摘要
Internal waves are often neglected in oceanic heat transport estimates. Using 487 glider profiles from the northern South China Sea, we quantify the contributions of semidiurnal, diurnal, and near-inertial waves to heat transport. Near-inertial waves induce the strongest temperature anomalies (up to 0.5°C in the upper 1000 m), followed by diurnal waves, with semidiurnal waves being the weakest. Although the three wave types contribute only 6.7% to total heat transport on average, instantaneous effects reach 827% above background. Near-inertial and diurnal waves dominate temporally and spatially, with near-inertial waves exhibiting broader spatial influence. Correlation analyses trace near-inertial waves to remote generation in the Luzon Strait, whereas diurnal waves are locally transferred from near-inertial waves. In energetic strait environments, internal-wave-induced heat transport—particularly from near-inertial waves—must be included in heat budget analyses.
