WebThe truth is, there isn’t a straightforward answer because it depends on several factors. Firstly, the amount of rainfall required to end a drought varies depending on the severity and duration of the drought. A short-term drought may only require an inch or two of rain over a few days to provide relief. WebThe most common index used to define and monitor drought is the Palmer Drought Severity Index (PDSI), which attempts to measure the duration and intensity of long-term, …

WebDetails. The Palmer Drought Severity Index (PDSI), proposed by Palmer (1965), is a widely used drought indicator to quantify the long-term drought conditions, for an area at a certain time. The PDSI is a semi-physical based drought index calculated using the precipitation and potential evapotranspiration data, based on a simple two-layer bucket ... WebThe PDSI is calculated based on precipitation and temperature data, as well as the local Available Water Content (AWC) of the soil. From the inputs, all the basic terms of the …

Webmake use of the PDSI do not provide the methods of calcu-lation, so it is difﬁcult to compute the PDSI independently when doing research. Various computer codes for the cal-culation of the PDSI are available online, but they lack transparency and can often be difﬁcult to use. [8] Researchers are thus forced to use PDSI values sup- Weberage monthly values that facilitated comparability with the monthly PDSI information. 3.2.4.
