Π-ML: A dimensional analysis-based machine learning parameterization of optical turbulence in the atmospheric surface layer
Maximilian Pierzyna, Rudolf Saathof, Sukanta Basu
Turbulent fluctuations of the atmospheric refraction index, so-called optical turbulence, can significantly distort propagating laser beams. Therefore, modeling the strength of the…
A novel approach for deriving the stable boundary layer height and eddy viscosity profiles from the Ekman equations
Sukanta Basu, Albert A. M. Holtslag
In this study, we utilize a novel approach to solve the Ekman equations for eddy viscosity profiles in the stable boundary layer. By doing so, a well-known expression for the stabl…
Revisiting and revising Tatarskii's formulation for the temperature structure parameter () in atmospheric flows
Sukanta Basu, Albert A. M. Holtslag
In this paper, we revisit a well-known formulation of temperature structure parameter (), originally proposed by V.~I.~Tatarskii. We point out its limitations and propose a…
Turbulent Prandtl number and characteristic length scales in stably stratified flows: steady-state analytical solutions
Sukanta Basu, Albert A. M. Holtslag
In this study, the stability dependence of turbulent Prandtl number () is quantified via a novel and simple analytical approach. Based on the variance and flux budget equatio…
Addressing the Grid-size Sensitivity Issue in Large-eddy Simulations of Stable Boundary Layers
Yi Dai, Sukanta Basu, Björn Maronga +1
In this study, we have identified certain fundamental limitations of a mixing length parameterization used in a popular turbulent kinetic energy-based subgrid-scale model. Replacin…
On the Dissipation Rate of Temperature Fluctuations in Stably Stratified Flows
Sukanta Basu, Adam W DeMarco, Ping He
In this study, we explore several integral and outer length scales of turbulence which can be formulated by using the dissipation of temperature fluctuations () and other releva…
