Multifractal Model of Atmospheric Turbulence Applied to Elastic Lidar Data

Iulian Alin Rosu et al.

Summary: This paper presents a multifractal interpretation of turbulent atmospheric entities as a complex system, with dynamics manifested on continuous yet non-differentiable multifractal curves. It discusses the minimal vortex of turbulent flow through theoretical considerations of multifractal structures and non-differentiable functions, leading to a general equation for the non-differentiable vortex and its energy dissipation. The study also uses lidar data to extrapolate relationships between turbulent energy dissipation and the minimal vortex, ultimately compiling altitude profiles into timeseries to compare with known literature.

Towards Possible Laminar Channels through Turbulent Atmospheres in a Multifractal Paradigm

Iulian-Alin Rosu et al.

Summary: This paper introduces turbulent energy cascade staging models developed through scale relativity theories for simulating complex atmospheric behavior. It is found that more complex gauges can exhibit more complex behavior, but parameterizing the solutions formed by these gauges can be challenging. However, a logistic-type approximation coupled with a simpler gauge model can reveal instances of non-chaotic behavior in turbulent flow.
