Therefore, comparison of measured and simulated water balance cannot be di-
rectly used for validation of the model-generated precipitation. According to the
non-scaled MM5 output for the period 1961–1990, mean precipitation for the

was reduced to 1750mm
y−1, i.e. by approximately 2%. This difference
