It’s incredibly difficult for scientists to accurately predict North American and European winters . The weather in these regions is driven by a phenomenon known as the North Atlantic Oscillation (NAO), and it’s often hard to pin down in advance. But thanks to a new supercomputer , researchers at the UK’s Met Office are now able to predict winter weather a full year ahead. https://www.youtube.com/watch?v=Z_G7NFMDsVY According to the Met Office, changes in air pressure in the North Atlantic Ocean are the primary driver of winter climate variability for Europe . The NAO can affect other areas of the world too; the Met Office is currently researching links between the NAO and China’s winter weather. The phenomenon influences temperatures and precipitation. Met Office researchers published a paper on their predictions this month in the journal Nature Geoscience . Not only would it be convenient to know what winter weather we’ll face, according to lead author Nick Dunstone, predicting the NAO could offer economic benefits. For example, the energy and transportation industries could operate more efficiently with a better picture of what the weather would be like in the coming winter.

The first phase of the supercomputer started operations over a year ago in August 2015. The UK government invested £97 million in the Met Office’s ” new high performance computing facility .” Back then the Met Office said the supercomputer would help them forecast the weather in greater detail, and it appears they’re delivering on that promise. So what will the weather be like this winter? According to paper co-author Adam Scaife, “Current signals suggest that the start to winter is likely to be cooler and drier than in 2015.” + Nature Geoscience + Met Office Images via Met Office Facebook

India is building a massive supercomputer that can predict future monsoons

Comments Off on India is building a massive supercomputer that can predict future monsoons

The Indian government is spending $60 million this year to build a supercomputer with just one purpose: predicting the weather. With the heavy rains of India’s monsoon season accounting for more than two-thirds of the country’s annual rainfall, on which agriculture is so dependent, it’s easy to understand why the meteorology office is pouring funds into the project. The system will use 3D modeling to better understand how seasonal rains will develop. The current forecasting system was first introduced under British rule of India , based on a statistical model. Historical patterns are combined with satellite data, radar readers, and information from observatories. As one might expect, while this system can reveal broad trends, it hasn’t led to especially accurate forecasts; in fact, the system failed to predict a major drought in 2009 .

That’s not an insignificant amount: agriculture accounts for about 18 percent of India’s GDP. The new supercomputer is expected to be up and running by next year, and will be able to work 10 times faster than the current system. Via The Verge Images via  Jakub Michankow and  Rajarshi MITRA

Comments Off on IBM and DARPA’s Ultra-High-Speed Digital Data Link Sets Energy Efficiency Record

The supercomputers of the future will be capable of amazing feats such as modeling global climate scenarios , running molecular-level simulations of cells, and designing nanostructures. In order to for these “exascale computers” to operate, they will need to be able to run an enormous amount of data quickly while keeping power consumption under control. Scientists at IBM in conjunction with DARPA have created an ultra-high-speed prototype optical link that sets a new energy efficiency record. The researchers are set to describe their invention at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) being held in Anaheim, CA from March 17-21.
