What controls the spatio-temporal distribution of D-excess and O17-excess in precipitation? A general circulation model study

Fig 4. LGM present day (PD) difference in precipitation d-excess and O-excess in LMDZ and observations in Antarctica ([2, 11]). Fig 5: effect of different processes on the meridional gradient, seasonal cycle and LGM-PD difference of δO, d and O-excess. Fig 2. Seasonal cycle of precipitation δO, d and Oexcess in LMDZ and observations at Vostok (Antarctica) and at NEEM (Greenland: [4]). Fig 1.
