Precipitation thresholds for drought recognition: a further use of the standardized precipitation index, SPI [PDF]
WIT Transactions on Ecology and the Environment, 2013 Most of the methods used to analyse drought episodes include drought indices associated with quantitative scales and which are based upon instrumental variables, with particular emphasis for precipitation. Among such indices, one of the most common indices, if not the most widely used, is the standardized precipitation index (SPI), which assigns a ...
