Economical Explicit Integration of High Resolution Regional Numerical Prediction Models
高分辨有限区数值预报模式的省时显式积分

In this paper, an economical explicit scheme is used to integrate two high resolution numerial prediction models. It is shown that this new scheme for time integration effectively saves the computer resources without notable changes in the forecast fields. The problems of lateral boundary treatment needed When this scheme is applied to the limited area model are also discussed. A new boundary filter equivalent to that of leap frog scheme is proposed.
