  We attempt to gain some insight into the modeling of the generation of
internal waves produced by submarines traveling in the littoral regions of the
ocean with the use of high fidelity numerical simulations. These numerical
simulations are shown to be capable of simulating high Reynolds number flow
around bodies, including the effects of stable stratification. In addition, we
use the results of these detailed numerical studies to test and revise the
source distribution parameterizations of the near-field waves that have been
used in analytical studies based on linear theory. Such parameterizations have
been shown to be useful in initializing ray-tracing schemes that can be used
for computing wave propagation through realistic oceans with variable
background properties. For simplicity, we focus on the idealized case of a
spherical body traveling horizontally at constant speed through a uniformly
stratified fluid.
