Numerical modelling of the evolution of internal bores and generation of internal solitons at the Malin Shelf Efim Pelinovsky and Tatjana Talipova Department of Applied Hydrodynamics and Nonlinear Acoustics, Institute of Applied Physics, Russian Academy of Sciences, Nizhny Novgorod, Russia Justin Small Defence Evaluation Research Agency, Winfrith, Dorset , UK 1. This process is important to understand as a generator of internal solitons. Further, knowledge of the evolution of bores and waves may allow prediction forward from observations at a fixed point to distant points.
Results indicate close agreement in the cases studied for single sources.
The thermistor chain resolved the internal waves well, with a 20 second sub-sampling from the original 1 Hz sampling, but the ADCP, averaging over 2 minutes, often smoothed out the high frequency waves. With the needed accuracy the vertical displacement is presented as . The effect of variable depth and the horizontal variability of the density stratification at the Malin Shelf Edge can be included also in the model. Parameter Q is constant practically. Averaged values and standard deviations of the coefficients of the generalised Korteweg - de Vries equation are given in the last row of Table 1.
