A visible image of Tropical Storm Toraji was captured on Sept. 3 at 02:10 UTC/Sept. 2 at 10:10 p.m. is it continued moving north past eastern China and approached southern Japan.
The image was taken by the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite. The image showed strong thunderstorms wrapped around the center of the tropical storm. Bands of thunderstorms wrapping into the center from the north extended over Kyushu. Kyushu is the third largest island of Japan and is farthest southwest of Japan's four main islands.
At 1500 UTC/11 a.m. EDT on Monday, Sept. 2, Toraji had maximum sustained winds near 35 knots/40 mph/64 kph, so it was a minimal tropical storm. It was located about 100 miles northwest of Kadena Air Base, Okinawa, near 27.7 north and 126.5 west. Toraji was generating 13-foot/3.9-meter-high seas. That day, infrared satellite data from the MODIS instrument aboard NASA's Aqua satellite showed strong bands of thunderstorms wrapping around the southeastern and eastern quadrant of the storm, and spinning into the low-level center of circulation. Aqua passed over Toraji on Sept. 2 at 1328 UTC/9:28 a.m. EDT.
By Monday, Sept. 3 at 1500 UTC/11 a.m. EDT, Toraji's maximum sustained winds increased to 50 knots/57.5 mph/92.6 kph. The strongest winds are in the northeastern quadrant of the storm. Toraji moved closed to Kyushu and was centered near 30.5 north and 129.3 east, about 172 nautical miles/198 miles/318 km south-southwest of Sasebo, Japan. Toraji is moving to the northeast at 9 knots/10.3 mph/16.6 kph.
Wind shear has increased from the southwest today, Sept. 3. A deep layered mid-latitude trough (elongated area of low pressure) located over the Yellow Sea has created strong vertical wind shear. Winds are blowing from the southwest at up to 30 knots/34.5 mph/55.5 kph.
Toraji is now expected to make landfall in Kyushu and move back over open waters in the Sea of Japan where it is expected to parallel the western coast of Japan. It is expected to begin interacting with mid-level westerly winds and the Baroclinic Zone and become extra-tropical later today.
According to NOAA, the Baroclinic Zone is a region in which a temperature gradient exists on a constant pressure surface. Baroclinic zones are favored areas for strengthening and weakening systems; barotropic systems, on the other hand, do not exhibit significant changes in intensity. Also, wind shear is characteristic of a baroclinic zone, and wind shear can tear tropical cyclones apart.
Between the increased wind shear from the southwest and the interaction with the land (Kyushu), Tropical Storm Toraji is not expected to intensify before making landfall.

A unique solar panel design made with a new ceramic material points the way to potentially providing sustainable power cheaper, more efficiently, and requiring less manufacturing time.
It also reaches a four-decade-old goal of discovering a bulk photovoltaic material that can harness energy from visible and infrared light, not just ultraviolet light.
Scaling up this new design from its tablet-size prototype to a full-size solar panel would be a large step toward making solar power affordable compared with ...
Atlantische Flohkrebse pflanzen sich jetzt auch in arktischen Gewässern fort
Biologen des Alfred-Wegener-Institutes, Helmholtz-Zentrum für Polar- und Meeresforschung (AWI), haben zum ersten Mal nachgewiesen, dass sich in den arktischen Gewässern westlich Spitzbergens auch Flohkrebse aus dem wärmeren Atlantik fortpflanzen.
Diese überraschende Entdeckung deute auf einen möglichen Wandel der arktischen Zooplankton-Gemeinschaft hin, berichten die Wissenschaftler und Wissenschaftlerinnen in der Fachzeitschrift Marine Ecology ...
The molecular architecture of three key proteins and their complexes reveals how plants fine-tune their immune response to pathogens
Plants rarely get sick in their natural environment. When the threat of infection arises, a quick decision is made about the necessary countermeasures. The course is set by a protein which forms complexes with its partner proteins for this purpose.

Researchers studying speciation of butterfly orchids on the Azores have been startled to discover that the answer to a long-debated question "Do the islands support one species or two species?" is actually "three species".
Hochstetter's Butterfly-orchid, newly recognized following application of a battery of scientific techniques and reveling in a complex taxonomic history worthy of Sherlock Holmes, is arguably Europe's rarest orchid species. Under threat in its mountain-top retreat, the orchid urgently requires conservation recognition.
A lavishly illustrated publication, titled "Systematic revision of Platanthera in ...
Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon's largest impact crater.
Data from the Moon Mineralogy Mapper that flew aboard India's Chandrayaan-1 lunar orbiter shows a diverse mineralogy in the subsurface of the giant South Pole Aitken basin.
The differing mineral signatures could be reflective of the minerals dredged up at the time of the giant impact 4 billion years ago, ...
