This study introduces a convective velocity estimation method based on space-time correlations to enhance the temporal resolution of turbulent flow measurements using semi-Lagrangian techniques. The approach is evaluated using DNS data of a turbulent plane jet at 𝑅𝑒 = 10, 000. Comparison between correlation-based convective velocity 𝑈𝑐 and mean axial velocity 𝑈𝑚 reveals significant differences, with 𝑈𝑐 generally lower near the jet centreline and higher towards lateral edges. Spectral analysis demonstrates that 𝑈𝑐 based advection yields improved predictions of the turbulence spectrum compared to 𝑈𝑚. Future work will explore scale-dependent convective velocities and their impact on reconstructed frequency spectra.
