THE EFFECT OF DEFORMATION IN THE WIND FIELD ON THE LARGE-SCALE HORIZONTAL DISPERSION OF CLUSTERS IN THE ATMOSPHERE,

Abstract

The deformation of air bodies in the horizontal flow is studied in absence of small-scale tur bulent diffusion. On the basis of kinematic models, formulas are evaluated which show the increase of the mean square distance of mate rial particles from the gravity center of each cluster of particles. The results are compared with statistics on the dispersion of air trajec tories in the barotropic model corresponding to the development of the flow on the northern hemisphere in a period of 8 days. The phenomenon of arrangement of material bands along the cur rents is explained as a property of fluid motion. The knowledge of the deformation renders it pos sible to get a quantitative explanation of that process. (Author)
