A THREE-DIMENSIONAL ELASTIC NESTED-GRID MESO-(β-γ) SCALE ATMOSPHERIC MODEL——PART Ⅱ:MODEL VALIDATION

By using the model developed in Part Ⅰ of the sister papers,simulations of severe storm,winter airflow and snowfall over a mountain,as well as mountain-valley winds and sea breeze are performed.Different functions of the model are verified through the computation and special emphasis is put on some important properties of the meso-(β-γ) systems frequently occurring.The simulation results of the cases are agreeable to field observations,conceptual models,and previous numerical studies.It is shown that the model is applicable for the researches and prediction of various local and/or regional weather processes,and capable of describing their macro-and micro-structures,influences of orographic and underlying-surface forcing,and interaction between meso-β and meso-γ scales.In addition,the evolutional characteristics and mechanisms of the modeled processes are also analyzed.
