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.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
