NEDAS.models.lorenz96.tracer_advection package

class NEDAS.models.lorenz96.tracer_advection.Lorenz96TracerModel(**kwargs)[source]

Bases: Lorenz96Model

Lorenz 1996 model extended with a tracer advection component.

State vector is [lorenz_state (nx), tracer (nx), source (nx)].

mean_velocity: float
pert_velocity_multiplier: float
diffusion_coef: float
e_folding: float
sink_rate: float
point_tracer_source_rate: float
positive_tracer: bool
bound_above_is_one: bool
write_var_to_file(var, **kwargs)[source]
generate_initial_condition()[source]
run(*args, **kwargs)[source]

Run the model forward in time.

Parameters:

  • *args – Arguments

  • **kwargs – Keyword arguments

Keyword Arguments:

  • time (datetime) – current time when forecast starts

  • restart_dir (str) – directory where restart files are located

  • forecast_period (int) – forecast period in hours

If self.ens_run_strategy == ‘batch’, the method will run all ensemble members in one go, expect additional kwargs[‘nens’] to be the ensemble size. If self.ens_run_strategy == ‘scheduler’, the method runs a single member indexed by kwargs[‘member’], and kwargs[‘worker_id’] is the pid assigned by the scheduler to run this method.
