Observed Meso‐Gamma Scale Variability of Air‐Sea Sensible Heat Flux in a Coastal Region

The meso‐gamma scale variability of air‐sea sensible heat flux was investigated using synchronized flux observations from two tower‐based platforms within 10 km over coastal regions. Observations revealed statistically weak correlations between spatial variability and both 10 m wind speed and air‐sea temperature difference . While roughly consistent between the two stations, significant discrepancies emerged, particularly along the parallel line connecting the two sites. Despite occasional variations at specific measurement points or times, the characteristics demonstrated statistical consistency between the two stations. Comparative analysis with the bulk algorithm indicated that bulk differences could partially explain observed variations. However, observed magnitudes substantially exceeded bulk estimates, and the heat flux exchange coefficients derived from observations differ by 1.6 times between the two stations. These findings highlight the necessity for enhanced high‐resolution direct flux measurements to validate parameterization schemes.
