When that strength wanes, the cloud tops drop and become less cold. That's because the higher you go in the troposphere, the colder it gets. NASA satellite infrared data has revealed that Tropical Storm Tony's cloud top temperatures are warming and the storm is weakening.
The AIRS instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical Storm Tony on Oct. 24 at 12:17 p.m. EDT that showed the strongest thunderstorms (purple) east of the center of circulation but cloud top temperatures are warming. Those thunderstorms are reaching high into the troposphere where cloud top temperatures are as cold as -63 Fahrenheit (-52 Celsius).

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical Storm Tony on Oct. 24 at 12:17 p.m. EDT that showed the strongest thunderstorms east of the center of circulation, but cloud top temperatures are warming. Those thunderstorms are reaching high into the troposphere where cloud top temperatures are as cold as -63 Fahrenheit (-52 Celsius). The cloud pattern in Tony is also becoming less organized.
On Oct. 25, 2012 at 5 a.m. EDT Tropical Storm Tony had maximum sustained winds near 45 mph (75 kph). Tony was moving to the east-northeast near 23 mph (37 kph) and this general motion is expected to continue during the next couple of days. Tony's center is far from land, about 835 miles (1,345 km) southwest of the Azores Islands near 30.4 North latitude and 38.4 West longitude. Tropical storm force winds extend outward up to 105 miles (165 km) from the center.
According to the National Hurricane Center discussion of Tony, "the southwesterly winds have not substantially separated the surface circulation from the convective canopy, although a combination of the shear and cooler waters has weakened the deep convection."
The National Hurricane Center expects Tony to start losing tropical characteristics today and dissipate over the weekend of Oct. 27 and 28.Text credit: Rob Gutro

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
