This report summarizes preliminary work undertaken inconsideration of the use of stochastic approaches to climate modeling. It includes a survey of the difficulties involved with representation of atmospheric dynamics for climate questions and some recommendations for directions of research needed to deal with them. The results of two specific analytic studies are included. The first demonstrates that the complete stochastic formulation in terms of an infinite hierarchy of moment equations is directly applicable to time-averaged as well as instantaneous representations of the dependent variables. The second analytic result presents a methodology for time and space truncation of the deterministic predictive part of the equations of atmospheric motion that can considerably reduce computation times for climatic and weather models.
