Standard Precipitation Index - The precipitation sequence over the last months

Current Precipitation Pattern

The Standardized Precipitation Index (SPI) (Edwards, McKee 1997) defines the precipitation patterns of the last month, the last three month or the period of the last six month in relation to the previously established normal values. A negative SPI characterizes a time period drier than normal, hence a positive value distinguishes wet conditions. Following you can find an explanation of the calculation of the SPI:
