The Eastern Pacific has generated the twelfth tropical depression of the hurricane season, and satellite imagery showed that it dwarfs nearby Tropical Storm Karina.
Tropical cyclones are usually a couple of hundred miles in diameter. The average size of a tropical cyclone is around 304 nautical miles (350 miles/600 km) in diameter.
The National Hurricane Center noted on August 18 at 11 a.m. EDT that Tropical Depression 12-E was at least 800 nautical miles (920.6 miles/1,482 km) in diameter! By comparison, Tropical Storm Karina is a couple of hundred miles in diameter.
At 11 a.m. EDT on August 18, tropical-storm-force winds extended outward up to 80 miles (130 km) from Karina's center.
NASA/NOAA's GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Maryland generates visible and infrared satellite imagery of the Eastern and Central Pacific Oceans from NOAA's GOES-West and GOES-East satellites.
On August 18, at 11 a.m. EDT (1500 UTC) the center of Tropical Depression Twelve-e was located near latitude 16.7 north and longitude 117.7 west, that's about 665 miles (1,065 km) southwest of the southern tip of Baja California.
Maximum sustained winds are near 35 mph (55 kph), and the depression is expected to become a tropical storm late on August 18.
The depression is moving toward the west-northwest near 8 mph (13 kph) and the National Hurricane Center expects a turn toward the northwest followed by a turn north on August 19.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
