Climate ‘memory’ may aid long range forecasts

26.03.2003


Researchers at Harper Adams University College, Shropshire, believe a ‘memory’ in the climate system could be tapped to improve long-range weather forecasts.



In the April edition of ‘Weather,’ the journal of the Royal Meteorological Society, an article co-written by Dr Peter Kettlewell will show how summer rainfall levels in the UK are affected by ‘remembered’ changes in winter air pressure over the North Atlantic ocean. The article is based upon the work of a team headed by Dr Kettlewell, a senior researcher at Harper Adams, and co-author Dr David Stephenson, Head of the Climate Analysis Group at the University of Reading. Sponsored by the Home Grown Cereals Authority (HGCA), this work has previously shown that the quality of UK wheat grain is directly affected by the climate changes over the North Atlantic Ocean. Large-scale alterations in air pressure between the northern and southern regions of the North Atlantic, known as the North Atlantic Oscillation or NAO, take place during the winter and affect the quality of wheat grain that is harvested during the following summer.

Continuing work on the phenomenon has now shown that the winter NAO affects wheat quality by influencing summer rainfall levels. High NAO levels in winter tend to be followed by a dry summer in England and Wales, while wet summers tend to be preceded by low NAO winters. This relationship holds true for much of northwestern Europe and southern Scandinavia and has allowed Dr Kettlewell to build up a two category forecasting system, of above or below average summer rainfall.

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

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.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

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.

Im Focus: Complex hardmetal tools out of the 3D printer

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...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

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...

Im Focus: New laser joining technologies at ‘K 2016’ trade fair

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
