From: Precipitation isotopes and monsoon dynamics in the core monsoon zone of India

The co-variability of precipitation isotopes was observed at Dhanbad and Sagar, representing the core monsoon zone, and Darjeeling, representing the Himalayan foothills region. Panel (a) corresponds to the year 2013, while panels (b–d) represent 2016 to 2018. The red lines depict the isotopic records from Darjeeling, while the blue lines represent Dhanbad in panel (a) and Sagar in panels (b–d). Notably, an anti-phasing characteristic is evident in the isotopic records between these two regions.
