Classification of marine heatwaves in the South China Sea and their thermodynamic features
摘要
Abstract
近年来南海海洋热浪发生频率显著上升,但调控其变化的热力与动力过程的相对作用尚不明确.本研究分析了1982至2021年的南海海洋热浪事件,根据海洋热浪期间海表温度的变化趋势将其划分为增强型和减弱型两类.混合层热收支分析表明,由潜热通量主导的热力过程对调控南海海洋热浪(尤其是衰减型)至关重要.然而,在增强型海洋热浪中,动力过程主导的事件比例(40％)与热力主导型(47％)近乎相当.本研究强调了动力过程在塑造南海海洋热浪中的重要性,并探讨了热带气旋对南海海洋热浪可能产生的影响.关键词
