In this paper we presented the analysis of two long time series of daily river flow data, 32
years recorded in the Seine river (France), and 25 years recorded in the Wimereux river …

Heavy particulate pollution events have frequently occurred in the North China Plain over
the past decades. Due to high emissions and poor dispersion conditions, issues are …

In the marine environment, many fields have fluctuations over a large range of different
spatial and temporal scales. These quantities can be nonlinear and non-stationary, and …

In this paper, an automated algorithm is developed, which is used to identify the spectral gap
during the heavy haze pollution process, reconstruct acquired data, and obtain pure …

In this paper we present an extended version of Hilbert-Huang transform, namely arbitrary-
order Hilbert spectral analysis, to characterize the scale-invariant properties of a time series …

Multi-scale systems, involving complex interacting processes that occur over a range of
temporal and spatial scales, are present in a broad range of disciplines. Several …

To obtain the differences in the turbulence structures between the light and heavy haze
pollution process, a light pollution episode (LPE) from November 3 to 72,017, and a heavy …

Converging flows at stream confluences often produce highly turbulent conditions. The
shear layer/mixing interface that develops within the confluence hydrodynamic zone (CHZ) …

This work investigates how turbulence in open-channel flows is altered by the passage of
surface waves by using experimental data collected with laboratory tests in a large-scale …

Turbulent motions in the Arctic stable boundary layer are characterized by intermittency, but
they are rarely investigated due to limited observations, in particular over the sea‐ice …
