Use of Analytical Modeling and Limited Data for Prediction of Mesoscale Eddy Properties.

Abstract

The use of analytical modeling in the study of oceanic eddies is considered. Limited observational data, in combination with eddy models, can be used to obtain analytical approximations to environmental effects, including current and temperature perturbations, throughout the eddy. Techniques which efficiently use discrete measurements are presented to accurately specify any given analytical model containing an arbitrary number of parameters to an observed eddy. Questions of unique parameter specification and data sufficiency are considered for various data types and amounts, using a previously-derived eddy model. Examples with bathythermograph data are presented, in which eddy size, strength, and center positon are to be determined. AXBT data is emphasized, and an investigation is made of the influence of the number of such instruments on the accuracy of parameter estimates.
