This study reviews the seasonality and temporal-spatial scale dependence of the air-sea relationship based on recent analyses of the relationship between surface turbulent heat flux and sea surface temperature. The contents include the representation, regional change, seasonal change and temporal and spatial scale variation of surface turbulent heat flux-sea surface temperature relationship as well as relative contributions of surface wind speed and sea-air humidity difference to changes in surface latent heat flux-sea surface temperature relationship. The surface turbulent heat flux-sea surface temperature relationship displays notable differences between the mid-latitude oceanic frontal zones and subtropical gyre regions. In the mid-latitude oceanic frontal zones, the oceanic process has a main contribution to sea surface temperature variations, indicative of an oceanic forcing, which is stronger in winter than in summer. In the subtropical gyre regions, surface turbulent heat flux plays a major role in sea surface temperature variations, indicative of an atmospheric forcing, which is more obvious in summer than in winter. In the western Arabian Sea, the oceanic process has an obvious influence on sea surface temperature variations in summer, indicative of an oceanic forcing, whereas the surface turbulent heat flux has a major influence in winter, indicative of an atmospheric forcing. In the Bay of Bengal, the South China Sea and the Philippine Sea, the atmospheric forcing is prominent in both winter and summer. In the mid-latitude ocean frontal zones during winter and the western Arabian Sea during summer, the oceanic forcing increases with the time scale, whereas in the other regions and seasons, there exists a transition from the atmospheric forcing in shorter time scales to the oceanic forcing in longer time scales with the transition time scale of about 20-40 days. In the mid-latitude oceanic frontal zones, the oceanic forcing decreases with the increase of the spatial scale and switches to the atmospheric forcing with the transition spatial scale shorter in summer than in winter. The atmospheric forcing usually enhances with the increase of the spatial scale.
