What is the difference between the large scale and sub-grid scale Yanai Q1 equation?

23 December 2022 1 1K Report

Hello,

The terms on the RHS represent the subgrid-scale, and the ones on the LHS represent the large scale, yet both are coarse-grained-averaged. So why do the terms on the RHS still represent the subgrid scale?

Thanks

Alireza Gooneh

Both sides of an equation are equal when they are equal to a fixed value
