Based on the atmospheric remote sounding data obtained by the radiometer SEVIRI of the European geostationary meteorological satellites Meteosat-8 and Meteosat-9 calculated were the dynamic characteristics of the middle and upper troposphere and the lower stratosphere (the horizontal wind speed vector, V, the coefficient of horizontal mesoscale turbulent diffusion, Kd, and vorticity, rotV) in the zones of tropical cyclones origination and development in the Atlantic. The calculations were made with the method developed by the authors. It is based on the use of heterogeneities of a conservative impurity concentration field (water vapor and ozone) as tracers and the correlation-extreme algorithms. The evolution of the dynamic characteristics in the process of tropical cyclone Bertha (2008) generation and development has been analyzed. The fields of dynamic characteristics of the upper troposphere were constructed for the model of a composite cyclone at the stages of a tropical depression, a tropical storm and a hurricane.
