Description: This report presents an evaluation of the systematic error of the Navy Operational Global      Atmospheric Prediction System (NOGAPS 2.1) for the winter of 1983/84. The      systematic error is just the man of the forecast error. The error is the difference between      the NOGAPS forecast and the NOGAPS analysis at verification time. The fields      examined are the 9235, 500 and 250 mb heights, the 925 and 250 mb winds, the      925-500 mb thickness and sea-level pressure. The forecasts are those started on the      0000 GMT watch for 120 h and are evaluated at intervals of 24 hours. The error and      analysis fields are also fourier decomposed along latitude circles to ascertain the scale      structure of the errors. In addition, anomaly correlations and root mean square error are      computed over various latitude bands to provide an overview of the model performance.      Keywords: Numerical weather forecasts; Error analysis.
