Short summary
We develop a novel framework to assess process connectivity in runoff generation through intensity integration. Applying this framework to 6,603 catchments globally over 1950–2020, we quantify the spatial patterns of process connectivity, diagnose their influencing factors, and examine their long-term trends and event-scale responses to precipitation intensity. Our findings enhance the understanding of runoff generation processes under the changing environment.
