Integrating nonstationary behaviors of typhoon and non-typhoon extreme rainfall events in East Asia

Abstract Extreme rainfall events in East Asia can be derived from the two subcomponents of tropical cyclones (TC) and non-TC based rainfall (mostly summer monsoons). Critical natural hazards including floods and landslides occur repeatedly due to the heavy rainfall associated with the two subcompone...
