Techniques for Estimating the Heights of Constant Pressure Surfaces.
Abstract
The analysis of upper air charts, particularly over ocean areas, is frequently inaccurate because of insufficient radiosonde, rawin and pibal observations. Hence, it becomes mandatory that the Naval aerologist supplement the meager number of actual upper air observations by extrapolations from known data at some lower level, generally from the sea level chart. There are several different techniques employed for such extrapolations, all of them, of course, being based on some form of the hydrostatic equation. It is the purpose of this publication to describe two such methods of extrapolation, together with the necessary diagrams and tables to obtain the estimates of the upper level data.
