Developing Techniques for Automated Forecasting of Clear Air Turbulence.

Abstract

The work reported is directed toward adapting the scheme developed by the Stanford Research Institute for automated forecasting of Clear Air Turbulence (CAT). An important element of the scheme is the relation of CAT OCCURRENCE TO METEOROLOGICAL PARAMETERS. Multi-dimensional contingency tables are developed for specifying the probability of occurrence of CAT from values of meteorological parameters. The table generating procedure will require modification to solve the problem of the sparcity of data which occurs in some of the cells of the tables. Nevertheless, the reductions of variance obtained with the developmental set of data suggest that multi-dimensional contingency tables may produce effective specification of the probability of CAT from meteorological parameters in an automated system.
