Reconstruction of seasonal and semiannual precipitation totals over europe from atmospheric pressure over the North Atlantic

A statistical method of reconstruction of winter and semiannual precipitation totals at the network of weather stations in Europe is considered. The sea-level pressure field in the North Atlantic is used as a predictor for precipitation reconstruction. The stability of pressure field filtration is studied from empirical orthogonal functions (EOF) with the help of informative parameter of the pressure vector components. Results of numerical experiments are presented.
