A new reference-quality precipitation gauge wind shield [PDF]
Atmospheric Measurement Techniques, 2023 Gauge-based precipitation measurements suffer from undercatch due to the effects of wind, with solid-precipitation measurements especially susceptible to such errors.

Log-Skew-Normality of Ocean Turbulence [PDF]
Physical Review Letters, 2021 The statistics of intermittent ocean turbulence is the key link between physical understanding of turbulence and its global implications. The log-normal distribution is the standard but imperfect assumed distribution for the turbulent kinetic energy dissipation rate.

The quantification and correction of wind-induced precipitation measurement errors [PDF]
Hydrology and Earth System Sciences, 2017 Hydrologic measurements are important for both the short- and long-term management of water resources. Of the terms in the hydrologic budget, precipitation is typically the most important input; however, measurements of precipitation are subject to large

Propagation of a Lorentz Non-Uniformly Correlated Beam in a Turbulent Ocean
Photonics, 2023 We study the propagation characteristics (spectral intensity and degree of coherence) of a new type of Lorentz non-uniformly correlated (LNUC) beam based on the extended Huygens–Fresnel principle and the spatial power spectrum of oceanic turbulence.

Effect of oceanic turbulence with anisotropy on the propagation of multi-sinc Schell-model beams
Results in Physics, 2022 Using the extended Huygens-Fresnel principle, the expressions for the cross-spectral density function of both the circular and square multi-sinc Schell-model (MSSM) beams propagating in an anisotropic oceanic turbulent medium have been derived ...

Experiments on wave turbulence : the evolution and growth of second sound acoustic turbulence in superfluid 4He confirm self-similarity. [PDF]
, 2010 We report our experiments on the formation of second sound acoustic turbulence in superfluid 4He. The initial growth in spectral amplitude follows power laws that steepen rapidly with increasing harmonic number n, corresponding to a propagating front in ...

Turbulence and fossil turbulence in oceans and lakes
Chinese Journal of Oceanology and Limnology, 2004 Turbulence is defined as an eddy-like state of fluid motion where the inertial-vortex forces of the eddies are larger than any of the other forces that tend to damp the eddies out. Energy cascades of irrotational flows from large scales to small are non-turbulent, even if they supply energy to turbulence. Turbulent flows are rotational and cascade from
