Braconnot et al. (2007b) previously demonstrated the surprising result that, in PMIP2 LGM simulations, the meridional shift of the ITCZ during the boreal summer differs in sign between the ensemble members. We find here that indeed, and contrary to expectations, two models shift the annual mean ITCZ toward the Northern Hemisphere. We note that, in both cases, these changes are expected given the change in AHTEQ and the relationship between PPenny and AHTEQ. We now discuss the cause of the negative (more southward) change in AHTEQ in these two models. Continue Reading…
