Features of analytical solutions of atmospheric diffusion equations show that the effect of wind shear and vertical diffusion on horizontal dispersion is important at great distances. Methods of using an analogue or a digital computer to solve the equations for all but very short distances are described. Computations indicate that the wind shear effect is probably dominant over a wide range, and these indications are confirmed by reference to broad and specific deductions from experimental data.
