Abstract: The closure problem for the convective turbulence of the shear-free and low to moderate wind atmospheric boundary layer is considered. Non-Gaussian parameterizations are developed for fourth-order moments based on a two-scale ...

Abstract: Climate models still have deficits in reproducing the surface energy and momentum budgets in Arctic regions. One of the reasons is that currently used transfer coefficients occurring in parameterizations of the turbulent ...

Abstract: The Millionshchikov hypothesis of quasi-normal distribution of fourth-order moments fails for convective conditions where the probability density functions of temperature and vertical velocity fluctuations are skewed. This ...
