Perpetual years

Running perpetual years

Perpetual years: Running the same year over and over again.

Pick the year you wanto to run. The beginning of this year also has to be the start year of your simulation.

Take care of leap years

Unless you are running a leap year set:

    Leap_years_L    = .false.  ( in 'gemclim_settings.nml', namelist: physics_cfgs )

    CLIMAT_leap_year=NO;     ( in 'configexp.dot.cfg' )

Lateral boundary conditions

When running LAM make sure that the nest_info-archive for December also contains data for January 1st of the same year.

SST & sea ice

In the file 'configexp.dot.cfg' set 'CLIMAT_anclim' to an empty file.
The scripts need a file to link to but the model must not find anything usable in it.

Set 'UM_EXEC_climato' to a file which contains the climatology (for each month) for 'TM' and 'LG' you want.
Make sure that 'IP2' contains the correct month.
