Summary
In order to improve prediction of some model output, an approach for the incorporation of dynamical entrainment and forced lifting into a 1-D cloud model is introduced.
It is shown that:
-
1.
The new parameterization of entrainment processes causes oscillations in the magnitudes of the vertical velocities, rain water content and temperature perturbations.
-
2.
The forced lifting component nonlinearly amplifies vertical velocities, temperature perturbations and rain water production. It causes descents of the local maxima (positive and negative) of the parameters mentioned.
-
3.
Model values of cloud top heights and radar reflectivity maxima with new parameter of entrainment are in better agreement with observations than former ones. The rain water mixing ratio maxima under influence of forced lifting component coincide well with observed regions of rainfall maxima.
