包络地形和重力波拖曳对气候模拟效果的影响
EFFECTS OF ENVELOPE OROGRAPHY AND GRAVITY WAVE DRAG ON PERFORMANCE OF CLIMATE MODELING
-
摘要: 该文用Nju-PσM的数值试验, 研究了包络地形和地形重力波拖曳作用对7月气候模拟效果的影响.通过试验结果的对比分析, 发现包络地形和重力波拖曳作用都可在一定程度上改善模式的模拟性能, 使模拟结果更符合气候实况.Abstract: The Nju-PσM is used to study the effects of envelope orography and gravity wave drag on July climate modeling. The results of analysis and comparison show that envelope orography and gravity wave drag could improve the modeling performance to some extent and result in more realistic simulations.
