Analysis of compound hot, dry winds using Copula

Hot, dry winds affect evapotranspiration and plant water balance. These events result in more water use and severe damage to agricultural production by declining crop yields. The goal of this project is to study how the frequency of extreme wind speed change compound with extreme low humidity and high temperature in the Great Plains. The probability of hot, dry winds is expected to be high in this region where high speed winds occur most in the US. A theoretical copula framework is provided to analyze the joint behavior of compound hot, dry wind extremes. Results of this study provide valuable information about the changes in the probability of hot, dry winds for more efficient water management strategies and effective risk management in the central United States.
