New Zealand
This page describes a numerical simulation of gravity waves over New Zealand's
south island.
Computational Domain
The layout of the of the simulation is shown in the figure below. The origin is located at
Mount Cook (43.5950° S, 170.1418° E).
The computation grid uses horizontal mesh spacings of 500 m in a region slightly
larger than the south island land mass. The mesh is then stretched gently to
the lateral boundaries. The vertical grid uses uniform spacing of 500 m up to
an altitude of 140 km.
Inviscid wall boundary conditions are used and
the surface whereas characteristic (radiative) conditions are used at the
lateral and top boundaries.
