Spatial connections in regional climate model rainfall outputs at different temporal scales: Application of network theory

摘要

Highlights?Network theory is applied to study rainfall outputs from regional climate model.?Spatial rainfall connections at different temporal scales are examined for scaling.?Rainfall connections at different temporal scales have different network properties.?Intermediate temporal scales serve as a transition for rainfall spatial connections.?Coupling small-world and scale-free networks is suitable for rainfall scaling model.AbstractUnderstanding the spatial and temporal variability of rainfall has always been a great challenge, and the impacts of climate change further complicate this issue. The present study employs the concepts of complex networks to study the spatial connections in rainfall, with emphasis on climate change and rainfall scaling.
