EVOLUTION OF HOMOGENEOUS TURBULENCE IN 
A DENSITY-STRATIFIED MEDIUM. 
1. ANALYSIS IN FAR FIELD

The equations presented in [1] for the evolution of homogeneous 
turbulence  in a  density-stratified  medium  are  investigated 
analytically. The problem involves the small parameter e = Fr2. 
Applying variants of the small-parameter method, it is possible 
to  calculate the  frequency  of internal waves and a number of 
asymptotic regimes in the development of turbulent velocity and 
scalar fields  over time. The so-called far field of evolution, 
i.e., the field of large values of tau ( >> 1), is  considered,  
in  which  the  differential  order  of  the  initial system of 
equations is lowered.
