We propose here a novel method of analysing turbulent momentum flux signals. The data for the analysis come from a nearly neutral atmospheric boundary layer and are taken at a height of 4 m above ground corresponding to 1.1×105 wall units, within the log layer for the mean velocity. The method of analysis involves examining the instantaneous flux profiles that exceed a given threshold, for which an optimum value is found to be 1 s.d. of the flux signal. It is found feasible to identify… 
Characterising Momentum Flux Events in High Reynolds Number Turbulent Boundary Layers
The momentum flux in a canonical turbulent boundary layer is known to have a time-series signature that is characterised by a highly intermittent variation, which includes very short periods of
Momentum flux fluctuations in wall turbulence: A formula beyond the law of the wall
Within wall turbulence, there is a sublayer where the mean wall-normal flux of the streamwise momentum is constant and related to the logarithmic wall-normal profile of the mean streamwise velocity.
Turbulence and turbulent flux events in a small estuary
Relatively little systematic research has been conducted on the turbulence characteristics of small estuaries. In the present study, detailed measurements were conducted in a small subtropical
A scale-wise analysis of intermittent momentum transport in dense canopy flows
Abstract We investigate the intermittent dynamics of momentum transport and its underlying time scales in the near-wall region of the neutrally stratified atmospheric boundary layer in the presence
Persistence behavior of heat and momentum fluxes in convective surface layer turbulence
The characterization of heat and momentum fluxes in wall-bounded turbulence is of paramount importance for a plethora of applications, ranging from engineering to Earth sciences. However, how the
A DNS Study of entrainment in an axisymmetric turbulent jet as an episodic process
This investigation is based on a DNS of a steady self-preserving incompressible axisymmetric turbulent jet at a Reynolds number of 2400. The DNS data enable accurate maps of the outer irrotational
Persistence analysis of velocity and temperature fluctuations in convective surface layer turbulence
Persistence is defined as the probability that the local value of a fluctuating field remains at a particular state for a certain amount of time, before being switched to another state. The concept
A breaking tidal bore is a highly turbulent transient process that may affect the natural estuarine system. Like many natural process flows, the tidal bore flow motion is dominated by coherent
Revisiting the role of intermittent heat transport towards Reynolds stress anisotropy in convective turbulence
Abstract Thermal plumes are the energy-containing eddy motions that carry heat and momentum in a convective boundary layer. The detailed understanding of their structure is of fundamental interest
Geometry and organization of coherent structures in stably stratified atmospheric boundary layers
Global intermittency is observed in the stably stratified Atmospheric Boundary Layer (ABL) and corresponds to having large nonturbulent flow regions to develop in an otherwise turbulent flow. In this


Turbulent bursts in a near-neutral atmospheric boundary13; layer - part I
The high Reynolds number boundary layer data obtained over the lowest 300m of a nearly neutrally stable atmospheric boundary layer at the Boulder Atmospheric Observatory13; are analysed here to
Energy Events in the Atmospheric Boundary Layer
Turbulent velocity fluctuations in the atmospheric boundary layer are analysed using the VITA technique, with a view to understand the relation of the special events detected by the technique with
The detection and measurement of turbulent structures in the atmospheric surface layer
Turbulence data from the planetary boundary layer (PBL) indicate the presence of deterministic turbulent structures. These structures often show up as asymmetric ramp patterns in measurements of the
Measurements of the structure of the Reynolds stress in a turbulent boundary layer
Additional experimental studies of the structure of Reynolds stress which supplement our previous work (Willmarth & Lu 1971) are reported. The velocity at the edge of the viscous sublayer is again

Horizontal velocity data recorded in the atmospheric boundary layer at Boulder, Colorado and Cabauw, the Netherlands under near-neutral conditions, are analysed here by the Variable Interval Time
The ‘bursting’ phenomenon in a turbulent boundary layer
Using a hot wire in a turbulent boundary layer in air, an experimental study has been made of the frequent periods of activity (to be called ‘bursts’) noticed in a turbulent signal that has been

Extensive visual and quantitative studies of turbulent boundary layers are described. Visual studies reveal the presence of surprisingly well-organized spatially and temporally dependent motions

On the wall structure of the turbulent boundary layer
The wall structure of the turbulent boundary layer was examined using hot-wire rakes and conditional sampling techniques. Instantaneous velocity measurements indicate a high degree of coherence over
Structure of the Reynolds stress near the wall
Experimental studies of the flow field near the wall in a turbulent boundary layer using hot-wire probes are reported. Measurements of the product uv are studied using the technique of conditional
