Quantifying the extremity of windstorms for regions featuring infrequent events
Abstract This paper introduces the Distribution‐Independent Storm Severity Index (DI‐SSI). The DI‐SSI represents an approach to quantify the severity of exceptional surface wind speeds of large scale windstorms that is complementary to the SSI introduced by Leckebusch et al . While the SSI approache...
