Tree‐ring based reconstruction of the joint deficit index in Javan‐Roud Region, Kermanshah (Iran)

Tree‐ring based reconstruction of the joint deficit index in Javan‐Roud Region, Kermanshah (Iran)

ABSTRACT In this study, we examine the relationship between short‐ and long‐term effects of precipitation deficits, integrated in a drought index called ‘Joint Deficit Index (JDI)’, and tree‐ring growth of oak trees (Quercus infectoria) in the Javan‐Roud region, Kermanshah province (Iran). Precipita...

Zusammenfassung:ABSTRACT In this study, we examine the relationship between short‐ and long‐term effects of precipitation deficits, integrated in a drought index called ‘Joint Deficit Index (JDI)’, and tree‐ring growth of oak trees (Quercus infectoria) in the Javan‐Roud region, Kermanshah province (Iran). Precipitation data from regional climate stations cover the period 1968–2008, and the tree‐ring width chronology span over the period 1818–2008. This chronology is highly correlated with the JDI (January–September) series for the instrumental period (P
