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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
