全球极端海洋热浪驱动机制揭示

Core Insights - The research conducted by Ningbo Oriental University and Southern University of Science and Technology reveals the driving mechanisms behind the extreme ocean heatwaves of 2023, providing crucial scientific evidence for understanding and predicting future extreme ocean events [1][2] Group 1: Research Findings - The study constructed the world's first mixed-layer heat budget diagnostic framework based on high-resolution ocean reanalysis data, which quantitatively characterizes the unprecedented features of global ocean heatwaves in terms of intensity, duration, and spatial coverage in 2023 [1] - The research identified different driving mechanisms for ocean heatwaves in four key global ocean regions, including enhanced shortwave flux and shallower mixed layers in the North Atlantic and North Pacific, reduced cloud cover and increased advection in the Southwest Pacific, and increased oceanic advection in the tropical East Pacific [1] Group 2: Importance of Earth System Science - Developing Earth system science is crucial for revealing the intrinsic mechanisms of complex climate phenomena, enhancing global climate prediction capabilities, and formulating scientific response strategies [2] - Establishing a physics-based forecasting system, strengthening real-time monitoring of multiple ocean factors, and conducting in-depth research on early warning of extreme climate events are of significant practical importance for addressing future climate risks [2]
