Abstract Rigorous analysis of measured isotopic composition (δ18O and δD) of 556 daily rainwater samples collected at four Indian stations viz., Jammu, Jorhat, Hyderabad and Ahmedabad, is done in conjunction with satellite and model derived meteorological and isotopic parameters to discern prominent hydrometeorological processes and factors in four different climatic zones in the Indian subcontinent. A new Indian Meteoric Water Line (IMWL), better representing the different climatic zones, including the semi-arid western India, has been defined: [δD = (7.6 ± 0.1) δ18O + (8 ± 1); R2 = 0.96; P

印度次大陆降雨的水文气象过程和蒸发：来自稳定同位素和气象参数的见解

摘要 结合卫星和模型得出的气象和同位素参数，对在印度四个站（查谟、乔哈特、海得拉巴和艾哈迈达巴德）收集的 556 个每日雨水样本的测量同位素组成（δ18O 和 δD）进行了严格分析，以识别突出的水文气象。印度次大陆四个不同气候带的过程和因素。一个新的印度流域水线 (IMWL) 更能代表不同的气候带，包括印度西部半干旱地区，已被定义：[δD = (7.6 ± 0.1) δ18O + (8 ± 1); R2 = 0.96；磷
