Abstract : Research to formulate objective weather analysis and forecasting aids, and to investigate the utility of the objective quantities in naval task force operations is described. The objective aids are calculated by use of an electronic computer. Methods based upon single-station techniques for analysis of rawinsoundings are presented for computing wind shear, lapse rate, thermal advection, the direction towards the most unstable air, and a parcel stability index. These quantities are useful in identifying phenomena such as fronts, troughs, the tropopause, and the level of maximum wind. Average values of height, temperature, humidity, and wind components are computed in six arbitrarily defined layers for purposes of representing the gross atmospheric structure. A simple computer technique for calculating kinematical values of horizontal divergence, vorticity, deformation, vertical motion, and geostrophic departures from layeraveraged wind and height data at three stations is developed and demonstrated for an area comprised of the midwestern United States.
