Maximum precipitation rates in the southern Blue Ridge Mountains of the southeastern United States

Abstract

In this study, relationships were identified between the maximum precipitation hourly rates observed in an event and selected topographic and geographic (TOPO/GEOG) attributes of the region. Rainfall events were identified from the hourly precipitation records at 44 stations in the Blue Ridge Mountains, USA, and classified according to the maximum rate of rainfall observed. Frequencies of low, moderate, and high intensity precipitation events were then statistically related to 30 TOPO/GEOG parameters. For the cool season, the strongest relationships were observed between low intensity events and several TOPO/GEOG attributes, especially northwest exposure. For the warm season, low and moderate intensity events exhibited strong relationships with elevation. -from Author
