Abstract. Turbulent mixing in the ocean interior is mainly attributed to internal wave breaking; however, the mixing properties and the modulation effects of
mesoscale environmental factors are not well known. Here, the spatially
inhomogeneous and seasonally variable diapycnal diffusivities in the upper
Philippine Sea were estimated from Argo float data using a strain-based,
fine-scale parameterization. Based on a coordinated analysis of multi-source data, we found that the driving processes for diapycnal diffusivities mainly included the near-inertial waves and internal tides. Mesoscale features were important in intensifying the mixing and modulating of its spatial pattern. An interesting finding was that, besides near-inertial waves, internal tides
also contributed significant diapycnal mixing in the upper Philippine Sea.
The seasonal cycles of diapycnal diffusivities and their contributors
differed zonally. In the midlatitudes, wind mixing dominated and was
strongest in winter and weakest in summer. In contrast, tidal mixing was
more predominant in the lower latitudes and had no apparent seasonal
variability. Furthermore, we provide evidence that the mesoscale environment in the Philippine Sea played a significant role in regulating the intensity and shaping the spatial inhomogeneity of the internal tidal mixing. The magnitudes of internal tidal mixing were greatly elevated in regions of energetic mesoscale processes. Anticyclonic mesoscale features were found to enhance diapycnal mixing more significantly than cyclonic ones.
