Statistical learning of nonlinear stochastic differential equations from non-stationary time series using variational clustering
Vyacheslav Boyko, Sebastian Krumscheid, Nikki Vercauteren
Parameter estimation for non-stationary stochastic differential equations (SDE) with an arbitrary nonlinear drift, and nonlinear diffusion is accomplished in combination with a non…
Detecting regime transitions of the nocturnal and Polar near-surface temperature inversion
Amandine Kaiser, Davide Faranda, Sebastian Krumscheid +2
Many natural systems undergo critical transitions, i.e. sudden shifts from one dynamical regime to another. In the climate system, the atmospheric boundary layer can experience sud…
Statistical investigations of flow structures in different regimes of the stable boundary layer
Nikki Vercauteren, Vyacheslav Boyko, Amandine Kaiser +1
A combination of methods originating from non-stationary timeseries analysis is applied to two datasets of near surface turbulence in order to gain insights on the non-stationary e…
Scale interactions and anisotropy in stable boundary layers
Nikki Vercauteren, Vyacheslav Boyko, Davide Faranda +1
Regimes of interactions between motions on different time-scales are investigated in the FLOSSII dataset for nocturnal near-surface stable boundary layer (SBL) turbulence. The non-…
