How to use SpeedyWeather to diagnose model run instability caused by initial conditions.

[rocroc2017]

Dear Dr. Klöwer
I plot the simulation.prognostic_variables(temp,humid,pres,vor and div) in layer8
temp in day 0 and day 6


humid in day 0 and day 6


pres in day 0 and day6


vor in day 0 and day6


div in day 0 and day6

I find there are small changes in temp, humid and pres, but there are large changes in vor and div.
However, I am unsure of the next steps to take in order to identify the issue and ensure the model can run stably for long-term integration. Could you please provide some suggestions? Thank you very much.
