外文摘要：Sea surface temperature (SST) responses induced by tropical cyclones (TCs) represent important ocean feedback that modulates subsequent TC development, yet their evolution relative to TC life cycle remains insufficiently quantified. Most previous studies examine SST responses using fixed temporal windows or intensity-centered snapshots, which obscure the continuous evolution of ocean responses along the TC track. Here, we investigate the life cycle-resolved SST responses to 461 TCs (2002-24) over the western North Pacific using satellite observations and a normalized track-relative projection. Normalizing lifespans to a unit coordinate enables consistent SST evolution comparisons across TCs with diverse durations and translation characteristics. Composite analyses reveal a robust and systematic cold-wake evolution across four TC groups categorized by intensities and translation directions. Maximum SST cooling consistently lags the TC center by 10%-16% of the normalized life cycle. Stronger and northward-moving TCs generate larger cooling magnitudes and more compact cold wakes, whereas westward-moving TCs produce weaker cooling patterns. Sensitivity analyses further show that the cooling magnitude is modulated by TC size, translation speed, and season, but the main spatial pattern remains robust. SST cooling also exhibits a persistent right-of-track asymmetry associated with stronger wind stress and inertial ocean responses. The magnitude and structure of the cooling further depend on upper-ocean stratification and surface wave conditions. These results provide a life cycle-based framework for characterizing TC-induced ocean feedback and improving representation of air-sea coupling in climate models and TC prediction systems under climate change scenarios.
