Rate of Temperature–Precipitation Scaling in Rainfall Events

by Minghua Zhang 1 March 202322 February 2023

Future extreme rain will be embedded in shorter, more convective dominant rainfall events in the northeastern region of North America, leading to larger rate in future temperature-precipitation scaling.
