省时显式积分方案在有限区数值预报模式中的应用
APPPLICATION OF AN ECONOMICAL EXPLICIT TIME INTEGRATION SCHEME TO A LIMITED AREA NUMERICAL PREDICTION MODEL
【摘要】 本文作了有限区数值预报模式显式和省时显式时间积分方案的对比试验。对于冬季和夏季两个个例的计算结果表明,采用省时显式方案能大大提高计算效率,同时保持几乎和显式方案同样的预报结果。此外还讨论了省时显式方案中的侧边界处理方法。
【Abstract】 Comparision experiments were conducted for an explicit and economical explicit time integration scheme (EES) by use of a limited area numerical prediction model. The results from two cases of one winter and one summer prediction show that the EES could enhance the computationaI efficiency greatly, while produces almost the same prediction as the original explicit scheme model. In addition, the boundary condition processes used in EES are also discussed.
