Abstract

An approximate formula expressing the variations of ray travel times in terms of range-averaged characteristics of temperature inhomogeneities is derived. This formula essentially reduces the underdetermination of the inverse problem, which appears in the reconstruction of climatic variations of the average ocean temperature from acoustic measurement data. The efficiency of the suggested approach is confirmed by numerical simulations.
