Understanding the complex “warming chain” in sea regions is crucial for predicting the cascading impacts of oceanic heat interactions on global climate stability. This study employs network analysis to explore the interactions of sea surface temperature (SST) across oceanic regions, focusing on complex heat transfer dynamics. By applying a heat equation approach, sea regions are represented as nodes and their directional heat transfer relationships as edges, allowing the identification of key oceanic regions in terms of inward and outward heat distributions. The analysis highlights previously reported influential oceanic communities, such as those linked to the El Niño-Southern Oscillation (ENSO) system and the mutual interactions between the Indian and Atlantic Oceans, and underscores the role of these regions in global heat distribution, offering insights into oceanic temperature dynamics and potential implications for climate stability.
