The atmospheric boundary layer is particularly challenging to model in conditions of stable stratification, which can be associated with intermittent or unsteady turbulence. We develop a modelling approach to represent unsteady mixing possibly associ

December 25 marks the 75th anniversary of the famous Ukrainian specialist in mathematical physics, winner of the State Prize of Ukraine in Science and Technology (2001) and the M.M. Krylov Prize of the NAS of Ukraine (2010), Head of the Department of

The lower nocturnal boundary layer is governed by intermittent turbulence which is thought to be triggered by sporadic activity of so-called sub-mesoscale motions in a complex way. We analyze intermittent turbulence based on an assumed relation betwe

Essentially generalizing Lie's results, we prove that the contact equivalence groupoid of a class of (1+1)-dimensional generalized nonlinear Klein-Gordon equations is the first-order prolongation of its point equivalence groupoid, and then we carry o

We present results on the modeling of intermittent turbulence in the nocturnal boundarylayer using a data-driven approach. In high stratification and weak wind conditions, thebulk shear can be too weak to sustain continuous turbulence and the sporadi

Predictability of the atmospheric boundary layer is impaired by possible rapid transitions between fully turbulent states and quiescent, quasi-laminar states. Such rapid transitions are observed in Polar regions or at night when the atmospheric bound

Parameter estimation for non-stationary stochastic differential equations (SDE) with an arbitrary nonlinear drift, and nonlinear diffusion is accomplished in combination with a non-parametric clustering methodology. Such a model-based clustering appr
