MIM
What is MIM?
Mass-weighted Isentropic zonal Means (MIM) facilitates to exactly express the finite-amplitude effects and lower boundary conditions for wave-mean flow interactions
MIM diagnostic scheme
This is the software package to analyze the atmospheric general circulation based on mass-weighted isentropic zonal means (MIM). The mean-meridional circulation, wave-mean flow interactions and energy conversion rates can be derived from conventional grid meteorological data, for example, reanalysis data.
