Abstract : The Fleet Numerical Weather Facility (FNWF), located at Monterey, California, has been producing 500-mb SD and SL analyses and forecast fields in their latest modified form since December 1964. These fields, designated as Beta Decomposition Patterns by FNWF, are elementary fields derived from the 500-mb pressure-height field, the SD-field being that of short-wave disturbances and the SL-field of long-wave disturbances. An investigation of these fields, both SD-analyses and forecasts and SL-analyses was undertaken in association with the National Meteorological Center's surface pressure analyses to determine possible relationships that may exist between the displacement of the surface low-pressure system and the 500-mb SD low-pressure centers and also the direction of the surface system's displacements with the 500 SL-analyses. The purpose of this investigation was to relate the 500-mb analyses and prognoses to the displacement of surface cyclones. (Author)
