1Subseasonal features of the Asian summer monsoon in the NCEP climate forecast system显示文摘The operational climate forecast system(CFS)of the US National Centers for Environmental Prediction provides climate predictions over the world,and CFS products are becoming an important source of information for regional climate predictions in many Asian countries where monsoon climate dominates.Recent studies have shown that,on monthly-to-seasonal time-scales,the CFS is highly skillful in simulating and predicting the variability of the Asian monsoon.The higher-frequency variability of the Asian summer monsoon in the CFS is analyzed,using output from a version with a spectral triangular truncation of 126 waves in horizontal and 64 sigma layers in vertical,focusing on synoptic,quasi-biweekly,and intraseasonal time-scales.The onset processes of different regional monsoon components were investigated within Asia.Although the CFS generally overestimates variability of monsoon on these time-scales,it successfully captures many major features of the variance patterns,especially for the synoptic time-scale.The CFS also captures the timing of summer monsoon onsets over India and the Indo-China Peninsula.However,it encounters difficulties in simulating the onset of the South China Sea monsoon.The success and failure of the CFS in simulating the onset of monsoon precipitation can also be seen from the associated features of simulated atmospheric circulation processes.Overall,the CFS is capable of simulating the synoptic-to-intraseasonal variability of the Asian summer monsoon with skills.As for seasonal-to-interannual time-scales shown previously,the model is expected to possess a potential for skillful predictions of the high-frequency variability of the Asian monsoon.Song YANG WEN Min R Wayne HIGGINS 2008Acta Oceanologica Sinica2008,27,3:3
2Impacts of Land Process on the Onset and Evolution of Asian Summer Monsoon in the NCEP Climate Forecast System显示文摘Impacts of land models and initial land conditions(ICs) on the Asian summer monsoon,especially its onset,were investigated using the NCEP Climate Forecast System(CFS).Two land models,the Oregon State University(OSU) land model and the NCEP,OSU,Air Force,and Hydrologic Research Laboratory(Noah) land model,were used to get parallel experiments.The experiments also used land ICs from the NCEP/Department of Energy(DOE) Global Reanalysis 2(GR2) and the Global Land Data Assimilation System(GLDAS).Previous studies have demonstrated that,a systematic weak bias appears in the modeled monsoon,and this bias may be related to a cold bias over the Asian land mass.Results of the current study show that replacement of the OSU land model by the Noah land model improved the model's cold bias and produced improved monsoon precipitation and circulation patterns.The CFS predicted monsoon with greater proficiency in El Nin o years,compared to La Nin a years,and the Noah model performed better than the OSU model in monsoon predictions for individual years.These improvements occurred not only in relation to monsoon onset in late spring but also to monsoon intensity in summer.Our analysis of the monsoon features over the India peninsula,the Indo-China peninsula,and the South Chinese Sea indicates different degrees of improvement.Furthermore,a change in the land models led to more remarkable improvement in monsoon prediction than did a change from the GR2 land ICs to the GLDAS land ICs.Song YANG 温敏 Rongqian YANG Wayne HIGGINS 张人禾 2011Advances in Atmospheric Sciences2011,28,6:3
