A Self-Calibrating Palmer Drought Severity Index
The Palmer Drought Severity Index (PDSI) has been used for more than 30 years to quantify the long-term drought conditions for a given location and time. However, a common critique of the PDSI is that the behavior of the index at various locations is inconsistent, making spatial comparisons of PDSI values difficult, if not meaningless. A self-calibrating Palmer Drought Severity Index (SC-PDSI) ...

متن کاملAssessing Agricultural Drought in the Anthropocene: A Modified Palmer Drought Severity Index
In the current human-influenced era, drought is initiated by natural and human drivers, and human activities are as integral to drought as meteorological factors. In large irrigated agricultural regions with high levels of human intervention, where the natural farmland soil moisture has usually been changed significantly by high-frequency irrigation, the actual severity of agricultural drought ...
متن کاملAssessment of the Palmer drought severity index in arid and semi arid rangeland: (Case study: Qom province, Iran)
Drought is a normal, recurring feature of climate phenomena; it may occur virtually in all climatic regions. The effects of drought accumulate slowly and its impacts are spread over a larger geographical area than other natural hazards. Drought is a natural hazard originating from a deficiency of precipitation that result in a water shortage for some activities or some groups and is often assoc...
