Abstract: Predictability times are estimated from 500 mb heights resolved for horizontal scales from 5 ? 106 to 8 ? 106 m. These scales are defined through eigenvector analysis of seven years of winter data over a portion of the ...

Abstract: Empirical orthogonal functions for the 500 mb height and 850 mb temperature fields over a limited domain are obtained. These functions are then used as predictors in a regression model to forecast the height field 24 h in ...
