Significant problem in present climate theory is the consideration of rapidly changing wind-dependent parameters when modeling the dynamics of the MBL depth. Perceptible errors in the simulation of the mixed layer are due to Langmuir and turbulent mixing. The paper presents a way to modernize the one-dimensional model of the mixed layer by Niiler-Kraus using a multiscale turbulence model, which takes into account three parameters of turbulence generation from wind: current velocity shear, surface wave nonlinearity and wave breaking. The verification of the model is presented by field data collected in the coastal zone of the Black Sea on a stationary oceanographic platform of the Marine Hydrophysical Institute of the Russian Academy of Sciences. The model working is evaluated with different variability of wind speed and direction. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
