NASA sees Tropical Storm Alenga intensifying

08.12.2011
NASA's TRMM satellite passed over Tropical Storm Alenga and noticed that the rainfall has intensified in the storm in the last two days indicating that it continues strengthening.

The Tropical Rainfall Measuring Mission satellite called TRMM again passed over intensifying tropical storm Alenga in the South Indian Ocean on December 5, 2011 at 2103 UTC (6:03 p.m. EST). As expected, Alenga had become better organized with TRMM's Precipitation Radar (PR) seeing scattered bands of heavy rainfall spiraling into the center of the storm.

A 3-D image using TRMM PR was created at NASA's Goddard Space Flight Center in Greenbelt, Md. Very powerful storms were seen in the 3-D image. Some of those powerful thunderstorms reached heights of about 16 km (~9.9 miles). TRMM PR also found a reflectivity value of 53.67 dBZ which is an another indication that very heavy rainfall was occurring in those storms.

On Dec. 7, 2011 at 0600 UTC (1 a.m. EST), Tropical Storm Alenga's maximum sustained winds were up to 55 knots (63 mph/102 kmh)from 45 knots (52 mph/83 kmh)a day ago. Alenga was still safely at sea and far from land. The center of Alenga was located about 415 nautical miles west-southwest of the Cocos Islands near 14.5 South latitude and 90.2 East longitude. Alenga was moving to the east-southeast near 15 knots (17 mph/28 kmh).

On Dec. 7, satellite imagery showed improved banding of thunderstorms around the low-level center of the cyclone. The strongest bands of thunderstorms were on the northern side of Alenga's center.

Tropical Storm Alenga is forecast to keep strengthening because of warm sea surface temperatures and low wind shear. Alenga may reach hurricane-force over the next day or two before encountering strong westerly wind shear and weakening.

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

Im Focus: Researchers develop method to transfer entire 2D circuits to any smooth surface

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.

Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...

Im Focus: Three components on one chip

Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.

Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
