Abstract : It is almost impossible to define with uniform precision the entire spectrum of atmospheric movements when conducting a numerical forecast. Therefore, a model being used for long-range forecasting must describe in detail the evolution of the largest-scale components of atmospheric circulation approximately taking into consideration the effect of smaller-scale disturbances. The article gives the results of calculations conducted on the basis of a spectral model while using initial data as the starting information. It examines the question of the effect of initial information errors on the quality of the forecast.
