Abstract

KRISSY is a computer model for generating three-dimensional wind flows in complex terrain from data that were not or perhaps cannot be collected. The model is written in FORTRAN IV This guide describes data requirements, modeling, and output from an applications viewpoint rather than that of programming or theoretical modeling. KRISSY is designed to minimize meteorological requirements―particularly for upper air data. It also includes a program option that derives vertical motion from a solution of the wave equation with momentum conservation. KRISSY differs from other mass-conserving wind flow models in these features and, therefore, is applicable to a broader range of meteorological conditions.
