Changes associated with the PV eddy closure (GM_K3D) include: o To improve efficiency the call to solve for the eigenvectors only happen once every GM_K3D_vecFreq seconds. This required the following changes: - read and write pickup files for the eigenvectors and deformation radius (gmredi_read_pickup.F and gmredi_write_pickup.F) - making the number of modes (GM_K3D_NModes) a parameter which must be specified at compile time in GMREDI.h - A new namelist variable, GM_K3D_vecFreq - Added modesC, modesW, modesS and Rdef to the common block o If the CPP option use_lapack is undefined, then a WKB approximation to the eigenvectors and deformation radius is now used (although, it seems unstable; so for the moment an error is raised in gmredi_check if GM_K3D is defined but use_lapack is not). o Changed gmredi_calc_eigs returns the deformation radius rather than the deformation wavenumber o Fixed bug in calculation of tfluxX and tfluxY for the instance where the surface layer is the depth of the water column. o Added warning messages if there are problems with calculating eigenmodes and eigenvectors o Cleaned up code o Improved documentation o Rationalised diagnostics o Added some extra startup checks (gmredi_check)
Added a new eddy diffusivity parameterisation pkg/gmredi. More detailed description in tag-index.
