Study of Natural Phenomenon of Thermal Bar: Field Observations, Laboratory, and Mathematical Modeling

Abstract

The paper provides a review of publications on the study of the natural phenomenon of the thermal bar. Results of field observations of this phenomenon in lakes in spring and autumn, offering insights into thermo-hydrodynamic processes in water bodies during these periods, are presented. In laboratory modeling studies of the thermal bar, instability mechanisms leading to its occurence and features of its movement are discussed. Theoretical works are considered, where various approaches to modeling the thermal bar are discussed, including modern hydrodynamic models. Special attention is paid to research on this phenomenon conducted at the Department of Physics of the Sea and Inland Water of the Faculty of Physics, Lomonosov Moscow State University.
