Atmosphere-Ocean Coupling
The dynamic interaction and exchange of energy, moisture, and momentum between Earth's atmosphere and oceans that fundamentally shapes global climate patterns.
Atmosphere-Ocean Coupling
Atmosphere-ocean coupling represents one of the most critical interactions within Earth's climate system, governing everything from daily weather patterns to long-term climate evolution. This complex relationship serves as a cornerstone of modern climate models and our understanding of global climate dynamics.
