大气环流模式SAMIL模拟的夏季全球加热场和东亚夏季风
Performances of SAMIL on the Global Heating and the East Asian Summer Monsoon
摘要
Abstract
The monsoon has great impacts on the regional and global climate to which many scientists dedicate them-selves for better understanding it theoretically and numerically. Based on Thermal Adaptation Theory, the authors evaluate the performances on the global diabatic heating of the newest spectral atmospheric general circulation model (SAMIL, hereafter), developed at the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences (LASG/IAP), and further make some analyses and explanations on the simulations of the components of the East Asian Summer Monsoon (EASM). The results show that SAMIL has good performances on the quadruplet heating pattern (LOSEC-OD) in the boreal subtropics compared to the NCEP/DOE AMIP-Ⅱ Reanalysis (Reanalysis-2), except for biases in strength. The sensible heating simulated by SAMIL is universally stronger over the continent, and the condensation heating is stronger on the two sides of the Indian peninsula and over the western Pacific (especially at 10°N and 10°S), whereas it is weaker near the equator and over the regions of the Indo-China Peninsula and the South China Sea. The authors further point out that the South Asia high can be well simulated and main features of the subtropical high over the western Pacific can be generally captured. But the subtropical high has stronger strength and more westward location, which are mainly caused by the stronger latent heating over the western Pacific (near 30°N). It also can exhibit the two centers of the westerly jet which is some 10 m/s smaller than that from Reanalysis-2 resulting from the weaker latent heat, sensible heat, and shortwave radiation. It further points out that the cloud parameterization and cumulus convective parameterization cause the biases in the sensible heating and latent heating. From this point, modifying and updating the physical parameterizations in SAMIL will be the priority in the near future.关键词
