NASA-NOAA's Suomi NPP satellite passed over Tropical Storm Henri on September 11 and saw that almost all of the clouds and showers associated with the storm were on the northeastern side of the storm.
At 0544 UTC (1:44 a.m. EDT) Infrared data from the Visible Infrared Imaging Radiometer Suite or VIIRS instrument that flies aboard Suomi NPP showed cloud top temperatures in the northeastern quadrant of Henri were as cold as -63F/-53C, indicating strong storms reaching high into the troposphere. Clouds around the rest of the tropical storm were warmer (and much lower in the atmosphere) and devoid of rainfall.
Southeasterly wind shear is responsible for pushing the clouds and showers to the northeast of Henri's center. In addition, there's dry air around the system which is inhibiting the development of thunderstorms in the other areas of the storm.
National Hurricane Center forecaster Kimberlain noted on September 11 at 5 a.m. EDT, "While nearly all of the cyclone's deep convection is still located well to the northeast of the center, a relatively new convective burst over this area has grown in coverage and cloud tops have cooled."
At 5 a.m. EDT (0900 UTC), the center of Tropical Storm Henri was located near latitude 36.2 North, longitude 60.3 West. That's about 370 miles (600 km) northeast of Bermuda and about 815 miles (1,310 km) south-southwest of Cape Race Newfoundland, Canada.
Maximum sustained winds were near 40 mph (65 kph) and little change in strength is forecast during the next two days. However, Henri is expected to become a post-tropical storm by September 13.
Henri is moving toward the north near 16 mph (26 kph) and the National Hurricane Center forecast calls for a turn toward the north-northeast then to the northeast by Sunday, September 13.
The NHC noted that the southerly vertical shear appears to be diminishing over the cyclone so some additional intensification could occur later on September 11.
However, forecaster Kimberlain noted "the continued presence of dry air in the near-storm environment and Henri's disorganized appearance suggest that any intensification should be negligible. After the cyclone crosses the northern wall of the Gulf Stream in less than 18 hours, substantially lower sea surface temperatures and increasingly stable air should induce weakening soon after that."

New findings on the largest natural sulfur source in the atmosphere

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.
With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.
Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...
