Mid-latitude westerlies sustain Asia's water lifeline for 2 billion people

Scientific studies increasingly recognize the westerlies as a major driver of water replenishment in the Asian Water Towers. However, the integration of this knowledge into broader climate models and water management strategies remains limited.
The Asian Water Towers are sustained not only by the monsoon but also by the mid-latitude westerlies, which operate for three-quarters of the year.
This dual atmospheric system is often overlooked in mainstream narratives, which tend to emphasize monsoonal patterns. Indigenous knowledge systems offer a complementary understanding of these dynamics, emphasizing long-term ecological balance. Integrating scientific and traditional knowledge into transboundary governance frameworks can enhance water security for 2 billion people. By recognizing the full complexity of atmospheric processes and the voices of those most affected, we can move toward more equitable and sustainable water management.
