Abstract:
Surface and 500-mb charts were examined for periods between 1903 and 1950 to determine the most probable frontal positions to be intered on prognostic charts for a 500-mb forecast and a prediction of the situation of surface lows and their relative intensity. The recommended farthest penetration of a cold front for entry on prognostic charts for North America and the western Atlantic was 50 of the length of the line connecting 2 successive lows. For fronts lying east and west of 90 deg W, the penetrations will probably be subaveraged and above average, respectively. The penetration will tend to be subaverage if succeeding lows have about equal strength or the 500-mb flow between the lows is without a marked trough.
