NASA: Songda becomes a super typhoon

NASA's 3-D rotating satellite-view of Songda

As predicted, Typhoon Songda intensified and was a super typhoon with wind speeds estimated at over 130 knots ( ~145 mph) when NASA's TRMM satellite passed directly over head on May 26, 2011 at 0806 UTC (4:06 a.m. EDT).

Songda had a circular eye with extremely heavy rainfall, particularly in the southeast quadrant. The red areas represent heavy rainfall (falling at about 2 inches/50 mm per hour). The yellow and green areas are moderate rainfall, falling at a rate between .78 to 1.57 inches (20 to 40 mm) per hour. Credit: NASA/SSAI, Hal Pierce

The Tropical Rainfall Measuring Mission (TRMM) satellite captured the heavy rainfall rates within the super typhoon using TRMM's Visible and InfraRed Scanner (VIRS) instrument. The rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data showed that Songda had a circular eye with extremely heavy rainfall (as much as 2 inches/50 mm per hour) particularly in the southeast quadrant. TRMM's PR instrument data showed the concentric rain bands typical of powerful typhoons.

Warnings are in effect in the Philippines today. Public storm warning signal no 1 is in effect in the following provinces: Luzon: Catanduanes, Camarines Sur & Norte, Quirino, Albay, Aurora, Quezon Provinces, Polilio Island, Cagayan and Isabela.

At 1500 UTC (11 a.m. EDT) on May 26, Super Typhoon Songda (called Chedeng in the Philippines) had maximum sustained winds near 140 knots (161 mph/259 kmh). Typhoon-strength winds extend 45 miles out from the center, while tropical storm-force winds extend 155 miles from the center, making Songda over 300 miles wide.

Songda's center was 250 miles east-northeast of Manila, near 16.2 North and 125.1 East. It was moving northwest near 8 knots (9 mph/15 kmh). Songda is creating very rough and dangerous seas in Philippine Sea, with wave heights reaching 38 feet (11.5 meters).

Songda has intensified in favorable conditions as the forecasters at the Joint Typhoon Warning Center predicted. Songda may have reached its peak intensity and is forecast to start turning to the northeast and weaken because of increased wind shear.

Songda will then start to veer northeast and weaken due to deteriorating atmospheric conditions.

Taiwan has already posted Marine Warnings for May 27 and 28, forecasting wave heights to increase from 2 meters (~6.5 feet) to as much as 6 meters (~20 feet) on east-facing shorelines as Super Typhoon Sondga moves past (it will stay off-shore and track to the east of Taiwan). The current track from the Joint Typhoon Warning Center takes Songda over the island of Kadena on May 28, and then skirting the east coast of Japan as it continues on a northeasterly track over the weekend.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
