GOES-13 Satellite sees Lisa a tropical storm...for now

27.09.2010
The GOES-13 satellite has been keeping an eye on Tropical Storm Lisa and watched her birth, graduation to depression then tropical storm and back to depression. Now, Lisa has grown back to tropical storm status, but it may be short-lived.

At 11 a.m. EDT on Friday, Sept. 24, Tropical Storm Lisa had maximum sustained winds near 50 mph and she may strengthen and weaken over the weekend, but by Sunday colder waters will zap her energy source and she is forecast to be a depression.

Meanwhile, on Sept. 24, she was still frolicking in the eastern Atlantic, about 320 miles northwest of the Cape Verde Islands, near 18.9 North latitude and 27.8 West longitude. Lisa was moving north at 7 mph and is expected to turn north-northwest on Sept. 25. Estimated minimum central pressure is 1000 millibars.

The GOES-13 satellite captured a visible image of Tropical Storm Lisa at 16 45 UTC (12:45 p.m. EDT) on Sept. 24. The GOES visible imagery showed that Lisa now has a well-organized center of circulation, which corresponds with infrared and microwave satellite imagery that showed convection has wrapped around three-fourths of the center of circulation.

The infrared data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite today showed that Lisa's thunderstorm cloud tops, north of the center of circulation had cooled down to a frosty -80 Celsius (-112 Fahrenheit), one factor that confirms her re-strengthening. The colder the cloud top temperatures, the higher the thunderstorms, and the more powerful they are. When cloud top temperatures cool, it indicates a strengthening storm. When they warm, a storm is weakening.

Over the weekend, Lisa will move into colder waters and the westerly wind shear will increase ahead of an elongated are of low pressure. The wind shear is forecast to be moderate to strong. So strong that they're expected to "decouple" or separate the low-level circulation from the upper-level circulation in the storm causing it to weaken significantly.

Lisa is expected to become a remnant low pressure system by early next week in the eastern Atlantic.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
