Snow Advance Index: A New Tool for Predicting Winter’s Severity Researchers at AER have developed a new Snow Advance Index that could greatly improve the accuracy of winter seasonal forecasts. Based on research and testing, this index for the first time can accurately predict the severity of the upcoming winter. What makes this discovery so significant is that advances in seasonal forecasting have remained elusive, and for much of the United States seasonal forecasts are no more accurate today then they were decades ago.

Not only are greenhouse gases a major force that is driving global warming, but their impacts on temperature change is also now known to be greater than initially thought. On top of that, annual global temperatures are continuing to accelerate. We have determined that, based on the average of a set of complex atmospheric model projections, the temperature will increase in the United States in each of its regions throughout the first half of the twenty-first century in both winter and summer.
