Abstract : The Fleet Numerical Weather Central Analog Forecast Program uses a digitized data bank of 500 mb, surface and zonal wind data for the period 1946-1969. The program searches the data bank for data fields within 30 days of the forecast date and a screening process ultimately selects the best hemispheric analog. The screening technique employs correlation in space and time of 500 mb and 1000 mb large and small scale components together with indices of the zonal wind profile. The analog forecast has been computed operationally twice a week since 1 March 1969. The analog forecasts are transmitted via high-speed data links to Fleet Weather Centrals in Guam; Pearl Harbor; Norfolk, Virginia and Rota, Spain. (Author)
