Reanalysis downscaling : one 10 days long on 10 one day long ?

[gv871]

I am new to WRF (so bear with my question) and I am running two different WRF simulation, to down scale GFS data with 3 nested domains. The two simulations have same settings but they differ in the time control both for wps and wrf.
One is ran for 10 days:

start_date = '2024-11-01_00:00:00', '2024-11-01_00:00:00', '2024-11-01_00:00:00',
end_date   = '2024-11-10_00:00:00', '2024-11-10_00:00:00', '2024-11-10_00:00:00',

In the other I run, 10 simulations, one simulation for each day:

start_date = '2024-11-01_00:00:00', '2024-11-01_00:00:00', '2024-11-01_00:00:00',
end_date   = '2024-11-02_00:00:00', '2024-11-02_00:00:00', '2024-11-02_00:00:00',

...

start_date = '2024-11-09_00:00:00', '2024-11-09_00:00:00', '2024-11-09_00:00:00',   
end_date   = '2024-11-10_00:00:00', '2024-11-10_00:00:00', '2024-11-10_00:00:00',

Apart for the first day, the two simulations give differents results. Could it be connected to the

restart                             = .false.,

option ?
Any other suggestion is very welcome.
Thanks!

The model results are expected to be different if the initial time is different. This is because short-term model simulation is severely affected by initial condition. However, the difference should not be large, and the synoptic pattern at least should be consistent.
