was in effect for Yap Island in Yap State.

Super typhoon Haiyan was located just northeast of Palau when the TRMM or Tropical Rainfall Measuring Mission satellite flew above on November 6, 2013 at 1026 UTC/5:26 a.m. EST. At NASA's Goddard Space Flight Center in Greenbelt, Md. a rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments was overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS). The data revealed that rain was falling at a rate of over 100mm/~3.9 inches per hour around Haiyan's eye.

Satellite data also showed a persistent ring of deep convection around the small eye. Haiyan's eye appeared to be about 8 nautical miles in diameter. The TRMM satellite's microwave data showed an intense convective core (thunderstorms building around the eye) and improved convective banding of thunderstorms in all quadrants of the super-typhoon.

At 1500 UTC/10 a.m. EDT, Super Typhoon Haiyan had maximum sustained winds near 140 knots/161 mph/259 kph. That makes Haiyan equivalent to a Category 5 Hurricane on the Saffir-Simpson hurricane scale.

The U.S. National Hurricane Center website indicates that a Category 5 hurricane/typhoon would cause catastrophic damage: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

Hiayan's center was located near 8.1 north and 135.4 east, about 113 nautical miles/130 miles/209.3 km east-northeast of Koror, Palau. It is moving to the west at 18 knots/20.7 mph/33.4 kph and generating 43-foot/13.1-meter-high seas.

Super typhoon is expected to make landfall over the central Philippines just slightly on Nov. 8 and will slightly weaken as it tracks across the islands before emerging in the South China Sea.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
