Thermal structure refers to the distribution of temperature in a given system or environment, such as the atmosphere, ocean, or Earth's interior. It includes the variations in temperature with depth, location, and time, and plays a crucial role in shaping the physical and chemical processes within these systems. Researchers studying thermal structure aim to understand how heat is transferred and distributed within these systems, as well as the factors influencing these processes. This research area is important for various fields, including meteorology, oceanography, geology, and environmental science, as it provides insights into the dynamics and behavior of these systems and helps in predicting and mitigating potential impacts of climate change and natural hazards.
