Temporal correlation function of the internal-wave displacement at as a function of time lag. The temporal correlation is the normalized spatio–temporal covariance of Eq. (28) at zero horizontal separation. The e-folding coherence time is approximately . The solid horizontal line is plotted at the correlation function value .

FIG. 4.

Temporal correlation function of acoustic power and forward field for source-receiver separation as a function of time lag for various possible GM energy levels. The temporal correlations of acoustic power and forward field are the normalized temporal covariances of Eqs. (17) and (18), respectively. The e-folding coherence time varies between 7 and depending on the internal wave energy level. The temporal correlation functions of the acoustic power and forward field are plotted with dashed and solid lines, respectively. The solid horizontal line is plotted at the correlation function value .
