Abstract: Satellite data is used to investigate the dynamics of a special thermo-hydrodynamic phenomenon called "thermal bar" (a zone of descending water with the temperature of maximum density, equal to～4℃) in Lake Ladoga and Lake Onega, Russia. A theoretical model of the thermal bar progression is also applied and compared with the satellite data. The study shows that information on water surface temperature distribution obtained from satellite data provides a good means for monitoring and tracking the thermal bar. The comparison between predictions from the simple theoretical model describing the movement of the thermal bar with observations show good agreement for both investigated lakes.
