Abstract:

Objective techniques are being developed for interpreting grid-point analyses and prognoses produced by computerized dynamical models in terms of concomitant surface-weather conditions. Multiple regression equations were derived to express statistical relationships between surface-weather variables and derived upper-air parameters representing pertinent physical processes taking place between the surface and the 500-mb level. These upper-air predictor parameters were derived from observed height and thickness values and the climatological statistics of these values. The work presently being conducted and plans for future work are discussed. Improvement is being sought by the definition of better predictor parameters to represent orographic effects and by the incorporation of moisture cloud amount information now available from dynamical models. The equations will be tested on real-time upper-air prognoses and readied for use in an operational test by the Air Weather Service by September 1965. Author
