started investigation into the zonal line at -20 by running longer and looking at different parts of the time series. also am trying to move away from the wall to get rid of those recirculations in the corner of the upper layer. i should also make sure to look back at other runs to see when they showed up. next steps: 1) try out different dwbc shapes as part of a search for the right base case. 2) get the topo/coast framework in.
started some different dwbc runs still under 140521 though the date has progressed. also cleared out extraneous scripts and am just changing willynilly, should also rename to reflect the fact that I am just gonna keep changing it and i have other versions saved. note that the confusion i had about the line appearing suddenly coincides with a shift from looprunning to all in a row, so that the previous means do not average over as long. want to look into a really steady dwbc further.
looked at 140521 runs after long weekend, changing the dwbc shape did not work, should look through and try again, monitoring this time. the line at -20 is persistent even for a longer run and moving the dwbc away from the wall, try playing with sponge layer size/ existence to see if that is the root cause. finally, cursory look at the movies produced from these runs do not look great- something to look into further.
