In A0015S and A0040S a maximum warming effect is simulated around 5◦S during SON. This is because the albedo change warming effect dominates over the evapotranspiration cooling effect resulted from the increased precipitation. The increased precipitation in response to afforestation is in line with the study of Liu et al. (2008). The autumn warming is consistent with the study by Lawrence et al. (2012). Their analysis show that the climate impacts of land cover change is most prominent in autumn with a 0.10 ◦C warming. However, using a land surface process model coupled to an atmospheric general circulation model, Bonan (1997) find that land-use effects on autumn temperatures are negligible. The main reason that our study differs from that of Bonan (1997)is the model used, which may affects the feedback.
