This paper describes the dynamic initialization procedures of a two-dimensional lake breeze model, based on radiosonde data at one site. Three approaches of initialization have been tested. The results prove that dynamical balance between mass and momentum fields can be obtained from unbalanced, inexact first guesses, but there is an obvious difference between resufts calculated with each initialization procedure. In comparison, we found that the approach, onedimensional dynamic initialization with nudging, probably is preferable to the others.
