fixed 140818 runs to run the same length as 140803/05. maybe should not have rerun all, but tried various different things to get tracer working better. like also gridsize?
in correcting the time range for 140818, also copied all other attributes of jet2.h, of course, so ran the same thing many times. For now, satisfied with the fact that age tracer does better with shorter time step, but not super substantially. Might try running more with even shorter ones and see how long they take. Looking more concretely into including a diffusivity though.
talked to MSpall today. He suggests doing sensitivity to outflow conditions. Also, talked about adding diffusivity to model, which he suggests given what my output looks like. Should not change dynamics in my case since using a layer model.
results from 140821 took a very long time (5 days) to run and seem to reflect the same issues that mike pointed out, of very small scale features being present. will likely revert to lower res for now until some kinks are ironed out. also note that many dimensions that i insert are grid size dependent, evident here in sponge layer size and topography size. will now try running a set with focus on diffusing tracer more effectively
new thought that in 140821 time step may have been too large for grid size so that base case age diverged exponentially. difftracer runs look identical to base (except for weird enstrophy time series of basematch), so either the time step or other difficulty is overshadowing everything else, or implementation of diffusion did not work.
started 140827 with a large range of diffusivities
