pyshqg
pyshqg is a python solver for the Marshal and Molteni (1993) quasi-geostrophic (QG) model.
QG models express the conservation of potential vorticity over time and are
meant to describe the large-scale circulation of the atmosphere under specific hypotheses.
This QG model is very special, because it is expressed in spherical harmonics and
because it encapsulates complex physical processes.
