An infrared image from NOAA's GOES-West satellite showed what appeared to be a ghostly ring of clouds and no convection in former Hurricane Cristina on Monday, June 16 as the system weakened to a remnant low pressure area.
Convection is rising air that forms the thunderstorms that make up a tropical cyclone and when there is none, there are no thunderstorms to keep it going. That's exactly what happened to Cristina in the Eastern Pacific Ocean on Sunday, June 15.
At 11 a.m. EDT (8 a.m. PDT) on Sunday, June 15, Cristina had weakened to a tropical depression near latitude 20.1 north and longitude 113.3 west, about 290 miles (470 km) southwest of the southern tip of Baja California At that time the depression was moving toward the west-northwest near 6 mph (9 kph) and Cristina's maximum sustained winds had decreased to near 35 mph (55 kph).
Forecaster Brennan at the National Hurricane Center (NHC) noted that "Cristina continues to lack any deep convection, which is not surprising given the hostile environment of strong shear, cool waters and dry air."
That hostile environment took its toll on Cristina early on June 16 when the NHC declared Cristina a remnant low pressure area. At 09:07 UTC (5:07 a.m. EDT), the post-tropical remnant low pressure area formerly known as Cristina was centered near 21 north latitude and 115 west longitude.
The remnant low had maximum sustained winds near 20 to 25 knots (23 to ~29 mph/37 to ~46 kph) and was generating seas to 8 feet (2.4 meters). As Cristina's remnants continue to dissipate, NHC forecasters expect wave heights to decrease.

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...

The trend-forward world of display technology relies on innovative materials and novel approaches to steadily advance the visual experience, for example through higher pixel densities, better contrast, larger formats or user-friendler design. Fraunhofer ISC’s newly developed materials for optics and electronics now broaden the application potential of next generation displays. Learn about lower cost-effective wet-chemical printing procedures and the new materials at the Fraunhofer ISC booth # 1021 in North Hall D during the SID International Symposium on Information Display held from 22 to 27 May 2016 at San Francisco’s Moscone Center.
Staphylococcus aureus usually is a formidable bacterial pathogen. Sometimes, however, weakened forms are found in the blood of patients. Researchers of the University of Würzburg have now identified one mutation responsible for that phenomenon.
Staphylococcus aureus is a bacterium that is frequently found on the human skin and in the nose where it usually behaves inconspicuously. However, once inside...
