Abstract : A computer method for objective computation of adiabatic three-dimensional trajectories in the free atmosphere is presented. This technique utilizes a digital adaption of the graphical iterative method introduced by Danielsen (1961). The program is applied to a test case and is found to give generally satisfactory results. Some difficulties are encountered in cases of very low wind speeds and also in regions of strong anticyclonic wind shears. A method for inclusion of diabatic effects is outlined in detail. This approach may allow investigation of more complicated flow problems than have been previously possible. (Author)
