The Geostationary Operational Environmental Satellites like GOES-13 are managed by NOAA. The NASA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. creates images and animations from the GOES satellite data. When GOES-13 provided an infrared image (because it was taken at night) today, Nov. 2 at 0845 UTC (4:45 a.m. EDT), Tropical Storm Tomas showed a little more organization in its clouds after battling wind shear yesterday.
The GOES-13 satellite captured a strengthening Tropical Storm Tomas this morning, Nov. 2 at 0845 UTC (4:45 a.m. EDT) in infrared imagery. Tomas appears as the rounded area of clouds (bottom right) about 310 miles due south of Port Au Prince, Haiti. In the larger image, the clouds over northwestern Louisiana (top left) are from a low and associated cold front stretching southwest to north-central Mexico.

Infrared satellite data also showed that convection (rapidly rising air that form the thunderstorms that make up a tropical cyclone) has increased or deepened in Tomas. This morning most of that convection and thunderstorm activity is occurring over the eastern and northeastern areas around the center of circulation.
The wind shear over the south-central Caribbean Sea has weakened which has allowed Tomas to gradually re-strengthen. The waters are also much warmer than the 80 degree threshold needed to maintain or strengthen a tropical cyclone. Because of these improving conditions, the National Hurricane Center forecasts that Tomas will continue strengthening until Friday when an upper-level trough (elongated area of low pressure) will push Tomas north-northeastward toward the Windward Passage and parts of Hispaniola.
At 5 a.m. EDT, Tropical Storm Tomas had maximum sustained winds near 50 mph (up from 45 mph on Nov. 1). Tomas is moving west near 12 mph and has a minimum central pressure of 1003 millibars. The center of Tomas is located about 355 miles south of Port-au-Prince, Haiti near 13.5 North and 72.0 West. Tomas is being steered along the southern and southwestern edge of ridge (an elongated area) of high pressure which is moving Tomas west.
To visualize Tomas' movement, picture a penny on a table and move your finger from the bottom of the penny to the left. The penny is the area of high pressure, and your finger would be Tomas. High pressure areas act as a wall that tropical cyclones can't penetrate, so they move around the edges.
Tomas is forecast to become a hurricane on Thursday, Nov. 4 and turn to the northeast, threatening Haiti. Currently there are no watches and warnings in effect, but that's likely to change later this week.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
