New possibilities of animated analysis are considered associated with the use of the results of intermediate calculations, namely, vector fields of displacements, which represent, up to a normalization factor, the velocity field of small elements observed in the satellite imagery. If the observed scalar quantity is total precipitable water, then the corresponding vector field is the effective rate of advection of water vapor. By combining synchronous series of the scalar field of the observed quantity and the vector field of its motion, the advective flow through a given boundary of closed loop can be calculated. In the analysis of total precipitable water field, the result is the latent heat flux in MW. An algorithm is discussed for normalization and conversion into a spherical coordinate system of the vector fields of motion to obtain the final estimates of flux in standard units. Examples of calculations based on real satellite data are given.
Keywords: animated analysis, advective flux, latent heat
