Are there principles to guide eddy parameterizations?

چکیده
A “list as long as your arm” has described the range of principles that may be attempted for possible eddy parameterization schemes. We feel uncomfortably an attitude of “try and see” whether any particular principle “works” in any particular application. This note summarises a discussion which followed the body of presentations at ‘Aha. We ask if principles from general physics, especially notions of the 2 Law and entropy, can help clear a way. We ask if such ideas offer practical means to advance practical knowledge, and where major impediments may lie.

Can Large Eddy Simulation Techniques Improve Mesoscale Rich Ocean Models?
Large-eddy simulations (LES) differ from other fluid flow computations in that the largest eddies are explicitly resolved and the smaller eddies are modeled (as engineers call it) or parameterized (as oceanographers call it). Modeling the ocean and atmosphere inspired the first large-eddy simulations, but true large-eddy simulations of the ocean and atmosphere are surprisingly rare. Ocean model...
متن کاملThe Influence of Mesoscale Eddies on Coarsely Resolved Density: An Examination of Subgrid-Scale Parameterization
Coarse-resolution numerical models of ocean circulation rely on parameterizations of unresolved mesoscale eddy effects. In order to investigate the role of eddy-flux divergences in the density equation, the GFDL Modular Ocean Model (MOM) has been configured as a simple flat-bottomed channel model with sufficient resolution to represent mesoscale eddies. Eady-type baroclinic instability and a wi...
متن کاملInvestigating Underlying Principles to Guide Health Impact Assessment
Background Many countries conduct Health Impact Assessment (HIA) of their projects and policies to predict their positive and negative health impacts. In recent years many guides have been developed to inform HIA practice, largely reflecting local developments in HIA. These guides have often been designed for specific contexts and specific need, making the choice between guides difficult. The o...

1 The performance of five boundary layer parameterizations in the Weather 2 Research and Forecasting model is examined for marine boundary layer cloud regions 3 using a single column model version of the WRF model. Most parameterizations show a 4 poor agreement of the vertical boundary layer structure when compared with Large-Eddy 5 Simulation models. These comparisons against Large-Eddy Simula...
متن کاملThe Search for Underlying Principles of Health Impact Assessment: Progress and Prospects; Comment on “Investigating Underlying Principles to Guide Health Impact Assessment”
Health Impact Assessment (HIA) is a relatively young field of endeavour, and hence, future progress will depend on the planning, implementation and rigorous evaluation of additional HIAs of projects, programmes and policies the world over. In the June 2014 issue of the International Journal of Health Policy and Management, Fakhri and colleagues investigated underlying principles of HIA through ...
