We present a new dynamic dominant height growth model based on Cieszewski’s generalized algebraic
difference approach (GADA) advanced dynamic site equation strengthened by the use of explicit climate and soil
variables (i.e., H = f(H0,T0, T, site conditions)). The results suggest that the inclusion of climatic variables would
improve the applicability of the inter-regional model in regions in which climate and soil type lead to intra-regional
variability. The new model reduces the bias present in a previous dynamic model that did not include climatic attributes
and improves the model efficiency across the different age classes. Climate has a multiplicative effect on
dominant tree growth in the early development stages (<20 years) and an additive effect in older stands
