Polar Vortex 2019: Why Forecasts Are So Accurate Now - The Atlantic
“A modern five-day forecast is as accurate as a one-day forecast was in 1980,” says a new paper, published last week in the journal Science. “Useful forecasts now reach nine to 10 days into the future.”

Polar Vortex 2019: Why Forecasts Are So Accurate Now - The Atlantic
"Understanding months-long events like El Niño, for instance, has allowed meteorologists to go beyond the seven-day forecast. Alley, the Penn State professor, says that he is awed by the new models. Well-studied features of Earth’s climate—like the temperate Gulf Stream in the Atlantic Ocean—emerge in computer models, even though developers have written code that only mimics basic physics. “You translate Newtonian physics into a sphere and get Coriolis [force],” he says. “There’s no line in the code that says, Please make a Gulf Stream. But it is the physics of the Earth, so when you spin it up, the Gulf Stream appears because it has to.”"

A Non‐Gaussian Spatio‐Temporal Model for Daily Wind Speeds Based on a Multi‐Variate Skew‐t Distribution - Tagle - - Journal of Time Series Analysis - Wiley Online Library
"Facing increasing domestic energy consumption from population growth and industrialization, Saudi Arabia is aiming to reduce its reliance on fossil fuels and to broaden its energy mix by expanding investment in renewable energy sources, including wind energy. A preliminary task in the development of wind energy infrastructure is the assessment of wind energy potential, a key aspect of which is the characterization of its spatio‐temporal behavior. In this study we examine the impact of internal climate variability on seasonal wind power density fluctuations over Saudi Arabia using 30 simulations from the Large Ensemble Project (LENS) developed at the National Center for Atmospheric Research. Furthermore, a spatio‐temporal model for daily wind speed is proposed with neighbor‐based cross‐temporal dependence, and a multi‐variate skew‐t distribution to capture the spatial patterns of higher‐order moments. The model can be used to generate synthetic time series over the entire spatial domain that adequately reproduce the internal variability of the LENS dataset."
