The Lagrangian description of turbulence is characterized by a unique conceptual simplicity
and by an immediate connection with the physics of dispersion and mixing. In this article, we …

▪ Abstract Turbulence is ubiquitous in atmospheric clouds, which have enormous turbulence
Reynolds numbers owing to the large range of spatial scales present. Indeed, the ratio of …

We use silicon strip detectors (originally developed for the CLEO III high-energy particle
physics experiment) to measure fluid particle trajectories in turbulence with temporal …

Velocity field statistics in the inertial to dissipation range of three-dimensional homogeneous
steady turbulent flow are studied using a high-resolution DNS with up to N= 1024 3 grid …

▪ Abstract A Lagrangian description of turbulence has unique physical advantages that are
especially important in studies of mixing and dispersion. We focus on fundamental aspects …

Pressure fluctuations are an important ingredient in turbulence, eg in the pressure strain
terms which redistribute turbulence among the different fluctuating velocity components. The …

The scaling properties of one-and two-point statistics of the acceleration, pressure, and
pressure gradient are studied in incompressible isotropic turbulence by direct numerical …

An understanding of Lagrangian statistics is of great importance in the ongoing effort to
develop both fundamental and practical descriptions of turbulence. This was recognized …

The pressure spectrum in homogeneous steady turbulence is studied using direct numerical
simulation with resolution up to 1024 3 and the Reynolds number R λ between 38 and 478 …

The bane of infrasound signal detection and characterization is the noise generated by
wind. In this chapter, we review the physics of wind, current theories on how wind can …
