When winter’s on the horizon, investors and energy traders know there’s no substitute for an accurate seasonal forecast and subseasonal updates.
AER was the only firm that correctly predicted the cold winter of 2010-2011. (See map below.) We're pleased to share verification of AER's forecast skill in prior years to qualified energy investors and fund managers; request forecast skill here.
AER clients were significantly better positioned to maximize their weather impacted investments, well ahead of the rest of the market.

The high skill of the Seasonal Forecast is based on over a decade of extensive atmospheric research.
Unlike other seasonal weather forecasts, the AER winter forecast uses a unique initialization scheme that analyzes snow cover in Siberia in addition to El Niño/Southern Oscillation (ENSO) and warming trends. AER has shown that Siberian snow cover can be use to predict the strength of the polar vortex, which is highly correlated with the frequency of Arctic outbreaks in the mid-latitudes of the Northern Hemisphere.
