Single Column Modeling (SCM) is a technique in which only a single vertical column from the grid of a GCM is integrated forward in time. The boundary conditions and larger-scale forcings are prescribed, usually obtained from a larger-scale model and/or observations. The suite of subgrid-scale parameterizations of the GCM is free to act, and can create their own unique model state. This can give insight into the behavior of parameterizations at process level, and can help in understanding model biases as diagnosed in a GCM. | Single Column Modeling (SCM) is a technique in which only a single vertical column from the grid of a GCM is integrated forward in time.

Another approach for introducing simple feedbacks between resolved and parameterized scales is to simulate a set of neighboring single column models on a small horizontal grid. While in each column the parameterized physics acts as usual, a dynamical core can then takes care of any horizontal interactions that might develop as a result of variations among the columns. The set of columns thus become interactive, | Another approach for introducing simple feedbacks between resolved and parameterized scales is to simulate a set of neighboring single column models on a small horizontal grid.

An additional advantage in this respect is that the LES is a lot simpler in its setup compared to a GCM, which can enhance the transparency of any numerical experiments, |
