Improvement of Wavewatch III output through a wind speed modification based in boundary layer temperature variability

We present here an empirical method aimed at decreasing the error in the significant wave height calculated through the Wave Watch model. The errors are calculated as the difference between the modeled and the locally observed measurement. We hypothesize that this error would be reduced if the model used a well calibrated method to account for thermal variations within the surface boundary layer. We compared then this error for 2015 to the air sea temperature difference in order to find a potential relationship among them. The statistical analysis performed show a clear correlation between these variables, hinting for the need of introducing a correction for stability based on a linear relationship between the error and the air ocean temperature difference.
