| Abstract: | The role of vegetation feedback on the climate in response to insolation forcing during the mid-Holocene was investigated by using results from six coupled ocean-atmosphere-vegetation general circulation models and coupled ocean-atmosphere general circulation models in the Paleoclimate Modeling Intercomparison Project Phase 2(PMIP 2). Temperature and precipitation changes compared to pre-industrial(1750A.D.)control runs in summer(June to September)at the Mid-Holocene in three areas were analyzed:(1)Central Asia whose climate is affected by South Asian monsoon and Westerly wind; (2)Arid Central Asian area is marched with Westerly wind and Asian monsoon; (3)East Asian monsoon area is mainly influenced by East Asian monsoon.For the different models and the vegetation models used by the different models,there are variations in the mean temperature and precipitation changes(6ka-0ka)across models.Feature common to all models include warmer temperature and more precipitation through analysis of the results of the mean summer temperature and precipitation changes.Since vegetation changes are different in different areas between different models,the vegetation feedback on the climate in response to insolation forcing is different across models and areas.In East Asian Monsoon area,the results show different variations between different models.FOAM,ECHAM5.3-MPIOM127-LPJ and MRI-CGCM2.3.4FA modeled temperature show lower temperature compared to pre-industrial control runs.Results from ECBILTCLIOVECODE,UBRIS-HADCM3M2 and MRI-CGCM2.3.4NFA show that the improved vegetation cover leads to a warmer mean summer surface temperature.But the precipitation changes caused by the vegetation cover changes are quite different and the results are not ideal.In the arid Central Asia,ECBILTCLIOVECODE,FOAM and UBRIS-HADCM3M2 modeled results show that the improved vegetation cover changes lead to a lower mean summer surface temperature.But the other models results show that the improved vegetation cover changes lead to a warmer mean summer surface temperature.All models show the mean summer surface temperature is about 0.5℃ lower than present in Xinjiang area of North West China except MRI-CGCM2.3.4NFA.There is cross-model change in the variance of the mean summer precipitation in the arid Central Asia.In Central Asia,when the vegetation covers coupled in the models are improved, all models show a little difference in mean summer surface temperatures except MRI-CGCM2.3.4NFA, and all models show more mean summer precipitation than present except FOAM. Thus it can be seen,except for insolation forcing,vegetation cover changes has an important effect on climate change in the research areas during the mid-Holocene. |
