“…For the Shillong Plateau in eastern India, Breitenbach et al () showed that local ISM δD precip and δ 18 O precip values mostly reflect the variability of Bay of Bengal surface water and the moisture transport history, for example, convective processes over the SE Arabian Sea (Lekshmy, Midhun, Ramesh, & Jani, ), with minor influence of actual rainfall amount. The southern Himalayan front is influenced by varying quantities of ISM (Bookhagen & Burbank, ; Hren, Bookhagen, Blisniuk, Booth, & Chamberlain, ; Wulf, Bookhagen, & Scherler, ; Yu et al, ), Winter Westerly Disturbances (WWD) snowfall (Sanwal et al, ; Smith, Bookhagen, & Rheinwalt, ), and glacial melt (Racoviteanu, Armstrong, & Williams, ; Wilson, Williams, Kayastha, & Racoviteanu, ). Additionally, mesoscale weather anomalies occurring along mountain ranges and plateau margins might affect δD precip and δ 18 O precip values (Blisniuk & Stern, ; Cannon, Carvalho, Jones, & Bookhagen, ; Rohrmann et al, ).…”
