This paper proposes an ontology similarity assessment method,this method constructs virtual instances for every concept node and takes the structure of ontology into consideration,then we adjust the similarity with WordNet.

In this paper, a newly established "South China Regional Short Range Climate Prediction Model System" is introduced and its performance is analyzed in real case simulation.
