Turbulence is everywhere -- it rattles our airplanes and makes tiny whirlpools in our bathtubs -- but it's one of the least understood phenomena in physics.Turbulence occurs when an ordered fluid flow...
Coupling a new turbulence parametrization to RegCM adds realistic stratocumulus clouds
turbulence parametrization RegCM adds realistic stratocumulus
2014/12/10
To model stratocumulus clouds in the regional climate model, RegCM4.1, the University of Washington (UW)
turbulence parametrization has been coupled to RegCM. We
describe improvements in RegCM’s coa...
Magnetosphere-Ionosphere Coupling Through E-region Turbulence: Anomalous Conductivities and Frictional Heating
Anomalous Conductivities Frictional Heating
2017/3/22
Global magnetospheric MHD codes using ionospheric conductances based on laminar
models systematically overestimate the cross-polar cap potential during storm time by
up to a factor of two. At these ...

Many vital insights into the nature of turbulence in fluids have originated from experimental data obtained in geophysical flows. Geophysical data have often helped to stimulate the creation of new tu...
Spectral evolution of two-layer weak geostrophic turbulence.Part I:Typical scenarios
Spectral evolution two-layer weak geostrophic turbulence Typical scenarios
2009/11/16
Long-time evolution of large-scale geophysical flows is considered in a β-plane approximation. Motions in an infinite 2-layer model ocean are treated as a system of weakly nonlinear Rossby waves (weak...

A one-dimensional, nine-mode spectral model for temperature, velocity, and the mixing ratios of suspended and precipitating ice-particle components is shown to be consistent with ice-cloud observation...
Numerical simulation of ion dynamics in the magnetotail magnetic turbulence:On collisionless conductivity
Numerical simulation ion dynamics magnetotail magnetic turbulence collisionless conductivity
2009/11/13
The ion dynamics in the distant Earth's magnetotail is studied in the case that a cross tail electric field and reconnection parity magnetic turbulence are present in the neutral sheet. A test particl...
Turbulence:mechanics and structure of anomalous scaling
