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."

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
