The problem of lack of fresh water in many arid regions in a world becomes more and more significant. The paper intends to analyze and optimize the thermal upflow combination with hygroscopic particles to develop the method of their combination for precipitation enhancement. The purpose of presented model is method of dynamical calculations of the spatial concentration of hygroscopic or ice-forming particles inside artificially heater air jet. As a result, most important parameters of thermal jets are indicated, analyzed and calculated, such as power, air velocity w(z,r) in altitude z, temperature decrease T(z), the atmospheric instability influence and bounce affection. The jet’s characteristics are combined with powder motion and result analytical formulas for evaluation were presented with calculations of the typical examples. The practical significance of the work is the possibility of preliminary calculations and optimization the parameters of created thermal jet and artificially added mass of powder to form clouds and precipitation enhancement in practical realization in field’s experiments.
