The Atmospheric Infrared Sounder (AIRS) instrument that flies on NASA's Aqua satellite gives scientists and meteorologists clues about how a tropical cyclone is behaving by providing critical temperature data.
NASA\'s Aqua satellite captured an infrared image of Tropical Depression 12 early on Sept. 12 when it was just east-southeast of the Cape Verde Islands. At that time it showed strong convection and powerful thunderstorms around its center (purple). By 11 p.m. EDT that day it became Tropical Storm Julia. Warm sea surface temperatures of 80F or higher (orange) surround Julia.

The TRMM satellite captured heavy rainfall (red) around Julia\'s center on Sept. 12 at 1822 UTC (2:22 p.m. EDT) about 9 hours before she reached tropical storm status. Rain in the red areas was falling at more than 2 inches per hour.

When Aqua flew over Tropical Depression 12 early on Sept. 12 the concentration of strong convection (rapidly rising air that forms thunderstorms that power a tropical cyclone) were large and surrounded the depression's center. Cloud top temperatures over a large area were as cold or colder than -63 degrees Fahrenheit, and those thunderstorms were strong. The convection continued on Sept. 12 and the storm finally strengthened into Tropical Storm Julia.The Tropical Rainfall Measuring Mission (TRMM) satellite, which is operated jointly by NASA and the Japanese Space Agency, JAXA captured a very good daytime look at Julia when she was tropical depression 12 on September 12 at 1822 UTC (2:22p.m. EDT). TRMM showed that TD12 was starting to get organized and had moderate to very heavy rainfall converging into the center of the future storm's circulation. Julia is another in a series of 2010 tropical cyclones forming near the Cape Verde Islands off the African Coast.
She was "born" on Sept. 12 at around 11 a.m. EDT near 12.7 North and 21.4 West. Since then, she's moved west to 14.5 North and 25.6 West, which is about 85 miles west-southwest of the southernmost Cape Verde Islands. Her maximum sustained winds are near 40 mph, and is expected to strengthen in the next couple of days, possibly reaching hurricane status. Julia is moving west-northwest near 14 mph and had a minimum central pressure of 1004 millibars.
Julia is expected to continue moving west-northwest, then turn northwest and slow down tomorrow.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
