NASA sees Tropical Storm Helen affecting southeastern India

22.11.2013
NASA's Aqua satellite captured visible and infrared imagery of slow-moving Tropical Storm Helen as it was spreading its western clouds over parts of southeastern India on November 21.

On Nov. 21 at 07:55 UTC/2:55 a.m. EDT the MODIS or Moderate Resolution Imaging Spectroradiometer instrument that flies aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Helen that showed clouds in the storm's western quadrant had already spread over eastern India.

Two minutes before the MODIS instrument captured the visible image of Helen's clouds, the infrared instrument aboard Aqua called the Atmospheric Infrared Sounder or AIRS instrument used infrared light to gather data from the storm. The infrared data showed that the strongest thunderstorms with the coldest cloud top temperatures were still off-shore.

The stretched around the center from northwest to southwest and wrapped around to the east. Only the bands of thunderstorms in the northern quadrant appeared to be fragmented, which could be a result of that area's interaction with land.

On Nov. 21 at 1500 UTC/10 a.m. EST, Tropical Cyclone Helen was located about 495 nautical miles/569.6 miles/ 916.7 km southwest of Calcutta, India, near 16.1 north and 83.0 east. Helen was moving a little faster than the previous day, now at 4 knots/4.6 mph/7.4 kph to the northwest. Helen's maximum sustained winds had increased slightly to 55 knots/63.2 mph/101.9 kph, and those tropical storm force winds extend out 65 nautical miles/74.8 miles/120.4 km from the center. Helen was also creating maximum wave heights of up to 20 feet/6.0 meters, and causing rough seas along the southwestern coast of India.

As a result of the strong waves and tropical-storm force winds, warnings are in effect for Andhra Pradesh that include: A storm surge of 1 to 1.5 meters/3.2 to 4.9 feet will occur at the time of landfall, Thatched roofs and huts will sustain damage and a call for fisheries to cease operations.

Helen is expected to weaken as it nears the coast as it moves into cooler waters and continues to battle moderate wind shear. Helen is expected to make landfall near Tenali early on November 22. After landfall, Helen should weaken as it moves west where it is expected to dissipate in a couple of days.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

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...
