"2 Nov 1964." "CIR 4139." "A graphical technique is presented for the rapid computation of spot values of vertical velocity and precipitation rate from fields of vorticity advection and 1000-500-mb thickness advection, taking into account initial unsaturation, topography, latent heat effects, and height of cloud base. The procedure can be applied on both current and predicted charts and the effect of instability is incorporated by means of two regression equations"--Abstract.
