It is well established in the literature that there are many things in the climate system smaller than the state of Delaware [citation needed]. However, computational constraints force climate models to use grid cells of about that size, and so many processes go unresolved. In this talk I will provide a meandering update on my work developing data-driven parameterizations to allow models to include the effects of SDS (sub-Delaware scale) gravity waves using tree models. I’ll begin with a brief refresher on my project and where I’ve gotten to so far, in case you’ve misplaced the 10-15 pages of notes you took last time I talked. I’ll then go into more detail than anyone would like discussing a computational tool I needed to build for this work and compare it to existing libraries. Time permitting, I’ll conclude by waving my hands a bit about better understanding differences in online performance of parameterizations that seem similar offline.
