Comparison and Examination of Dynamic Frameworks of IAP and OSU AGCM


doi: 10.1007/BF02661533

  • A brief description of the dynamic framework of the IAP 2-L AGCM (referred as “IAP DF”) is presented in contrast with the corresponding “OSU DF” and preliminary comparison and examination of the IAP DF and the OSL DF with the aid of numerical experiments using a set of baroclinic Rossby-Haurwitz wave initial conditions is performed.The results of the numerical experiments show that both the IAP DF and the OSU DF are long-term computational stable and are able to simulate the fundamental behavior of the Rossby-Haurwitz wave under the lim-itation of 7.5 minutes time interval. 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.

Abstract: A brief description of the dynamic framework of the IAP 2-L AGCM (referred as “IAP DF”) is presented in contrast with the corresponding “OSU DF” and preliminary comparison and examination of the IAP DF and the OSL DF with the aid of numerical experiments using a set of baroclinic Rossby-Haurwitz wave initial conditions is performed.The results of the numerical experiments show that both the IAP DF and the OSU DF are long-term computational stable and are able to simulate the fundamental behavior of the Rossby-Haurwitz wave under the lim-itation of 7.5 minutes time interval. 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.
