Abstract

This report summarizes the development of a methodology to describe the characteristics of coherent turbulence in the nocturnal boundary layer that are known to induce excessive structural loads and component vibration in operating wind turbines and suggestions for applying those results in the development of techniques of real-time detection and prediction that can be used for mitagationpurposes.
