Multifractal intermittency of Eulerian and Lagrangian turbulence of ocean temperature and plankton fields
Multifractal intermittency Eulerian and Lagrangian turbulence ocean temperature plankton fields
<
2009/11/16
In this paper, we present evidence that intermittency of Eulerian and Lagrangian turbulence of ocean temperature and plankton fields is multifractal and furthermore can be analysed with the help of un...
Energy densities as a function of frequency of the vertical and relative horizontal velocities of water in the deep ocean as measured at clusters of neutrally buoyant floats are compared for different...

Selecting Record Length Near-Bed Turbulence Measurements Digitization Rate
<
2009/2/16
Measured values of turbulence parameters (such as mean, variance or covariance of velocity) will depend on the record length and digitization rate chosen for their computation. Six factors which gover...
Equilibrium Geostrophic Turbulence I：A Reference Solution in a β-Plane Channel
Equilibrium Geostrophic Turbulence β-Plane Channel Reference Solution

2009/2/10
A numerical solution is calculated for quasi-geostrophic, adiabatic, baroclinic, wind-driven flow in a β channel. The rates of driving and dissipation are such that the solution is turbulent in equili...
An Experimental Study of Turbulence Behind Towed Biplanar Grids in a Salt-Stratified Fluid
Turbulence Salt-Stratified Fluid Towed Biplanar Grids

2009/2/8
Biplanar gods were towed down a 30 m long tank of stratified water at 10–60 cm s−1. Stratifications from N=0.2 to 0.5 rad s−1 were used. Single electrode conductivity probes repeatedly pro...
In January and February 1979 a free-fall vehicle was deployed at 150°W near the equator to sample velocity and temperature microstructure. Airfoil shear probes on the vehicle are able to resolve the p...
