Polar vortex forecasts gain months of lead time with new climate-based method

Florida State University researchers have discovered how to accurately predict winter weather forecasts months in advance, affording sectors such as agriculture, water management, energy use and public health a longer lead time to prepare for inclement conditions. The research, published in Journal of Geophysical Research: Atmospheres, shows a method for forecasting how the stratospheric polar vortex, or SPV, will behave from winter through summer, before winter even starts.
