The software package, realizing the calculation and graphics visualization of asymptotic behavior at big time of dominant terms of velocity vector components at 2D motion of rotating stratified liquid, is developed. The mathematical model, which lies at the basis of the software package, is presented. The structure of the software package is described. The application of the software package in the study of fluctuations in stratified fluid is shown.

Keywords: stratified rotating liquid, mathematical model, software package, asymptotic behavior, dominant terms of the asymptotic forms
