The Results of the Study of the Influence of the Structure of the Temperature Field in the Atmosphere on the Formation of Convective Clouds

Abstract

The purpose of the work is to study the influence of the structure of the temperature field in the atmosphere on the values of the structural parameters of convective clouds by mathematical modeling methods. Materials and methods. One of the key directions in the development of the theory of cloud physics is the study of their system properties. These properties are the most important factors influencing the formation of the cloud structure. The methodology of the research consists in a comparative analysis of the parameters and structure of the initial and model clouds. The input data for the calculation of model clouds are obtained by varying the temperature values at all altitudes obtained as a result of aerological sounding of the troposphere at the Mineralnye Vody airport. Results and discussion. A comparative analysis of the parameters of the initial and model clouds showed that the structure and parameters of clouds are significantly influenced by the structure of the temperature field in the atmosphere. At the same time, temperature variations in the direction of increasing or decreasing within 1-2 % do not lead to significant changes in cloud parameters, and variations of the order of 10 % can lead to the formation of clouds that differ significantly from the original cloud. At the same time, an increase in temperature in the atmosphere (other parameters remain unchanged) leads to the formation of more powerful clouds and, conversely, the result of its decrease is a weakening of cloud formation processes in the atmosphere. Conclusions. The research results indicate the significant role of the interaction of clouds with the surrounding atmosphere, due to the structure of the temperature field in the atmosphere in the processes of cloud formation.
