In the respect of the prediction of the large-scale wave, the IAP DF is better than the OSU DF, however, the OSU DF gives better predictions of zonal mean status than the IAP DF does. Another important contrast is that the level of small-scale noise of the IAP DF is higher than the OSU DF, on the contrary, the damping effect of the OSU DF on large-scale vortex field is stronger than the IAP DF.展开更多
