class abcmodel.atmos.residual_layer.frozen.FrozenResidualState(theta, q, co2, u, v, h, delta_theta, delta_q, delta_co2, dz_h, thetav=<factory>, deltathetav=<factory>)

Bases: AbstractState

Residual layer state — the “frozen” daytime mixed layer aloft at night.

Captured from the convective mixed layer at sunset, preserved unchanged through the night, and used to re-arm the mixed layer at the next sunrise.

class abcmodel.atmos.residual_layer.frozen.FrozenResidualModel

Bases: object

Residual layer model — a passive container for the frozen daytime mixed layer.

The residual layer is captured from the convective mixed layer at the day→night transition and released back at the night→day transition.

init_state(theta=288.0, q=0.008, co2=422.0, u=6.0, v=-4.0, h=200.0, delta_theta=1.0, delta_q=-0.001, delta_co2=-44.0, dz_h=150.0)

Initialize the residual layer state.

Parameters:

• theta (float) – Residual layer potential temperature [K].

• q (float) – Residual layer specific humidity [kg/kg].

• co2 (float) – Residual layer CO2 [ppm].

• u (float) – Residual layer zonal wind [m/s].

• v (float) – Residual layer meridional wind [m/s].

• h (float) – Residual layer depth [m].

• delta_theta (float) – Potential temperature jump at top [K].

• delta_q (float) – Specific humidity jump at top [kg/kg].

• delta_co2 (float) – CO2 jump at top [ppm].

• dz_h (float) – Transition layer thickness [m].

Returns:

The initial residual layer state.
